Converting to PNG is useful when a platform demands the extension or when you plan to edit the image over several passes: being lossless, PNG does not accumulate degradation with every save, unlike JPG.
Keep in mind the conversion cannot recover quality the JPG already lost, nor does it add transparency: you get an exact copy of the current pixels in a lossless container, usually at a much larger size.
How it works
- 1
Drop your JPGs into the upload zone.
- 2
PNG is preselected as output.
- 3
Download the PNGs, ready for editing.
Frequently asked questions
Does converting to PNG improve my JPG’s quality?
No: no converter can recover information the JPG already discarded. PNG prevents future losses when editing and re-saving, but does not undo past ones.
Will the PNG have transparency?
Not automatically: a JPG has no alpha channel, so the PNG keeps the same opaque background. You would need an editor to cut out the background.
Are my photos uploaded to a server?
No. All processing happens inside your browser using the Canvas API: your files never leave your device, there are no upload queues, and the tool even works offline once the page has loaded.
