What is Image converter?

Image converter re-encodes images into the format you need using the browser’s own image engine. Convert WebP images that some apps will not open into JPG, turn PNG screenshots into lighter WebP, or make a PNG from a JPG for editing.

When to use it

  • Open a WebP image downloaded from a website in older software.
  • Convert PNG to JPG to meet an upload requirement.
  • Make WebP versions of images for a faster site.
  • Turn a BMP or GIF into a modern format.

Tips for the best result

  • JPG does not support transparency – transparent areas are filled with white or black.
  • WebP at 80% quality is a great default for the web.
  • Use PNG for logos and screenshots with sharp edges.

Limits and privacy

For animated GIFs only the first frame is converted. HEIC photos need the HEIC to JPG tool. Processing happens entirely in your browser, so your data never leaves your device and there is nothing to sign up for. Files are processed in your browser and never uploaded.

Many people who use Image converter also need HEIC to JPG or Compress image, and Resize image is one click away. Every MondayKit tool works the same way – open the page, add your input, get the result – with no account, no watermark and no upload.

Frequently asked questions

How do I convert PNG to JPG?

Add your PNG, choose JPG as the output format, set the quality and click Convert.

What happens to transparency in JPG?

JPG cannot store transparency, so transparent areas are filled with the background colour you choose – white by default.

Is WebP better than JPG?

WebP files are usually 25–35% smaller at similar quality and support transparency, but some older apps cannot open them.

Can I convert many files at once?

Yes. Add several files and download them as a ZIP.
