Why convert JPG to PNG?
JPG is everywhere, but it cannot store transparency and its compression is decades old. PNG is lossless and supports transparency, which makes it ideal for graphics, screenshots and further editing.
What changes when you convert JPG to PNG
- PNG files are usually larger than JPG files, because PNG stores the image with less (or no) lossy compression.
- PNG is lossless: every pixel of the decoded image is preserved exactly.

JPG to PNG: questions & answers
Is converting JPG to PNG free?
Yes, completely free with no sign-up, no watermark and no daily limit.
Will I lose quality converting JPG to PNG?
No. PNG is lossless, so the converted image keeps every pixel exactly as it was decoded from the JPG file.
Can I convert multiple JPG files at once?
Yes. Drop as many files as you like; they are converted in parallel and can be downloaded individually or as a single ZIP.
Are my JPG files uploaded?
No. The conversion runs locally in your browser, so your images never leave your device.
Does it work on iPhone and Android?
Yes. The converter works in current versions of Safari, Chrome, Firefox and Edge on phones, tablets and computers. Very large images may exceed the memory available to mobile browsers.
Is JPG the same as JPEG?
Yes. .jpg, .jpeg and .jpe are different extensions for exactly the same format. You can rename one to the other without converting.
