How to convert JPG to PNG

  1. Add your JPG images — up to 100 at a time.
  2. Nothing to set: PNG is lossless.
  3. Click Convert and download your PNG files (a ZIP when there are several).

What is JPG?

JPG (JPEG) is the most widely supported photo format. Its lossy compression is tuned for photographs, so files are small and open everywhere — but it can't store transparency, and every re-save loses a little detail.

What is PNG?

PNG is lossless: it keeps every pixel exactly and supports transparency. That makes it ideal for screenshots, logos and graphics, while photos saved as PNG are usually several times larger than a JPG.

What changes when you convert JPG to PNG

PNG keeps exactly what's in the JPG — converting can't bring back detail the JPG already lost, and the file usually gets bigger. Expect a larger file than the JPG in most cases.

Does converting JPG to PNG reduce quality?

No — PNG is lossless, so everything in the JPG is kept exactly.

Will the PNG be smaller than the JPG?

Usually not. PNG trades size for exact quality, so expect a larger file. The result screen shows both sizes.

Can I convert several JPG files at once?

Yes — up to 100 files of 100 MB each in one go. Several results download together as a ZIP.

Are my images safe?

Yes. Your images are only used to create your result — they’re never shared and never used to train AI.
