Image to Base64
Convert images to Base64 data URIs in your browser. No upload. Copy the result for use in HTML or CSS.
Select an image and get a Base64 data URI you can paste into HTML, CSS, or prototypes. The file never leaves your device.
How to use this tool
- Choose an image file.
- Wait for the encoded output to appear.
- Copy the data URI or raw Base64 as needed for your stack.
Tips
- Data URIs increase HTML size—fine for tiny icons; avoid huge photos inline.
- For production sites, prefer hosted files or a CDN for large assets.
- After resizing, you can still encode—try Image resizer first for smaller payloads.

FAQ
Is Base64 smaller than the file?
No. Base64 is roughly ~33% larger than raw binary—trades size for embeddability.
Can I use this for SVG?
If the tool accepts SVG and your browser loads it, yes. Complex SVG may be easier to inline as markup instead of Base64.
Does this upload my image?
No. Encoding runs locally in your browser.
