Frequently Asked Questions
How do I convert an image to Base64?
Drop an image (PNG, JPG, GIF, WebP, or SVG) into the Image → Base64 tab. It's instantly encoded to a Base64 data URI, and you can copy it as raw Base64, a data URI, or a ready-made CSS, HTML, Markdown, or JSON snippet.
Can I decode Base64 back into an image?
Yes. Switch to the Base64 → Image tab, paste your Base64 or a data: URI, and the image renders instantly. You can then download it — the file extension is inferred from the data URI's MIME type.
Why embed an image as Base64?
A Base64 data URI lets you inline a small image directly in CSS, HTML, JSON, or an email so it loads without a separate HTTP request. It's handy for icons, email signatures, and self-contained files.
Which image formats are supported?
Any format your browser can read — PNG, JPG/JPEG, GIF, WebP, SVG, BMP, ICO, and AVIF. The MIME type is preserved in the data URI so the image decodes correctly.
Is my image uploaded to a server?
No. Encoding uses the browser's FileReader and decoding renders locally, so your image never leaves your device. That makes it safe for private images.
Should I Base64-encode large images?
Usually not — Base64 makes data about 33% larger, so it's best for small images like icons and logos. For big images, a normal file URL is more efficient.
