ReduceGIF：在瀏覽器中壓縮、裁剪、反轉 GIF 及移除背景
I built ReduceGIF — compress, crop, reverse & remove GIF backgrounds in your browser
AI 導讀
ReduceGIF 是免費的瀏覽器 GIF 工具，可壓縮、調整大小、裁剪及反轉 GIF，亦可透過色鍵或裝置端 AI 去背移除背景。檔案在瀏覽器本機處理，無需帳戶，亦不會加上浮水印；GIF 壓縮使用以 WebAssembly 編譯的 gifsicle。

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
