Asset Prep for Open Source Projects
Where FastEdit helps
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 project website. One source image, multiple exports, no proprietary tool in the pipeline.
Release Notes and Social Previews
Create Open Graph images, release graphics, and small demo clips for release announcements. Use the presets for GitHub, Open Graph, and social platforms so project updates render correctly everywhere.
Tools that fit Open Source Maintainers & Contributors work
Local-First Processing
Every asset stays on your machine during editing and export. That is useful when you are working on unreleased features, private forks, or sensitive screenshots.
README and Docs Friendly Outputs
Export GIF, WebP, PNG, JPEG, MP4, or WebM depending on where the asset will live. FastEdit covers the common formats used in READMEs, static sites, docs portals, and release posts.
GitHub, Open Graph, and Favicon Presets
Built-in presets handle common project-asset targets like social preview cards, favicons, and profile images so you do not have to look up dimensions every time.
Client-Side Processing
Processing runs in the browser via WebAssembly and browser media APIs. There is no upload step for editing or export, which keeps asset prep fast and private.
15 Input / 12 Export Formats
Handle WebP, GIF, APNG, MP4, WebM, AVIF, PNG, JPEG, JXL, BMP, TIFF, and ICO. Cover the formats you hit in documentation, websites, issue trackers, and release assets without jumping between tools.
Free, No Account, No Watermarks
Open the URL and start working. No signup flow, no watermark on exports, and no paid gate between you and a usable project asset.
