Image to Base64 client-side ?
How to use Image to Base64This tool converts an image into a Base64 data URI: a long text string that represents the image and can be pasted straight into CSS (background-image) or an <img> tag, with no separate file and no extra HTTP request. Handy for small icons, HTML emails or self-contained components. You also get ready-to-copy CSS and <img> snippets.
Note: Base64 encoding increases size by about 33%, so keep it for small images; beyond that, a regular file is better. The image is read and encoded locally by your browser (FileReader) and is never sent to a server.

Frequently asked questions
When should I use a Base64 image?
For small images (icons, logos), HTML emails, or to avoid a network request. For large images, a regular file stays lighter and cacheable.
Does Base64 increase the size?
Yes, by about 33% versus the binary file — the trade-off for embedding the image as text.
Is my image uploaded to a server?
No. The conversion happens entirely in your browser; the image never leaves your device.
