// Encode WebP images to Base64 strings and data URIs - lossy, lossless, alpha, and animation bytes preserved

Modern Image Payloads
Encode WebP files exactly as stored: VP8, VP8L, alpha, metadata, and animated frame data are preserved byte-for-byte.
Local Processing
The browser reads your WebP with FileReader. No upload, no server conversion, and no image bytes leave your device.
Data URI Output
Copy a ready-to-use data:image/webp;base64,... URI for HTML, CSS, email templates, JSON payloads, and offline bundles.
// FAQ - WEBP TO BASE64
Q: What is WebP to Base64 encoding?
A: It rewrites the binary bytes of a .webp file as ASCII-safe Base64 text. The encoded result can be embedded in HTML, CSS, JSON, or any text-only channel while preserving the original WebP bytes.
Q: Does Base64 change WebP quality?
A: No. Base64 is a reversible binary-to-text transform, not image compression. Lossy WebP quality, lossless WebP pixels, alpha, ICC metadata, and animation chunks remain exactly as they were.
Q: What does a Base64 WebP data URI look like?
A: A full WebP data URI starts with data:image/webp;base64,. A raw WebP Base64 payload usually begins with UklGR, which is the RIFF container signature encoded as Base64.
Q: Can I encode animated WebP to Base64?
A: Yes. Animated WebP files are encoded byte-for-byte. The animation frames and loop metadata stay in the payload, and browsers that support animated WebP can render the decoded data URI.
Q: When should I inline a WebP as Base64?
A: Inline small WebP images when a single-file HTML document, email, report, or critical-path icon is more useful than separate caching. For larger images reused across pages, a normal .webp file served from a CDN is usually better.
Q: Is my uploaded WebP sent to a server?
A: No. The page uses browser APIs to read the file locally and produce the Base64 string. Open the Network tab while converting and you will see no request containing your image.
