Frequently asked questions

When should I embed images as Base64?+

Only for small images (under ~10 KB) like icons β€” it saves an HTTP request. Larger images are better served as files since Base64 adds ~33% size overhead.

Are my images uploaded anywhere?+

No β€” conversion happens locally in your browser using the Canvas API. Your images never touch a server, so private photos stay private.

Is my data private?+

Yes. The tool runs entirely in your browser β€” nothing you paste or type is uploaded to a server.
