Why your files stay on your device

Nothing is uploaded

Most online PDF sites send your file to their servers. PDFMoss does the work inside your browser, so there is nothing to intercept, store or leak.

No limits on uses

There are no daily caps because there are no servers doing the work. Use any tool as often as you like.

Works on your phone

Every tool works on iPhone and Android: pick photos from your gallery and sign with your finger.

Original quality, works offline

Pages and images keep their quality, and once you install the app the tools work without an internet connection.

How to convert PNG to JPG

  1. Drop your PNG files on the page or choose them from your gallery.
  2. JPG is already selected as the output.
  3. Click Convert and download the image or ZIP.

Frequently asked questions

Why convert PNG to JPG?

JPG files are usually much smaller, which helps with email attachments and upload limits.

What happens to the transparent background?

It becomes white, because JPG does not support transparency.

Will the image look worse?

JPG is saved at high quality (90%), so photos look the same. Screenshots with small text may look slightly softer than the PNG.

Are my files uploaded to a server?

No. PDFMoss processes files inside your browser. The counter at the top of the page shows 0 B uploaded because nothing is sent.

Is PDFMoss free?

Yes. Every tool is free to use with no sign-up and no watermark on your files.
