# FastEdit

> Free, browser-based image and animation editor. 12 output formats, 49 platform presets, 100% client-side via WebAssembly. No uploads, no accounts, no installs.

FastEdit is a browser-based editor for images, GIFs, and short-form video. It converts, trims, crops, blurs, and batch-processes files across 12 output formats entirely on the user's device using WebAssembly. No file ever leaves the browser — there is no server-side processing, no upload step, and no account requirement.

The editor includes 49 one-click platform presets covering 23 platforms (Discord, Telegram, WhatsApp, Slack, YouTube, Instagram, Twitch, X/Twitter, and more), automatically configuring format, dimensions, and file size limits. A smart fit-to-size feature auto-reduces quality across up to 3 encoding passes to meet platform file size constraints.
