Convert a WebP image into a Base64 data URL, or decode WebP Base64 back into a downloadable image.
This converter reads the original WebP bytes and represents them as standard Base64 inside a data:image/webp;base64,... URL. Decode mode reverses that byte-for-byte representation back into a WebP file.
Base64 does not compress or improve the image. It normally makes the textual representation larger than the original binary file.
The image is not re-encoded in either direction. A valid round trip preserves the original WebP bytes represented by the Base64 value.
The format check requires still-image data or an animated frame structure; a WebP header alone is not enough. This checks file structure, not every detail of the compressed image.
No. Base64 represents the same binary bytes as text, so this conversion does not recompress the WebP image.
Usually no. Base64 adds encoding overhead, so the text representation is typically larger than the source WebP bytes.
Yes. Decode mode accepts data:image/webp;base64,... as well as the Base64 payload by itself.
The decoded bytes must identify a WebP file and pass the file-size and image-structure checks. Renaming another image to .webp does not convert it.
No. Your file is processed locally in your browser without a server upload.
No. This tool preserves WebP bytes and converts only between WebP binary data and its Base64 representation.
