Convert image format online — free and private
Convert PNG to AVIF online for free — no upload, no signup, all in your browser.
Convert between JPG, PNG, WebP and AVIF directly in your browser. Great for switching to modern formats like WebP or AVIF for smaller files, or back to JPG/PNG for maximum compatibility.
All processing happens locally in your browser — your images are never uploaded.
Conversion notes
Starting from a PNG keeps every pixel intact and preserves transparency, so the result will be larger when converted to a lossy format. Converting to AVIF yields the smallest file of all, though you should confirm that your audience's browsers and software support it.

Frequently asked questions

No — there is no signup and no account required. Just drop your image and go.
Why is “no upload” better than a typical online image tool?
Most “online” compressors and converters upload your file to a remote server, process it there, then send the result back. That means a copy of your photo can sit on someone else’s disk, appear in their logs, and be subject to their retention policy. ImagElite runs WASM codecs inside your browser tab — the bytes never leave your device — so private photos, screenshots with personal data, and work assets stay local.
How does in-browser WASM processing work?
ImagElite ships modern image codecs compiled to WebAssembly (jsquash). After you drop a file, the codec runs on your CPU in the browser sandbox: decode → transform → encode → download. Large codec modules load on demand and can be cached by the service worker, so repeat visits stay fast and the tools also work offline as a PWA.
Which format should I pick for the web?
Photos: WebP or AVIF when you can, JPG when you need max compatibility. Graphics with transparency: PNG or WebP. Screenshots with text: PNG or lossless WebP. Use the format guide on this page and the dedicated pair pages for each direction.
