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

Convert PNG images to GIF in your browser — each PNG 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.
Convert JPG photos to GIF in your browser — each JPG 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.
Convert WebP images to GIF in your browser — each WebP 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.
Grade videos with 18 filters across Color, Artistic, Blur, and Lighting (grayscale, sepia, pixelate, gaussian blur, vignette, brightness/contrast/saturation) plus a live still-frame preview. Export MP4, WebM, or GIF — local FFmpeg work, 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.
BMP (Bitmap Image File) uses uncompressed encoding and is best for legacy software compatibility, raw pixel data transfers, and simple image processing tasks. GIF (Graphics Interchange Format) uses lossy (limited to 256 colors) encoding and excels at simple animations, memes, and images on platforms that support animated GIFs natively. 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.
Your still image encodes to a single-frame GIF locally via the bundled gif.js worker (2 workers, quality 10, workerScript /gif.worker.js) using the encodeGif path in ImageCatchAllConverter. BMP input decodes natively in the browser before encoding.
No — output is a single still frame, not an animation. Use the video-to-gif tool to cover animation.
Transparency flattens to white — no transparent option is passed to the encoder, so any see-through areas become white in the GIF.
No. Conversion runs entirely in your browser and nothing is uploaded, so downloads on this local tool are unlimited.
GIF to BMP
GIF to BMP output is not produced here — GIF input decodes, but Canvas cannot encode BMP, so conversion fails locally. Convert GIF to PNG/JPG/WebP instead — local, unlimited saves.
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.
Image Format Converter
Convert one browser-decodable image to PNG, JPG, or WebP — the only outputs canvas can encode. HEIC/SVG/JXL/TIFF and other exotic targets fail honestly instead of pretending. Nothing is uploaded; every conversion runs in your browser.
