How to convert BMP to GIF

Choose a BMP, optionally resize it, and download a palette-based GIF created locally.

Select an image from your device or drag it into the upload area.

Resize the image if you need different output dimensions.

Review the preview and file size, then save the converted image.

This free online BMP to GIF converter includes the following controls and output tools:

Private browser conversion. The image is processed locally and is not uploaded.
Custom dimensions. Set an exact width and height, lock the aspect ratio, and prevent accidental enlargement.
Single-frame palette output. Create a still GIF with up to 256 colors and one-bit transparency, without a quality slider.
Before-and-after preview. Review the original and converted image, output dimensions, format, and file size.
File-size comparison. See the original and converted sizes and the percentage change.
Custom filename. Rename the converted file before downloading it.
Metadata-free export. The newly encoded GIF does not copy source metadata.

GIF can be smaller than an uncompressed BMP and may be required by older systems.

The 256-color limit suits simple graphics better than photographs. PNG is a stronger lossless choice for full-color still images.

The bitmap is quantized to a palette of up to 256 colors, which can cause banding in gradients.

The output contains one frame and does not copy BMP metadata.

Is this BMP to GIF converter free?

Yes. Convert one BMP at a time.

Will the GIF animate?

No. It contains one still frame.

Why do colors change?

GIF is restricted to a 256-color palette.

Can I reduce the size?

Resize the dimensions to reduce pixel count.

Is my BMP uploaded?

No. Conversion happens in your browser.
