Convert JPG to PNG
Turn a .jpg photo into a lossless PNG — right in your browser, with a real re-encode via canvas, not a server upload.
Convert a JPG File to PNG
Drop a .jpg file below. Your browser decodes it, then it's re-encoded as a real PNG on a canvas — previewed here, ready to download.

Why convert JPG to PNG
Some tools, templates and upload forms specifically require PNG rather than JPG — design software that expects a transparency channel to be available, certain print or asset pipelines, or a form that only accepts PNG. Converting gives you a PNG file, though it's worth knowing upfront that it can't undo JPG's original compression (see the edge cases below).
Edge cases this tool handles
This doesn't undo JPG's original compression
The source JPG was already compressed when it was created, and that compression is permanent — converting it to PNG stores those same pixels losslessly from that point on, but doesn't recover detail the original JPG encoding discarded.
No transparency is added
A JPG never had an alpha channel to begin with, so the output PNG is fully opaque — converting to PNG doesn't create transparency where there wasn't any.
Larger file size
Expect the PNG to be noticeably larger than the source JPG, especially for photos — that's the tradeoff for PNG's lossless storage of every pixel from that point forward.
Frequently asked questions
Does converting JPG to PNG 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.
Will converting to PNG improve the image quality?
No — the source JPG's compression already happened and can't be reversed. Converting to PNG losslessly preserves the pixels exactly as they are from that point on, but doesn't recover detail the original JPG compression discarded.
Will the PNG have transparency?
No — a JPG file never has an alpha channel, so there's no transparency to carry over. The output PNG is fully opaque, just like the source.
Why is the PNG file so much bigger than the JPG?
PNG uses lossless compression, which simply can't shrink photographic detail as much as JPG's lossy compression does. That's the normal, expected tradeoff for a format that doesn't discard any image data.
