Frequently Asked Questions
Why convert ICO to GIF?
ICO (Windows Icon) uses lossless (multiple sizes) encoding and is best for favicons and app icons — standard format for website bookmarks and Windows application icons. 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.
How is my ICO encoded as a GIF?
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.
Does ICO to GIF make animated GIFs?
No — output is a single still frame, not an animation. Use the video-to-gif tool to cover animation.
What happens to ICO transparency?
Transparency flattens to white — no transparent option is passed to the encoder, so see-through icon areas become white in the GIF.
Do my ICO files upload anywhere?
No. Conversion runs entirely in your browser and nothing is uploaded, so downloads on this local tool are unlimited.

GIF to ICO
GIF to ICO output is not produced here — GIF input decodes, but Canvas cannot encode ICO, so conversion fails locally. Convert GIF to PNG/JPG/WebP instead — local, unlimited saves.
Bulk Image Format Converter
Convert image batches to JPG, PNG, WebP, AVIF, GIF, BMP, ICO, or SVG 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; applies to lossy encodes). 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.
