Base64 is a free in-browser image encoder: drop JPEG, PNG, GIF, WebP, SVG, and other common formats, optionally compress, resize, or convert, then copy an HTML <img> tag, a CSS background-image rule, or the raw data URI. Images never leave your browser. Installable as a PWA.
Context
Embedding small images in HTML, CSS, or email templates should not mean uploading photos to a third-party encoder. Designers and developers need a private, local path from file to data URI.
Approach
The UI is a drop zone with optional compress, resize, and format conversion. Encoding, compression, and resizing all run in the tab. Output is a ready HTML img tag, a CSS background-image declaration, or raw Base64 — one click to copy. Limits: up to 20 files, 25 MB each.
Result
Open https://base64.beoops.com, drop images, copy the snippet you need. No account. Add to home screen on Android or iOS Safari; the shell still opens offline.
