BMP to GIF Converter
Convert BMP files (released 1986 (Microsoft), None (uncompressed) or RLE) to GIF (Lossless (256-color palette), typically Bloated for photos, fine for short loops). Runs in your browser — no upload, no signup.

Need to turn BMP files into GIF? This tool does it in seconds, right in your browser. BMP is known for Legacy Windows tools, embedded devices, industrial scanners and GIF for Short looping animations on platforms that don't accept video, so the conversion makes sense whenever your workflow has standardised on GIF or your target platform expects it. In our sample set, BMP files came out about 90% smaller as GIF. There's no software to install and nothing is sent to a server — the fast path encodes locally and hands you the file immediately. Read on for a plain-language comparison of BMP and GIF, the settings that matter, the pitfalls to avoid, and answers to the questions people ask most about BMP → GIF.

Real BMP → GIF file sizes
We ran a fixed set of sample images through this exact converter so you can see the typical size impact before converting your own files.
| Sample image | BMP size | GIF size | Change |
|---|---|---|---|
| Photo | 192.1 KB | 70.6 KB | -63% smaller |
| Screenshot / UI | 256.1 KB | 786 B | -100% smaller |
| Logo / transparency | 256.1 KB | 2.5 KB | -99% smaller |

Best practices for BMP → GIF
Concrete settings to pick before you convert BMP to GIF.
- Always preview the GIF output before bulk-downloading — colour shifts, transparency surprises, and quality artifacts show up in the preview before they ship.
- Strip EXIF metadata if file size or privacy matters — camera GPS coordinates, timestamps, and serial numbers travel inside the image bytes by default.
- GIF is lossless, so quality settings don't apply — but you can still shave bytes by quantising the palette (pngquant for PNG, gif2webp for GIF) when the image has a limited colour count.
- Verify the alpha channel rendered as expected — premultiplied vs straight alpha and edge halos around antialiased pixels are the most common surprises when going to GIF.
- When converting to GIF (animated), confirm the frame timing matches your source — some encoders default to a fixed 100ms delay per frame instead of preserving the original timing.
- For web GIF delivery, encode in sRGB — wider colour spaces (Display P3, ProPhoto) render unpredictably across browsers and email clients.
- Re-encoding a BMP (lossless) source into another lossless format like GIF preserves every pixel, but the file size can swing in either direction with no gain in quality. If the goal is smaller files, pick a lossy target (JPEG, WebP, AVIF); if it's pixel fidelity for archival, keep the BMP original.
When NOT to convert BMP → GIF
Honest cases where this conversion is the wrong call — pick a different format or keep your BMP source.
Skip if the file is bound for print
GIF is a delivery-grade web format. Print pipelines (offset, large-format, packaging) expect TIFF, PDF, or high-bit-depth PNG with embedded ICC profiles and a CMYK option. Converting BMP to GIF for a print job will likely fail prepress checks — keep the original or convert to a print-friendly format instead.
