AVIF image compression
Your image is converted to the AVIF format using a browser-based WebAssembly encoder. The compressor searches for a practical quality and resolution combination close to your selected file size.
Images are processed locally in your browser using WebAssembly. Your image is not uploaded to the server.
AVIF image compressor
Compress AVIF images and reduce image file size
AVIF is a modern image format designed to provide efficient compression while maintaining useful image quality. If you have large AVIF files, this tool can help reduce their file size by adjusting image quality and dimensions.
You can also use this AVIF compressor to convert common image formats such as JPG, JPEG, PNG, WebP and GIF into AVIF. Set a target size in KB and the browser-based compressor searches for a suitable result.
Because processing happens on your device, your selected image does not need to be uploaded to a remote compression server. This makes the tool useful when you need a quick image size reduction without creating an account.

FAQ
AVIF Compressor frequently asked questions
An AVIF compressor reduces the file size of an image while encoding the result as AVIF. This tool can also convert supported image formats such as JPG, PNG and WebP to AVIF.
Yes. Select an existing AVIF image, choose your target size and run the compressor. The result is generated locally in your browser.
Yes. A supported JPG or JPEG image can be selected and converted to AVIF using the compressor.
Yes. Supported PNG images can be converted to AVIF. The resulting file can be significantly different in size depending on the image content and selected settings.
Yes. If your browser can decode the WebP source, it can be processed and encoded as AVIF.
You can enter 100 KB as the target. The compressor searches for a result close to that size. The final size depends on the source image, dimensions, compression settings and AVIF encoding.
The compressor attempts to get close to the selected target, but an exact byte count cannot be guaranteed for every image because image content responds differently to compression.
No. The compression process is designed to run locally in your browser using WebAssembly. The selected image does not need to be uploaded to the Laravel application.
Yes. The AVIF encoder generates an AVIF image and the downloaded file uses the .avif extension.
The browser needs to initialise the WebAssembly AVIF encoder. This startup step can make the first compression slower than subsequent operations.
Not necessarily. The resulting size depends on the original format, image content, dimensions and encoding settings. Some already-optimized images may not become substantially smaller.
Lossy compression can reduce image detail. The compressor uses quality and resolution adjustments to balance visual quality with the selected file-size target.
Yes. It can be useful for preparing smaller AVIF assets for websites, provided the target browsers and your website implementation support AVIF.
Yes. The tool is available to use without an account, watermark or paid compression subscription.
