Frequently asked questions
When should I use Base64 images?
For tiny icons embedded in CSS/HTML or emails. Base64 is ~33% larger than the file, so keep big images as normal files.
Is my file uploaded to a server?
No. This tool runs entirely in your browser. You can open your browser's network tab and verify no request carries your file.
