How The Converter Works

The browser reads the GIF file as raw bytes and encodes those bytes into Base64 text.

You can keep only the Base64 payload or include the full `data:image/gif;base64,...` prefix for embedding.

For a JSON field that expects Base64, choose Raw Base64 and copy the encoded text.

For an HTML image source, choose Data URL to include the GIF type and encoded image together.

For a CSS background image, use the Data URL as the value inside url(...).

To save the encoded text for later, choose the output mode you need and select Download Text.

Yes. Base64 encoding preserves the original GIF bytes exactly, including animation data.

Some destinations want a full embeddable string rather than just the Base64 payload.

Yes, though large files can create very large text output that is harder to copy and render.

No. Base64 text is larger than the original GIF bytes; encoding does not compress the image.

Base64 is an encoding, not an image conversion, so the original GIF format is preserved.

A data URL includes a prefix as well as the Base64 payload. Large GIFs produce long strings in either mode.

The conversion runs entirely in the browser without uploading the file to a server.
