I built ReduceGIF — compress, crop, reverse & remove GIF backgrounds in your browser
Why another GIF tool?
Most online GIF compressors upload your file to a server. That works, but it’s slow, privacy‑awkward, and often watermarked.
I wanted a toolkit that keeps the file on your device and still does the useful edits people need every day.
Meet ReduceGIF
ReduceGIF is a free browser‑based GIF toolkit:
- Compress animated GIFs (gifsicle compiled to WebAssembly)
- Resize by scale or max width
- Crop with a drag selection
- Reverse frame order
- Remove backgrounds (color key or on‑device AI cutout)
No account. No watermark. Processing happens locally in the browser.
How it works (high level)
- Static site built with Astro
- GIF optimization via gifsicle‑wasm
- Frame decode/encode with gifuct‑js / gifenc
- Optional AI background removal with @imgly/background‑removal + ONNX Runtime Web
- Hosted on Cloudflare Pages
