Image Compressor

AVIF converter

Convert JPG, PNG and WebP images to AVIF, the newest mainstream web image format, which is usually smaller than WebP or JPG at similar quality. The conversion runs in your browser using its own encoder, and not every browser can create AVIF files yet (Chrome could not in our tests). The tool checks before converting. If AVIF isn't available it selects WebP and tells you, rather than saving a PNG with an .avif name.

Your images stay on your device. Nothing is uploaded.

Supported formats and how processing works

Files you can open
JPG, PNG and WebP, up to 25 MB each. iPhone HEIC/HEIF photos open only in the HEIC to JPG converter. PDFs open in the PDF to image tool.
Files you can save
JPG, PNG and WebP. WebP and AVIF output depend on your browser's encoder (in our tests, Chrome could not create AVIF). If your browser can't produce the format you picked, the tool tells you instead of saving a different format under the wrong file extension.
Where the work happens
In your browser, using its built-in canvas image encoder. The tools contain no upload step, so your image is not sent to our server. Our analytics (Google Analytics with Consent Mode) records usage numbers such as file size and format, never the image itself.
What changes in the file
The image is re-encoded, so camera metadata (EXIF, including GPS) is not carried over. JPG has no transparency, so transparent areas become white. PNG is lossless: to shrink one, reduce its dimensions or convert it to WebP.
