Image & Animation Tools Built for Developers
Scenarios
README GIF Creation
Record your terminal or UI, drop the screen capture into FastEdit, trim to the relevant segment, crop out window chrome, and export as an optimized GIF or WebP. The timeline editor lets you cut dead frames so your README demos stay tight.
Favicon & App Icon Generation
Export to ICO directly in the browser. Resize your logo to 16x16, 32x32, or 192x192 using the crop and resize tools, then export as ICO, PNG, or SVG, no need to juggle ImageMagick commands or online favicon generators.
OG Image Sizing
Use the built-in platform presets to hit the exact 1200x630 dimensions that Open Graph requires. Crop, adjust, and export as JPEG or WebP with the quality slider tuned to keep file sizes under social platform limits.
Web Asset Optimization
Convert PNGs and JPEGs to WebP or AVIF for your web projects. The side-by-side compare view lets you verify quality at different compression levels before committing assets to your repo.
Screen Recording Trimming for Bug Reports
Trim screen recordings to show only the relevant bug reproduction steps. Cut the beginning and end with the timeline editor, then export as MP4 or GIF to attach directly to GitHub issues.
CI/CD Asset Pipeline Prototyping
Quickly test format conversions and compression settings in the browser before scripting them into your build pipeline. Compare WebP vs AVIF output quality and file sizes side by side to make informed decisions.
Key Features
12 Output Formats
Export to WebP, AVIF, GIF, PNG, JPEG, ICO, MP4, WebM, APNG, MKV, BMP, and TIFF. One tool replaces a chain of CLI converters.
Side-by-Side Compare
Preview output quality against the original before exporting. Dial in the exact quality-to-size ratio you need for web assets.
Timeline Editor with Trim
Cut screen recordings and animations frame by frame. Remove dead time from bug report videos and README demos without launching a video editor.
100% Client-Side via WebAssembly
Nothing leaves your machine. No server uploads, no API keys, no rate limits. Works offline once loaded, useful on locked-down corporate networks.
Smart Fit-to-Size
Set a target file size and FastEdit auto-adjusts quality to hit it. Useful when platforms enforce strict size limits on avatars, favicons, or upload attachments.
Platform Presets
49 presets across 23 platforms handle the exact dimensions and format requirements for Discord, Slack, GitHub, and more, no Googling specs.
