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 BMP to JPG

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

Frequently asked questions

How much smaller will the files be?

A BMP stores every pixel uncompressed, so the JPG is often 10 to 20 times smaller.

Will the picture look different?

JPG is saved at high quality (90%), so photos look the same. For screenshots with fine text, PNG keeps them sharper.

Can I convert many BMP files at once?

Yes. Select or drop as many as you like; several files download as one ZIP.

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.
