What is an Image to Base64 Converter?
An Image to Base64 Converter turns an image file into Base64 text that can be copied into code, data files, HTML, CSS, or API payloads. Base64 Only is the raw encoded text, while a Data URL adds the data:image prefix needed for direct browser embedding. This tool reads the image in your browser and keeps the file on your device during normal use.

Frequently Asked Questions
Quick answers to common questions about using this tool.
Is my image uploaded to PotatoTools? +
No. The image is read and converted in your browser during normal use. It is not uploaded or stored by PotatoTools.
Why is Base64 larger than the original image? +
Base64 text is usually about one third larger than the original binary image file. The size comparison shows this before you copy.
What output format is copied by default? +
The default copy format is Base64 Only, which is the raw encoded image text without the data:image prefix.
When should I use Data URL, HTML, or CSS output? +
Use Data URL when a browser needs the full data:image prefix. Use HTML img or CSS background-image when you want copy-ready markup or CSS.
Which image formats are supported? +
The tool supports PNG, JPG, JPEG, WebP, and GIF files up to the shared PotatoTools upload limit.
Can I paste an image from my clipboard? +
Yes. When the browser provides an image file on the clipboard, you can paste it into the tool and convert it directly.
Should I use Base64 for large images? +
Usually no. Base64 is useful for small embedded assets, quick tests, and code snippets. Normal image files or URLs are usually better for large images.
