Questions
Is my image uploaded?
No. Everything runs in your browser, so your image never leaves your device.
Why is the Base64 bigger than the file?
Base64 encoding adds about 33% overhead. Use data URIs for small images and icons.
Which formats work?
Any image your browser can read, including PNG, JPG, WebP, GIF, SVG, and AVIF.
