Frequently asked questions

How do I paste an image from clipboard?

Copy any image to your clipboard (e.g. screenshot with Ctrl+Shift+S, or right-click → Copy Image), then press Ctrl+V anywhere on this page. The image will be detected and converted automatically.

What is the difference between Data URL and Raw Base64?

A Data URL includes the mime-type prefix, e.g. data:image/png;base64,iVBOR…. Use this for embedding directly in HTML <img src="…"> or CSS. Raw Base64 is just the encoded string without the prefix — use this for APIs or storage that handle the mime type separately.

Can I import an image from a URL?

Yes — click the "Import from URL" tab and paste any public image URL. If the host blocks CORS, the request is automatically retried via multiple proxies. You can also share a shareable link with the ?import=<url> query parameter.

Is there a file size limit?

Yes — 10 MB per file. Base64 output will be roughly 33% larger than the original (e.g. a 1 MB PNG → ~1.37 MB Base64 string). The character count and decoded size estimate are shown below the output field.

Can I also convert Base64 back to an image?

Yes — use the Base64 → Image tool. Paste any Base64 string or Data URL and it auto-converts with a preview and download button.
