How to Open JPG File (JPEG) on Windows, Mac, iPhone & Android

What is a JPG file?

A JPG file is a photo or picture saved in the JPEG image format, the most common image format on the web and on phone and camera memory cards. JPEG stands for Joint Photographic Experts Group, the committee behind the standard, which was approved as ITU-T Recommendation T.81 in September 1992. The same format uses the extensions .jpg, .jpeg, .jpe and .jfif, and its MIME type is image/jpeg. Because support is built into every operating system, you can open a JPG file on any device without installing anything.

JPEG is a "lossy" format: it shrinks a photo by discarding detail the eye is unlikely to notice, typically to around a tenth of its uncompressed size. That makes JPG ideal for photos, but not for screenshots with sharp text or for images that need a transparent background (JPEG has no transparency; use PNG for those).

Besides the pixels, a JPG can carry hidden EXIF metadata: the camera make and model, the date and time the photo was taken, exposure settings such as ISO and shutter speed, and — on most phones with location access turned on — the GPS coordinates of where it was taken. This metadata is invisible in a normal viewer but travels with the file wherever it's shared.

How to open a JPG file on Windows 11 and 10

1. Double-click the photo — it opens in the built-in Photos app (listed as Microsoft Photos). Use the arrow keys to move through other photos in the same folder.
2. To open JPG files in another app, right-click the photo and choose Open with > Paint, Microsoft Edge or any installed editor. Paint is the quickest test when Photos misbehaves.
3. To see the camera details without any tool, right-click the file, choose Properties, then the Details tab. The same tab has Remove Properties and Personal Information for stripping metadata.
4. To see thumbnails of a whole folder, in File Explorer choose View > Large icons.

JPG won't open in Windows 11 Photos: error messages and fixes

If you can't open a JPG file in Photos but the same photo opens in Paint or a browser, the photo is fine and the Photos app needs fixing. Start by opening the file in Paint: that one test tells you which half of this section you need.

Fix the Photos app, step by step

1. Update Photos: open the Microsoft Store, go to Library (Downloads on older versions) and install any updates, then also install pending updates in Settings > Windows Update.
2. Repair: go to Settings > Apps > Installed apps, click the … next to Microsoft Photos, choose Advanced options and click Repair. Try the photo again.
3. Reset: if Repair didn't help, click Reset on the same page. This resets the app's settings and data; your photo files themselves are not deleted.
4. Reinstall: as a last resort, open Terminal (Admin) and run Get-AppxPackage *Microsoft.Windows.Photos* | Remove-AppxPackage, then install Microsoft Photos again from the Microsoft Store. This is also the fix if the Photos app is missing altogether.

While you fix Photos, you can still view the picture in Paint, Edge or the online viewer above. If some JPGs still won't open after a repair but open in other apps, re-save them from Paint (File > Save as > JPEG picture); this rewrites the header and metadata that tripped Photos up.

"JPG file is not supported": when it's really HEIC, WEBP or AVIF

When an app says a JPG isn't supported, the file usually isn't a JPEG at all. Images saved from websites, messaging apps or iPhones are often WEBP, HEIC or AVIF files that were given a .jpg name. Apps that trust the name try to decode it as a JPEG and fail, and even apps that read the content can't show it without the right codec (HEIC without the HEVC extension, for example).

1. Check whether it's really a JPEG

Drop the file into the tool above: it reads the first bytes and tells you the real format. A renamed WEBP, PNG or AVIF is shown anyway, with a button to save a genuine JPG copy; a HEIC is identified with a link to the converter. Without the tool, open the file in Notepad and look at the first few characters:

Close Notepad without saving. If none of these match, the file identifier on this site checks dozens of other signatures. For iPhone photos, setting Settings > Camera > Formats > Most Compatible makes the camera save JPEG instead of HEIC from now on.

2. Check that the file is complete

Look at the size in File Explorer. A 0 KB file, or one far smaller than similar photos, was cut off during download or copying and has to be fetched again. Files in a OneDrive or other cloud-synced folder that show a cloud icon are only placeholders until downloaded — if you're offline, they can't open.

3. Repair the Photos app

If the file is a genuine, complete JPEG that opens fine in a browser or Paint but not in Photos, follow the Repair and Reset steps above.

