Base64 to WebP Converter

Base64 to WebP, explained

WebP is a modern format that often beats both PNG and JPG on file size while keeping quality and transparency. This converter detects PNG, JPG, GIF, WebP or SVG Base64 input and exports a real .webp file in your browser.

When to choose WebP

• Smaller files for the web. WebP typically compresses better than PNG or JPG.
• You need transparency or animation. WebP supports both.
• Modern browsers only. All current browsers support WebP; very old ones may not.

What you can paste

• A full data URI — for example, data:image/png;base64,iVBOR... or data:image/webp;base64,UklGR....
• A bare Base64 body — the source format is detected automatically before conversion.

This page re-encodes through canvas

Unlike the generic Base64 to image decoder, this page exports image/webp at quality 0.9 via canvas.toBlob. A JPEG or PNG source becomes a new WebP; it is not a lossless round-trip. Animated GIF or WebP input is flattened to the first frame the browser paints. Alpha from PNG is kept. If you only need the original bytes, use the generic decoder.

Private by design

Decoding uses the browser's native image handling — the string is turned into an image element locally and never sent anywhere. Safe for confidential assets.
