Frequently asked questions
When should I use a Base64 image?+
Inlining works best for small, frequently used images like icons and logos, where saving a network request outweighs the ~33% size increase Base64 adds.
Why is the Base64 bigger than the file?+
Base64 encoding increases size by about 33%, because it represents binary data using only text characters. For large images this trade-off is usually not worth it.
Is my image uploaded?+
No. Encoding happens entirely in your browser, so your image stays on your device.
Is it free?+
Yes. It is completely free, with no sign-up and no watermark.
