What changes when you convert JPG to PNG
- Converting to PNG can't bring back detail the JPG already lost, but it stops any further loss from re-saving. Expect a bigger file – PNG stores every pixel exactly.
About JPG and PNG
- JPG (also written JPEG) is the most widely supported photo format. Its lossy compression keeps photos small, but it has no transparency and loses a little detail every time it's re-saved.
- PNG is a lossless format: it keeps every pixel exactly and supports full transparency. That makes it ideal for screenshots, logos and graphics, but photos saved as PNG are often several times bigger than the same photo as a JPG.
Good to know
- There's no limit on the number of files. Large batches just take longer, because your own device does the work.
- Duplicate names get a number added (photo.jpg, photo-2.jpg) so nothing in the ZIP is overwritten.
