One converter for everyday image formats

Different jobs need different formats: JPG for photos and forms, PNG for crisp graphics and transparency, WebP for small, fast-loading website images. This converter reads JPG, PNG, WebP, GIF, BMP, AVIF and more, and writes whichever of the three you choose.

Convert many files at once, adjust the quality for JPG and WebP, and pick the colour that replaces transparency when converting to JPG. Everything is processed on your device.

Tips and good to know

  • Animated GIFs are converted using their first frame. To keep every frame, use the GIF Splitter.
  • HEIC photos from iPhones only open in browsers that support HEIC (currently Safari). Elsewhere, export them as JPG from your phone first.
  • For vector output, use PNG to SVG; to rasterise vectors, use SVG to PNG.

Frequently asked questions

Can I convert WebP to JPG?

Yes. Add the WebP file, choose JPG and convert. Transparent areas are filled with the background colour you pick.

Is WebP better than JPG?

For the web, usually yes: WebP files are typically 25–35% smaller at the same quality and support transparency. JPG is still more widely accepted by upload forms.

Does converting reduce quality?

PNG output is lossless. JPG and WebP are lossy, but at 85–90% quality the change is hard to spot.

Are my images uploaded?

No. Conversion happens entirely in your browser.