JPG opens as text or garbled characters

If you open a JPG file and see lines of random symbols, it has been opened by a text editor, or isn't an image file at all. The first characters tell you which:

• Starts with ÿØÿ followed by gibberish: it's a normal JPEG opened in Notepad or another text editor, usually because a text editor became the default app. Close it without saving (saving can damage the photo) and set Photos or Preview as the default.
• Starts with /9j/ or data:image/jpeg;base64,: the file is a photo encoded as Base64 text, as some web apps, APIs and email exports produce. Drop it into the tool above: it decodes the text and lets you save a normal .jpg.
• Starts with <!DOCTYPE html> or <html: you saved the web page around the picture, not the picture. Open the page again and use right-click > Save image as.
• Name ends in .jpg.txt once extensions are visible: the file was saved as text. If it starts with ÿØÿ, rename it to end in .jpg.

"Name (1).jpg" and other odd JPG file names

A file called photo (1).jpg is a normal JPG: browsers such as Chrome and Edge add (1), (2) and so on when a file with the same name already exists in the download folder. You open a JPG file with (1) in its name exactly like any other photo; delete the copies you don't need.

• photo.jpg (1) or photo.jpg(1) — the number ended up after the extension, so Windows no longer recognizes it as a picture. Rename it to photo (1).jpg.
• photo.jpg.jpg — harmless; it shows up when an extension was typed while extensions were hidden.
• photo.jpg.exe, .scr or .js — not a photo. Don't open it; it's a common malware disguise.
• .jfif or .jpe — the same JPEG format with another extension; rename to .jpg if a website refuses it.

How to open a JPG file on Mac

1. Double-click the file to open it in Preview, macOS's built-in image viewer. To glance at it without opening an app, select it in Finder and press Space (Quick Look).
2. In Preview, click the Info button in the toolbar (or choose Tools > Show Inspector) to see the EXIF details, including where the photo was taken if it contains GPS data.
3. To add the photo to your library, drag it into the Photos app. To edit, use Preview's Markup toolbar or any editor.

How to open JPG files on iPhone & Android

Both iPhone and Android open JPG files natively; the only question is where the file landed.

iPhone and iPad

• Photos you take are in the Photos app. A JPG sent in Mail or Messages opens with a tap.
• A downloaded JPG is in the Files app (usually Downloads); tap it to preview. To move it into Photos, tap the Share button and choose Save Image.
• The iPhone camera normally saves HEIC, not JPG. To get JPG photos, set Settings > Camera > Formats to Most Compatible.

Android

• Photos open in Google Photos or your phone's Gallery app (Samsung Gallery on Galaxy phones).
• A downloaded or received JPG is in Files by Google (or Samsung My Files) under Downloads or Images; tap it to open. If Android asks which app to use, pick your photo app and choose Always.
• A JPG inside a ZIP must be extracted first — see how to open ZIP files.

How to open JPG files on Chromebook and Linux

Chromebook: open the Launcher, start the Files app, find the photo in Downloads, My Drive or Camera, and double-click it. It opens in the built-in Gallery app, where you can also crop, rotate and adjust it.

Linux: every desktop ships an image viewer that opens JPG files on double-click — GNOME's Image Viewer and KDE's Gwenview, for example — and GIMP edits them. From a terminal, xdg-open photo.jpg opens the photo in the default viewer.

Change which app opens JPG files

If double-clicking a photo launches a browser, a text editor or an app you don't recognize, the file is fine — only the default app changed (often after installing a new image or PDF program). The app you choose below is the one that will open JPG files from then on.

Windows 11

1. Right-click the photo and choose Open with > Choose another app.
2. Pick the app you want (for example Photos), then click Always. "Just once" opens it without changing anything.
3. To check every image type at once, go to Settings > Apps > Default apps and type .jpg into the box for setting a default by file type. Repeat for .jpeg and .jfif — Windows treats each extension separately, which is why one kind of JPG can open in Photos while another opens in a browser.

Mac

1. Select a JPG in Finder and press Command-I (File > Get Info).
2. Under Open with, choose the app — Preview is the macOS default.
3. Click Change All… to apply it to every .jpg file, not just this one.

On Android, the default is cleared from the current handler's page under Settings > Apps (look for "Open by default" or "Set as default", depending on the phone); the next time you open a photo, Android asks which app to use.

Does a JPG file reveal your location?

It can, and it's worth checking before you post a photo publicly. When a smartphone camera has location access, it typically embeds the latitude and longitude where the photo was taken directly into the file's EXIF data — often accurate to a few meters. Anyone who gets the original file (not a re-compressed version some social platforms create) and looks at its metadata can see where you were standing.

