Convert PNG to JPG
Turn a .png image into a JPG — right in your browser, with a real re-encode via canvas, not a server upload. Typically a fraction of the original PNG's file size.

Drop a .png file below. Your browser decodes it, then it's re-encoded as a real JPG on a canvas — previewed here, ready to download.

Why convert PNG to JPG
PNG's lossless compression makes for large files, especially for photos and screenshots. JPG produces a dramatically smaller file for photographic content, which matters when you're emailing an image, attaching it to a form, or need it under a file-size limit and don't need PNG's transparency or pixel-perfect losslessness.
Edge cases this tool handles
Transparency
JPG has no transparency channel, so any transparent or semi-transparent pixels in the source PNG are flattened onto a white background rather than turning black or being silently corrupted.
Screenshots and flat-color graphics
PNG is often the better format for these (sharp text and edges compress more efficiently as lossless PNG), so converting to JPG can sometimes produce visible compression artifacts around hard edges — this tool is best suited to photographic PNGs.
Repeated conversions
The output JPG is written at a high (92%) quality setting, which is visually lossless for almost all photos, but converting back and forth between JPG and PNG repeatedly will still accumulate JPG's generation loss each time it passes through JPG.
Frequently asked questions
Does converting PNG to JPG upload my file anywhere?
No. The image is decoded and re-encoded entirely inside your browser using a canvas — the file never leaves your device or touches a server.
What happens to transparency?
JPG doesn't support transparency, so any transparent areas in the source PNG are flattened onto a white background before conversion, rather than turning black or being silently corrupted.
How much smaller will the file be?
It varies a lot by image content, but JPG very often produces a substantially smaller file than an equivalent PNG for photographic images — screenshots and flat-color graphics see smaller, sometimes negative, savings since PNG already compresses that content well.
Will the image quality drop?
Some quality loss is inherent to JPG's lossy compression, even from a lossless PNG source. The tool encodes at a high quality setting (92%), which is visually lossless for almost all photos.
