How to convert PNG to JPG

  1. Add your PNG images — up to 100 at a time.
  2. Keep the default quality, or adjust it for a smaller or sharper JPG.
  3. Click Convert and download your JPG files (a ZIP when there are several).

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 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 changes when you convert PNG to JPG

JPG is lossy, so fine detail is simplified to save space; the quality setting controls the trade-off. JPG can't store transparency, so transparent areas are filled with a colour you choose (white by default). Expect a smaller file than the PNG in most cases.

Does converting PNG to JPG reduce quality?

JPG is lossy, so some fine detail is traded for a much smaller file. Use a higher quality setting to keep more.

Will the JPG be smaller than the PNG?

Usually, yes — JPG typically stores the same content in less space. The result screen shows the before and after sizes.

Can I convert several PNG 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.
