Frequently asked questions
What’s a data URL good for?
Embedding images directly in HTML/CSS without separate files. Useful for emails, small icons, single-file apps, and offline-first pages.
Is my image uploaded anywhere?
No. The browser reads the file locally via FileReader. Nothing leaves your machine.
Is there a size limit?
Only your browser memory. But Base64 increases file size ~33%, so it’s best for small images.
