Free Image Converter

Convert images between WebP, JPEG and PNG in your browser. Useful for getting old JPEGs and PNGs into WebP, which is usually the smallest of the three.

Runs entirely in your browser — nothing is uploaded

Drop images here, or choose filesUp to 20 images at once. JPEG, PNG, WebP, GIF, AVIF or SVG, up to 25 MB each.

Your images stay on your device. Every one of these image tools runs entirely in your browser — nothing is uploaded, nothing is stored, and there is no server involved. You can check for yourself: disconnect from the internet after this page loads and the tool still works.

Converting cannot recover quality that was already lost. A JPEG saved as PNG becomes a larger file containing exactly the same visible detail, compression artefacts included. Convert from the highest-quality original you have.

What this tool does not do: Converts to WebP, JPEG and PNG — the formats browsers can encode. AVIF encoding is not available in browsers, so it can be read here but not written.

How to use this tool

Drop the images you want to convert.
Choose the output format.
Convert, check the result, and download.

What is Image Converter?

WebP is the practical default for the web today. It is supported in every current browser, handles both photographs and transparency, and is typically 25 to 35% smaller than an equivalent JPEG.

Format choice is mostly about content, not preference. Photographs compress well with lossy formats. Logos, icons and screenshots — large flat areas with sharp edges — look wrong in JPEG and belong in PNG or, better, SVG.

Best practices

Use WebP for photographs and most content images.
Use PNG when you need transparency and WebP is not an option.
Use SVG for logos and icons; converting one to a pixel format loses its main advantage.
Convert from the highest-quality original you have, not from an already-compressed copy.

Frequently asked questions

Is WebP safe to use now?

Yes. Every current browser supports it, including Safari since 2020. If you support genuinely ancient browsers, serve a JPEG fallback with the picture element.

Why can it not convert to AVIF?

Browsers can display AVIF but cannot encode it — the encoder is not exposed to web pages. Doing it here would mean uploading your image to a server, which these tools do not do. Squoosh runs an AVIF encoder compiled to WebAssembly if you need one.

Will converting improve quality?

No. Conversion cannot recover detail that was already discarded. A JPEG saved as PNG is simply a larger file with the same visible artefacts.
