Caveat

Data URLs can bloat HTML/CSS size for large images, so use them selectively.

Step-by-step usage

Select image — Upload PNG, JPG, SVG or WebP file.
Generate output — Tool reads file and creates Base64 data URL.
Copy value — Use output in HTML/CSS/JSON where needed.

Common pitfalls

Check the result before replacing the original input.
Watch for unit, format, encoding, and browser memory limits on large inputs.
Keep a copy of important source material until the output is verified.

Privacy and security

Browser-first by design. The tool page explains any exception before you use it.

Your input is handled in the browser wherever the tool can process it locally. EpitomeTool does not add an upload step unless a tool page explicitly says so.

Frequently asked questions

Yes, files are read with FileReader in your browser only.

A standard data URL: data:<mime>;base64,<payload>.
