Why use this converter

Privacy First

Unlike other converters, we don't upload your files to our servers. All processing is done client-side.

Runs in the Browser

Each image is converted with the Canvas API on your device, one file at a time.

Modern Formats

Stay ahead of the curve with support for next-gen formats like WebP and AVIF for better web performance.

Pixel Safety Cap

There is no daily quota. Images wider or taller than 16,384 pixels, or over 80 million pixels, are skipped so the tab stays stable.

Batch Queue

Add several images, convert them in order, then download each file or a ZIP of the results.

Quality You Set

The slider affects JPEG, WebP, and AVIF. PNG output stays lossless. Animated files keep the first frame only.

Quality & Compatibility Strategy

WebP to AVIF works best when you start near quality 45-62 and validate with real assets.

Transparency can be preserved through this conversion route. This converter exports one frame. Animated WebP files become a still AVIF image, even when AVIF can store animation. Expect notably smaller files in most real-world images.

Useful for next generation compression that often beats WebP in file size
