GIF to BMP
Decode GIF images into uncompressed bitmaps.

Several files at once, up to 25 MB each. Converted to BMP in your browser — nothing is uploaded.

GIF to BMP Converter
Turn GIF images into Windows bitmaps in your browser. The GIF is decoded by the browser, then a small encoder writes an uncompressed .bmp file — either the universal 24-bit format or a 32-bit bitmap with alpha. Everything happens locally; no file is uploaded.
Where GIF to BMP is useful
GIF is everywhere on the web, but many devices and older programs cannot decode LZW-compressed palettes. A bitmap is the lowest common denominator:
- Microcontroller projects — Arduino, ESP32, and Raspberry Pi Pico libraries for TFT, OLED, and e-paper screens commonly load 24-bit BMP files from an SD card.
- Boot and splash screens in routers, 3D printers, and car head units.
- Legacy Windows applications and development tools that only import bitmaps.
- Pixel-level analysis, where a raw, uncompressed layout is easiest to read from code.
Choosing 24-bit or 32-bit
24-bit is the safe default: three bytes per pixel and a classic 40-byte header understood by virtually every reader. Since GIF transparency becomes a solid background in this mode, set the background color to match your display — black is often right for small screens. 32-bit keeps transparency through an alpha mask in a BITMAPV4HEADER, which modern editors and engines read correctly.
Size and frames
A bitmap stores every pixel uncompressed, so a 400×300 GIF of 30 KB becomes roughly 360 KB at 24-bit. Animated GIFs are reduced to their first frame. If the target device has a tiny screen, resize the GIF first to save memory.
To convert the bitmap back, use BMP to GIF, or turn it into a modern lossless file with BMP to PNG.
Frequently Asked Questions
Can I keep the GIF transparency in the BMP?
Choose the 32-bit option: transparent GIF pixels get alpha 0 in the bitmap. With 24-bit, transparent pixels are filled with the background color you pick.
What happens to animated GIFs?
Only the first frame is converted. A bitmap holds a single image; split the animation first if you need every frame.
Why would I need a bitmap from a GIF?
Common reasons are microcontroller displays, older Windows programs, and game or firmware tools that only read uncompressed BMP images.
