Image to Base64

1. Upload a PNG, JPG/JPEG or WebP image.
2. Review name, type, original size and detected extension.
3. Copy the plain Base64 or the full Data URL.
4. Download the result as TXT if you need to save it.

• Embed a small image in HTML, CSS or JSON.
• Prepare a Data URL for frontend testing.
• Share a Base64 payload without a backend.

• Base64 usually takes more space than the original binary file.
• It does not compress, optimize or convert the image format.
• Large images generate long text that is hard to inspect manually.

Processing happens in your browser — we don't upload your files.

• A file that is not PNG, JPG/JPEG or WebP.
• A damaged image or one the browser cannot read.
• A file too large to process reliably.

• Uses FileReader.readAsDataURL.
• Plain Base64 is obtained by removing the Data URL prefix.
• Supported MIME types are image/png, image/jpeg and image/webp.
