Four focused tools.
One image at a time.
Reshrimp is a private browser utility for resize, compression, format conversion, and background removal. After the first online visit, the app shell and core tools work offline.
Resize with precision
Scale images to exact pixel dimensions with aspect ratio lock. Perfect for uploads, websites, or sharing. Set width, height, or both — the calculator handles the math.
Convert between formats
Switch between JPEG, PNG, WebP, and AVIF with a single click. Browser-native conversion gives you format-specific tradeoffs, so you can pick WebP for the web, PNG for transparency, AVIF for dense delivery, or JPEG for photos.
Smart compression
Fine-tune quality for JPEG, WebP, and AVIF before processing, then review the updated preview before downloading. PNG stays lossless.
Complete privacy
Every pixel is processed locally in your browser. No servers, no uploads, no tracking, no cookies, no accounts. Your images never leave your device. Verify it yourself — the source code is open.
Runs locally
After the first online visit, the app shell and core tools work offline. Image processing still runs locally in your browser.
Open source
Built with Astro and TypeScript, licensed under MIT. Read the code, fork it, improve it, self-host it. Contributions are welcome — check the GitHub repository for open issues.
Remove background
Browser-based background removal using WebAssembly. Downloads model assets once, then works offline. Exports PNG to preserve transparency.
