Open Source Image Editing, Fully Transparent
Scenarios
README GIF and Demo Creation
Create polished demo GIFs and animated screenshots for your project READMEs. Trim screen recordings to show only the key workflow, crop out window chrome, and export as optimized GIF or WebP that renders directly on GitHub.
Project Asset Optimization
Compress logos, icons, and documentation images for your repository. Convert PNGs to WebP for your project website, or optimize GIFs to reduce repo size without losing visual quality.
Documentation Screenshots
Crop and annotate screenshots for your project docs. Export at consistent dimensions so your documentation pages look uniform. Convert to the format your static site generator handles best.
Favicon and Icon Generation
Generate favicons in ICO format and app icons in PNG at standard sizes for your open source project website. One source image, multiple exports, no proprietary tool in the pipeline.
Contributing to FastEdit Itself
FastEdit is built with TypeScript, WebAssembly, and modern web technologies. The codebase is structured for contributions: file issues, submit PRs, or fork it for your own use case.
Key Features
Fully Open Source
The complete source code is available on GitHub. Audit the processing pipeline, verify privacy claims, understand exactly what happens to your files. No obfuscation, no proprietary modules.
No Proprietary Dependencies
Built with open web technologies: TypeScript, WebAssembly, and standard browser APIs. No vendor lock-in, no license keys, no closed-source libraries in the processing chain.
Self-Hostable
Deploy FastEdit on your own server or internal network. The static build can be served from any web server, a Docker container, or even a GitHub Pages site.
Client-Side Processing
All processing runs in the browser via WebAssembly. No server-side component required. This means self-hosting is as simple as serving static files: no backend, no database, no server resources for processing.
12 Format Support
Handle WebP, GIF, APNG, MP4, WebM, MKV, AVIF, PNG, JPEG, BMP, TIFF, and ICO. Cover every format you encounter in open source project workflows without reaching for proprietary converters.
Free as in Freedom
No cost, no restrictions on use, no premium tier. Use it for personal projects, organizational projects, or commercial work. The open source license ensures it stays free.
