What happens to your image going from JPG to PNG
- A PNG can't restore detail the JPG had already dropped, but it does prevent any more loss when you re-save. The file will be larger, because PNG keeps every pixel exactly.
JPG vs PNG in brief
- JPG (or JPEG) is the photo format that works almost everywhere. Lossy compression keeps files small, but there's no transparency and each re-save throws away a little more detail.
- PNG is lossless, meaning every pixel is stored exactly, and it supports full transparency. That suits screenshots, logos and graphics perfectly, but a photo saved as PNG is often several times larger than the same shot as a JPG.
Worth knowing
- You can add as many files as you like. Bigger batches simply take a bit longer, since your own device is doing the work.
- Files with the same name get a number added (photo.jpg, photo-2.jpg), so nothing in the ZIP gets overwritten.

Questions & answers
Does changing JPG to PNG lower the quality?
No more quality is lost, because PNG is lossless. Your PNG matches the JPG exactly.
Can I do a whole batch of JPG files?
Yes. Add as many as you want; each is converted separately, and Download all bundles them into a single ZIP.
