Convert JPG to PNG entirely in your browser — the file never leaves your device. PNG is lossless, so the output stops any further quality loss and preserves every pixel intact for future edits. It is the right choice before compositing, layering in a design tool, or archiving a photo at its best quality. Transparency editing also becomes possible once the image is in PNG format.
How to use JPG to PNG

Processed locally with the Canvas API — nothing is uploaded to any server.

Re-encoded as PNG
Pixels are decoded from the JPEG and written to a lossless PNG, preventing any further JPEG artifacts on re-save.

Download instantly
No queue, no signup — the PNG is generated on your machine and downloaded immediately.
Common questions
Will the file get bigger?+
Usually yes — PNG is lossless so photos grow vs JPG. Use it when you need editing quality or transparency, not a smaller file size.
Is anything uploaded?+
No. Conversion runs 100% in your browser; the image never touches a server.
Does it improve quality?+
It cannot recover detail already lost to JPEG, but it prevents any further quality loss in future edits and re-saves.
Can I add transparency after converting?+
PNG supports an alpha channel, so you can add transparency later in any image editor (GIMP, Photoshop, Figma). The conversion itself outputs an opaque image.
