Converts GIF files to BMP format — simple animations, memes, and images on platforms that support animated GIFs natively to legacy software compatibility, raw pixel data transfers, and simple image processing tasks. All conversion happens locally in your browser with no file size limits.

WebP to BMP output is not produced here — WebP input decodes, but Canvas cannot encode BMP, so conversion fails locally. Convert WebP to PNG/JPG/WebP instead — local, unlimited saves.
HEIC to BMP output is not produced here — HEIC input decodes via heic2any, but Canvas cannot encode BMP, so conversion fails locally. Convert HEIC to PNG/JPG/WebP instead — local, unlimited saves.
AVIF to BMP output is not produced here — AVIF input decodes, but Canvas cannot encode BMP, so conversion fails locally. Convert AVIF to PNG/JPG/WebP instead — local, unlimited saves.
Convert animated GIFs to modern WebP or WebM formats with transparency support — ~10x smaller files. Shrink GIFs dramatically for modern web use — local conversion, unlimited saves.
Design simple logos with text, tagline, and 5 preset icons on canvas — export PNG/SVG. Draft startup marks in an afternoon — local Canvas work, unlimited saves.
GIF (Graphics Interchange Format) uses lossy (limited to 256 colors) encoding and is best for simple animations, memes, and images on platforms that support animated GIFs natively. BMP (Bitmap Image File) uses uncompressed encoding and excels at legacy software compatibility, raw pixel data transfers, and simple image processing tasks. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Canvas cannot encode BMP, so the run ends in Conversion failed with no file written. Convert GIF to PNG, JPG, or WebP for a working download.
Moot — no BMP is emitted from GIF input. Convert GIF to PNG for exact pixels instead.
For GIF sources: PNG for exact pixels, JPG for photos at fixed 0.92, or WebP at 0.85 — every one encodes locally with unlimited saves.
No — the attempt runs locally in your browser and fails before any save. Local-tool downloads stay unlimited.
BMP to GIF
Convert BMP bitmaps to GIF in your browser — each BMP still encodes to a single-frame GIF locally via the bundled gif.js worker. Stills-only output flattens transparency to white, and downloads are unlimited since nothing is uploaded.
Bulk Image Format Converter
Convert image batches between JPG, PNG, WebP, and AVIF outputs (JPEG/PNG/WebP/AVIF/HEIC/HEIF/GIF/BMP/ICO/SVG inputs; HEIC via heic2any, SVG rasterized at intrinsic size or 1024px fallback) with a quality slider (10–100, default 80). Pair pages (?from/?to) preset the output. Flat ZIP renamed per file — local, 5-file guest batches, 25 signed-in, 500 Pro.
Batch Image Converter
Convert a batch of images to one output — JPG, PNG, or WebP — at quality 10–100% (default 80%), capped at 4096px longest side, then download everything as a ZIP. Files that fail conversion fall back to their originals inside the same archive — local library work.
