About converting JPG to PNG
Converting JPG to PNG re-encodes the image in the PNG format using your browser's canvas, so you can switch formats without extra software.
Everything happens on your device — nothing is uploaded. If PNG has no transparency, any transparent areas are filled with white, and FileTinker warns you first.
Convert JPG to PNG when you need lossless editing, a transparent background you can add later, or crisp text and screenshots without JPG's blocky artefacts. Note that converting cannot recover detail already lost in the JPG, and the PNG will usually be larger because it is uncompressed in a lossless way.
Frequently asked questions
How do I convert JPG to PNG?
Drag your JPG image into the tool above and press Convert. FileTinker re-encodes it as PNG in your browser, then you download the result.
Will converting JPG to PNG reduce the quality?
Converting to PNG re-encodes the image. PNG is lossless, JPG and WebP use light compression to keep files small; FileTinker uses a high-quality setting so the difference is hard to see.
What happens to transparency when I convert to PNG?
JPG has no transparency, so any transparent areas are filled with white. PNG and WebP keep transparency intact.
Are my images uploaded anywhere?
No. Conversion happens entirely in your browser — your image never leaves your device and nothing is stored on a server.
Does converting JPG to PNG improve image quality?
No, it preserves the current quality but cannot restore detail the JPG already compressed away. PNG simply stops further loss, which is useful before editing or for sharp graphics and text.
