What you bring, what you leave with.

Source.avif

AVIF

AVIF is the newest open image format. It delivers smaller files than WebP at the same quality — often 30-50% smaller than JPG. Supported by all modern browsers.

Target.webp

WebP

WebP is a modern Google-developed format that beats JPG and PNG on file size at the same quality. Supports both lossy and lossless modes plus transparency.

On the matter

Why convert AVIF to WebP.

WebP files are typically 25-35% smaller than AVIF at visually identical quality, which makes them the modern default for the web. Converting AVIF to WebP reduces page weight, improves Core Web Vitals, and shortens load times — especially on mobile.

The procedure.

  1. 01Open this page in any modern browser.
  2. 02Drop a .avif file onto the zone above, or click to pick.
  3. 03Adjust quality if needed.
  4. 04Download your .webp. Nothing is uploaded.

Correspondence

Letters to the editor.

Q.01How do I convert AVIF to WebP?+
A.01

Drop your AVIF file onto the converter above (or click to pick one), then hit Convert. Your WebP download starts the moment the encoder finishes — usually under a second. Nothing leaves your device.

Q.02Is converting AVIF to WebP lossless?+
A.02

No. WebP uses lossy compression by default. You can tune the quality slider to trade file size for fidelity. Quality 90 is a good default that beats most online tools.

Q.03Will my AVIF files be uploaded to a server?+
A.03

No. Pixelmint runs the entire conversion in your browser using the Canvas API. Your image bytes never touch our servers, which is why this is safe for confidential screenshots, IDs, and proprietary artwork.

Q.04Is there a file size limit?+
A.04

There's no hard limit, but very large images (over ~50 megapixels) can be slow on low-RAM devices because everything happens locally. Most browsers cap canvas size around 32,767 pixels per side.

Q.05Does it cost anything?+
A.05

No. AVIF to WebP conversion is free, unlimited, and has no watermarks, signups, ads on the file, or hidden tiers.
