When to use this tool

  • You need a AVIF file because the destination (a website, CMS, app or printer) expects AVIF.
  • You want the best compression available today — often half the size of WEBP — ideal for hero images, large galleries and bandwidth-sensitive sites.
  • You no longer need PNG's transparency or lossless precision and want a smaller, faster file.

Best for

  • Next-gen websites
  • Large hero images
  • Bandwidth-heavy galleries
  • Sites that already have a JPG fallback

Every image you drop here is processed entirely inside your browser using the standard Canvas and File APIs. Nothing is uploaded, stored or logged on a server — you can disconnect from the internet after the page loads and the tool still works.

Quality & file size notes

  • • AVIF uses lossy compression. Quality 85–92 is visually identical to the source for almost every photo — drop below 70 and you'll start to see softness on faces, gradients and text edges.

Things to watch out for

  • — AVIF encoding is slower than JPG/WEBP. Older browsers (Safari < 16, IE) cannot display AVIF — serve a fallback for them.

More questions about this tool

Why convert PNG to AVIF?+

AVIF offers the best compression available today — often half the size of WEBP, which makes it ideal for hero images, large galleries and bandwidth-sensitive sites. PNG on the other hand is supported everywhere — the web default for non-photo images, so converting gives you a file that fits the destination better.

Will I lose quality converting PNG to AVIF?+

AVIF is lossy, so some information is compressed away. At quality 85–92 the result is visually indistinguishable from the PNG source for almost every image.

Is this PNG to AVIF converter really free?+

Yes — completely free, with no sign-up, no watermark and no upload limit. The site is supported by lightweight ads so every tool stays free.

Are my PNG files uploaded anywhere?+

Every image you drop here is processed entirely inside your browser using the standard Canvas and File APIs. Nothing is uploaded, stored or logged on a server — you can disconnect from the internet after the page loads and the tool still works.

Frequently Asked Questions

Do these tools run in my browser?
Yes — where supported, every compressor, converter, resizer and cropper runs entirely in your browser using the Canvas API and WebAssembly. Your files are processed on your own device, not on a remote server. A small number of edge cases (very large PDFs, some HEIC variants on older browsers) may fall back to a slower path, but for the priority tools the work happens locally.
Do I need to sign up or create an account?
No. There is no signup, no email gate and no free trial. Open any tool, drop your files in and download the result. You can use ImageToAnything in private/incognito mode without any account at all.
How is my privacy handled?
Privacy-first by design. For browser-based tools, your images never leave your device — they are not uploaded, not logged and not retained. We do not add a watermark, and re-encoding strips EXIF and GPS metadata so personal details aren't carried into the output.
Is this image converter free?
Yes — ImageToAnything is 100% free with no limits, no sign-up, and no watermarks. The site is supported by unobtrusive advertising, so every free private image tool stays completely free to use.
Are my images uploaded to a server?
No. All conversions happen locally in your browser using the Canvas API and WebAssembly. Your images never leave your device, are never transmitted over the network and are discarded from memory as soon as you close the tab.
Can I convert multiple images at once?
Absolutely. Drop in as many images as you'd like and use Convert All. You can download them individually or download every result as a single ZIP. The batch runs in parallel for speed, and you can pause, resume or clear the queue at any time.
What image formats are supported?
We support JPG, PNG, WEBP, BMP, GIF, HEIC, HEIF, AVIF, SVG, TIFF and PDF as inputs, and JPG, PNG, WEBP, BMP, GIF, AVIF and PDF as outputs. See the full image format guide for which format to choose.
Does it work on mobile devices?
Yes — the converter is fully responsive and works on any modern browser on phone, tablet or desktop, including iOS Safari and Android Chrome. You can convert photos straight from your camera roll.
Can I reduce image size?
Yes. Use the Quality slider for lossy formats (JPG, WEBP, AVIF) and the Resize option to shrink dimensions. There are also dedicated compressors that target a specific file size such as 100 KB, 200 KB or 1 MB.
