About JPG
JPG (JPEG) is the most widely supported photo format. It uses lossy compression, which keeps files small, and it opens everywhere. It doesn’t support transparency.
About PNG
PNG is a lossless format: it keeps every pixel exactly and supports transparency. It’s ideal for screenshots, logos and graphics, but photos saved as PNG are large.
Frequently asked questions
Are my photos uploaded?
No. The conversion happens entirely in your browser, on your own device. Your images are never sent to our servers, so it also works for private photos.
Will converting JPG to PNG reduce quality?
No. PNG is lossless, so the PNG keeps every pixel of the decoded JPG image. The file may be larger.
Can I convert several JPG files at once?
Yes. Select or drop as many files as you like, then download them one by one or all together as a ZIP file.
