Image & Animation Tools Built for Developers

Q: Can I use FastEdit without installing anything?

Yes. FastEdit runs in your browser with no app install, extension, or account. Open fastedit.net, drop in a file, and export. Processing stays local once the editor and needed encoder path have loaded.

Q: How does FastEdit compare to using ImageMagick or FFmpeg?

FastEdit covers the common image and animation tasks that developers reach for CLI tools to handle: format conversion, resizing, trimming, and compression. The visual interface makes it faster for one-off tasks where writing a CLI command would be overkill.

Q: Does FastEdit upload my files to a server?

No. File processing happens locally in your browser using WebAssembly and browser media APIs. Your files never leave your machine for editing or export.

Q: Can I generate favicons with FastEdit?

Yes. Import your logo or icon, resize it to standard favicon dimensions using the crop tool, and export directly to ICO format. You can also export as PNG for apple-touch-icon and other sizes.

Q: What animated formats does FastEdit support?

FastEdit handles GIF, animated WebP, APNG, MP4, and WebM for both input and output. You can convert between any of these formats and use the timeline editor to trim, reverse, or adjust speed.

You already have enough CLI tools to manage. FastEdit handles the image tasks that pull you out of flow: converting screenshots for docs, sizing OG images, generating favicons, without installing anything or learning yet another CLI. Drop a file in your browser, get the output you need, stay in your workflow.

Where FastEdit helps

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 or PNG, no need to juggle ImageMagick commands or online favicon generators.

OG Image Sizing

Use the built-in Open Graph preset for the recommended 1200x630 size. Crop, adjust, and export as JPEG or WebP with quality controls tuned for social previews.

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.

Tools that fit Software Developers & Engineers work

12 Output Formats

Export to WebP, AVIF, GIF, PNG, JPEG, JXL, ICO, MP4, WebM, APNG, 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.

Local Browser Processing

Nothing leaves your machine. Processing runs locally with WebAssembly and browser media APIs, so there are no server uploads, API keys, or rate limits.

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

79 presets across 23 platforms handle the exact dimensions and format requirements for Discord, Slack, GitHub, and more, no Googling specs.
