Frequently asked questions
What's a data URI?▾
A self-contained image string like data:image/png;base64,iVBOR... that you can paste straight into HTML or CSS.
Is there a size limit?▾
Browsers handle up to a few MB comfortably; for very large images consider hosting instead.
Should I use Base64 images on my website?▾
For small icons and tiny graphics, yes — it saves an HTTP request. For large images, no — Base64 is 33% larger than the binary file and prevents browser caching. Use real <img> tags for anything over 5 KB.
Will the image quality drop?▾
No. Encoding doesn't recompress the image; it just changes the representation. The decoded output is bit-identical to the source.
