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 built-in check verifies the WebP container signature and chunk structure. It requires actual still-image chunks such as VP8 or VP8L, or a valid animated frame structure, rather than treating VP8X by itself as image data.
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.
After decoding, the tool checks the RIFF container signature, confirms the RIFF size matches the actual byte length, and verifies that the container includes actual still-image data such as VP8 or VP8L, or a valid animated frame structure.
No. The conversion uses browser FileReader, Blob, and object URLs, so the file can be processed locally in the page.
No. This tool preserves WebP bytes and converts only between WebP binary data and its Base64 representation.
