WebP to data URI converter.

Yes, by as much as the WebP is smaller than the PNG, typically 25 to 35%. The Base64 adds the same third to each, so the saving carries straight into the string, which matters when the image goes into a JavaScript bundle or a stylesheet.

Small UI assets that must be there at once: an icon, a logo, a placeholder. Inlined in the bundle, they load with no request, no cache rule and no offline case. Keep it to images under 10 to 15 KB.

Every current browser decodes both WebP and data URIs: Chrome, Firefox, Safari 14 and later, Edge. For older browsers, give a PNG or JPG fallback through a picture element or convert the image first.

Yes. The URI carries the WebP's bytes unchanged, alpha channel included, so a transparent WebP shows with its transparency wherever the URI is used.

For anything over 10 to 15 KB, for images that only some pages use (a file is cached on its own), and when you want a CDN to serve it. A data URI can't be cached apart from the document that holds it.

No. The browser decodes the file, a canvas does the work and the result is built on your device; the page makes no request with your image. You can load it, go offline and keep working.

Drop the file and choose the snippet in the bar: the bare URI, an img tag with the URI as its src, or a CSS background-image rule. Copy it or download it as a .txt, .html or .css file.

No. The WebP to data URI converter is free and opens without a sign-in, an account or an install.

Nothing. The WebP to data URI converter holds your input in the page's memory, so closing or reloading the tab clears it, and it saves nothing in this browser.

Up to 25 MB per file, the limit the tool states under its drop area. A larger file is refused with a plain message instead of being decoded.

No, it takes one file at a time. If you drop or choose several, only the first is used; run the tool again for the next one.

No. The text is made from the file's own bytes, unchanged, so EXIF and every other metadata field stay inside it. Nothing is re-encoded or resized.

About a third longer: Base64 writes every three bytes as four characters. The status line shows the exact character count and the overhead for your file.

Closest to the WebP to data URI converter: WebP to Base64 encoder, WebP compressor, PNG to data URI converter, AVIF to data URI converter. Each opens on its own page, free and in the browser.

The WebP to data URI converter is one of 44 in its group. The group's page, /tools/webp, lists them all.

The tool is free. Its interface is built from shadcn.io's own components (Button, Input, Slider and the rest of the registry under /ui), which come in React, Vue, Svelte and Solid. Pro adds the blocks and templates for the product around it.
