Reduce Dimensions
High ImpactHalving the width can reduce file size by 60-75%. Most GIFs look fine at 400-480px for web use.
Lower Frame Rate (FPS)
High ImpactReducing from 30 to 15 FPS roughly halves the number of frames and file size. 12-15 FPS is smooth enough for most uses.
Reduce Color Count
Medium ImpactGIFs support up to 256 colors per frame. Reducing to 128 or 64 colors can cut file size with minimal visible difference.
Trim Duration
High ImpactEvery second of animation adds frames. Cutting a 10-second GIF to 5 seconds roughly halves the file size.
Apply Lossy Compression
Medium ImpactLossy compression slightly reduces quality but can achieve 20-40% additional size reduction on top of other optimizations.

Why Client-Side GIF Compression Matters
Most online GIF compressors require you to upload your file to their servers. This means your GIFs — which might contain personal content, screen recordings, or sensitive information — travel across the internet and sit on someone else's server.
GifConvert takes a fundamentally different approach. All compression runs directly in your browser using WebAssembly technology. Your GIF files never leave your device. There's no upload, no server processing, and no data retention. It's compression with guaranteed privacy.
