Select images

Files to convert

Add one or more images. JPEG, PNG, static GIF, WebP and AVIF are supported.

Images are transferred to our server only for conversion and deleted immediately after the download.

Output

Choose WebP, AVIF or both formats. The original file names are retained.

Required formats

Automatically choose the smaller file

Ideal when the smallest file matters more than a fixed extension. We compare WebP and AVIF and return only the smaller version of each image.

WebP

The safe recommendation when you are unsure: broad support in browsers, CMS platforms and other applications.

AVIF

Often produces especially small files. Suitable when your target systems reliably support the newer format.

Reliable processing

Available orientation metadata is taken into account so images do not appear accidentally rotated or mirrored after conversion.

For each conversion, you decide whether to receive WebP, AVIF or both modern image formats.

A single result downloads directly. Multiple images or both formats are organised in a ZIP archive.
