Why use this tool?
Base64 encoding lets you represent binary image data as plain text, which is perfect for embedding small graphics without extra HTTP requests. This tool accepts all common formats including JPEG, PNG, GIF, WebP, and SVG. Your file is processed entirely inside your browser using native Web APIs, so nothing is ever uploaded to a server. imgic never sees, stores, or transmits your images. The resulting data URI string is ready to paste directly into an img tag, a stylesheet, or a JSON payload.

Frequently asked questions
What image formats can I convert to Base64?
You can convert virtually any browser-supported image format including JPEG, PNG, GIF, WebP, SVG, BMP, and ICO. The tool reads the file locally and produces a valid Base64 data URI regardless of the source format.
Is my file private and secure?
Completely. Your file is processed 100% inside your browser using the Web APIs built into your device. Nothing is uploaded to any server — imgic never sees, stores, or transmits your images. You can even use these tools offline once the page has loaded.
Is there a file size limit for Base64 encoding?
There is no hard limit enforced by the tool. However, Base64 strings are roughly 33% larger than the original binary file, so very large images will produce extremely long strings. For practical use in HTML or CSS, images under 100 KB typically work best.
How do I use the Base64 string in my code?
Copy the full data URI string and paste it as the src attribute of an HTML img element, or use it inside a CSS url() function for background images. The string includes the MIME type prefix so browsers know how to render it.
Can I convert multiple images at once?
Currently the tool handles one image at a time. Upload a file, copy or download the Base64 output, then upload the next image. Each conversion is instant so batch workflows remain fast.
