About Image to Base64
Working with images online usually means uploading them to a stranger's server and hoping for the best. Image to Base64 avoids that entirely. Encode images to Base64 data URLs for inline embedding in HTML, CSS, JSON or emails.
Your images are processed locally in the browser using the Canvas API. Nothing is uploaded, nothing is stored, and you can drop in private photos, screenshots or design mockups with confidence.

Frequently asked questions
Are my images uploaded anywhere?
No. Images are processed in your browser using the Canvas API and never leave your device.
What formats does Image to Base64 support?
All common web image formats — JPG, PNG and WebP — and SVG where relevant.
Is there a file-size limit?
There's no hard cap, but very large images may use a lot of memory. Try compressing first if needed.