The tool on this page reads this data and shows plainly whether it's present, so you can decide before sharing: open the JPG file in the tool before you post it. If it finds GPS coordinates, use the "Download without metadata" button: it redraws the photo on a blank canvas in your browser and saves a new JPG, which drops all EXIF and GPS data. The picture looks the same (it's re-saved at high quality, and turned upright if the camera stored a rotation tag), though it isn't a byte-for-byte copy of the original.

• Windows: right-click > Properties > Details > Remove Properties and Personal Information.
• iPhone: in the share sheet, tap Options and turn off Location before sending.
• Stop recording location: turn off location access for the camera app in your phone's privacy settings.

JPG vs JPEG — what's the difference?

There is no difference: .jpg and .jpeg are the identical file format, and so are .jpe and .jfif. The three-letter .jpg exists because MS-DOS and early Windows used "8.3" file names, which allowed at most three characters after the dot, so "JPEG" had to be shortened. Macs and Linux never had that limit, so .jpeg stayed common there. Every program that opens one opens the others, and renaming between them changes nothing inside the file.

To open a JPEG file, follow exactly the same steps as for a .jpg; how to view a JPEG file is no different on any device. Which spelling to use? Either. If a website upload form rejects one spelling, rename the file to the other. For a full comparison with PNG, HEIC, AVIF and WEBP, see best image format.

Save a JPG as PDF, PNG or WEBP

You never need to convert a photo just to open a JPG file; convert only when a form or program asks for another format. Forms and job portals often want a PDF, and some editors need a lossless copy. Each conversion has its own free page on this site; they all run in your browser without uploading the photo.

Common JPG problems: corrupted, gray or rotated photos

"This file is corrupted and cannot be opened"

Usually the file was cut off during a download or transfer, or the original save was interrupted. Re-download it from the original source; a partially transferred file can't be completed afterwards.

Image opens but looks like solid gray or garbled blocks

The header is intact but the compressed image data is damaged. Some viewers can still show the undamaged top portion; full recovery usually isn't possible without the original. See the recovery steps below.

Photo appears rotated the wrong way

Most cameras store an "Orientation" tag in EXIF rather than physically rotating the pixels, and some apps and websites ignore it. Rotate it in an editor and save, or use the tool's "Download without metadata" button, which saves the photo already turned upright.

Recover a corrupted JPG (after data recovery, SD card or transfer errors)

Photos recovered with tools like PhotoRec or Recuva, or copied from a failing memory card, often open as a gray rectangle, show only the top part, or come out with shifted colors in the lower half. If you can't open a JPG file recovered this way, part of it was overwritten or never read correctly. Missing image data can't be recreated, but you can usually salvage more than you'd expect:

1. Stop using the card or drive until you're done recovering. Every new photo written to it can overwrite more of the damaged files.
2. Try a more tolerant viewer. Browsers, GIMP and IrfanView often display the undamaged part of a broken JPG where Photos shows nothing. Take a screenshot or "Save as" from there to keep what's visible.
3. Extract the embedded preview. Most camera and phone JPGs carry a small thumbnail — and many cameras a larger preview — inside their EXIF data, stored separately from the main image. The free ExifTool can pull it out even when the main picture is broken.
4. Re-run recovery with a different tool or a different scan mode; recovery programs reassemble fragments differently, and a second pass sometimes produces a complete file.
5. Header-repair software (several paid tools exist) can rebuild a JPG whose header is damaged by borrowing the structure from a healthy photo taken with the same camera. It can't restore pixels that were overwritten.

Make a JPG smaller for email or uploads

Phone photos are often 3–8 MB each, which trips upload limits on job portals, government forms and email. Reducing the pixel dimensions shrinks the file far more than lowering quality does — a photo resized to 1600 pixels on its longest side is usually well under 1 MB and still looks sharp on screen.

• Windows: open the photo in Paint, choose Resize (Ctrl+W), set a percentage or pixel size with "Maintain aspect ratio" ticked, then File > Save as > JPEG. The Photos app also offers a Resize image option in its "…" menu.
• Mac: in Preview, choose Tools > Adjust Size, or use File > Export and drag the Quality slider down.
• iPhone: when you attach photos in the Mail app, it offers to send them at Small, Medium, Large or Actual Size.
• Command line: magick photo.jpg -resize 1600x1600 -quality 82 photo-small.jpg (ImageMagick) keeps the aspect ratio and fits the photo inside 1600×1600.
