About AVIFify

Free AVIF image conversion tools that run entirely in your browser. Fast, private, and usable on any device — no sign-up, no uploads, no clutter.

Our Mission

To make the simplest, fastest, most private AVIF image tools on the web. Free for everyone, with no sign-up, no tracking, and no upload limits getting in the way.

Our Vision

A complete AVIF toolkit that anyone can reach for instantly. From single-image conversion to batch processing, format reference, and side-by-side comparisons — one place, every tool you need.

Why Choose AVIFify

Privacy First

Every conversion runs in your browser using WebAssembly. Your images never leave your device, never touch our servers, never get logged.

Instant Results

No upload queue, no server roundtrip. Drop an image in and the converted file is ready in seconds, even for large batches.

Works Everywhere

Optimised for desktop, tablet, and mobile. Modern browsers only — no app to install, no plugin to enable.

How We Build AVIFify

Browser-only, by design

Conversion that respects your files and your privacy

AVIFify was built by people who got tired of uploading images to random websites just to get a smaller file back. Every converter on this site runs locally in your browser using modern web APIs and WebAssembly — your image data is never transmitted, stored, or logged anywhere.

We use the tools ourselves every day and improve them based on what people ask for. If a converter direction is missing or a feature would help, let us know.
