How to use
What is this for?
Convert common raster formats and Base64 locally in the browser—handy for small inlined images, API payloads, or inspecting data URLs.
Suggested workflow
- Click Upload and choose PNG, JPEG, GIF, or WEBP; the preview updates immediately.
- Optionally check Include data URL prefix, then click To Base64 to write results into the text area.
- Paste Base64 from elsewhere and click To image to refresh the preview (raw Base64 is treated as PNG by default).
- Use Copy Base64 to copy the current text; Clear resets upload, preview, and the text area.
Supported formats
Tips
- Large images produce very long Base64 strings and may slow the page—prefer small assets.
- If pasted text has line breaks or spaces, normalize to a single line before converting to image.
- For general text or file Base64, pair this page with the site’s dedicated Base64 encoder/decoder if needed.
