FastEdit is the last-mile editor for media that shows up right before you post, ship, send, or publish. A free, browser-based toolkit powered by WebAssembly — convert, compress, trim, crop, caption, redact, and resize without ever hitting "upload." Your files never leave your device.
Your Files
Never Leave Your Side.
Zero Uploads
The editor loads code, then the actual work happens in your browser. Your files are not sent to a server, not for a second and not "anonymously."
Open your Network tab and watch it stay quiet.
No Account Needed
There is no signup wall before the export button. Open the link, make the change, and leave without handing over an email address.
Just the page, the file, and the job.
Powered by Your CPU
WebAssembly runs the media encoders on your own hardware. Big exports depend on your machine, not on a shared upload queue or a remote worker.
Watch your CPU work, not your Wi-Fi.
I built FastEdit because simple media tasks kept turning into tab hunts: one site for conversion, another for compression, another for captions, all asking for the file. The goal is small: open the page, fix the file, move on.
Drop. Edit.
Export.
Drop Your File
One file for a careful edit, or a folder when everything needs the same cleanup. FastEdit reads the media type and brings the relevant tools forward.
Tweak It
Trim the dead air, crop for the feed, blur a password, add a label, or pick the preset that matches where the file needs to land.
Grab & Go
Export locally and get back to the real task. Since nothing was uploaded, there is no server copy to delete and no queue to wait through.

...Ship Assets Daily
Screenshots to WebP. Favicons in a blink. README GIFs from screen recordings. The small asset prep that should not become a build step.

Media Editing &
Export Features
Timeline Editing
Trim, cut, and splice with frame-accurate control. Turn a wandering 30-second recording into the 3 seconds someone needs to see.
Blur & Redact
Draw blur regions scoped to time ranges. Share screen recordings without leaking passwords, faces, emails, or customer data.
Text & Image Overlays
Add captions, labels, logos, or transparent PNG badges. Drag them onto the preview and time them to the moment they should appear.
Timed Visual Filters
Apply cinematic, noir, high-contrast, duotone, comic, warm, cool, and custom looks to full clips or specific timeline regions.
Batch Processing
Drop a folder. Convert, resize, and re-encode a pile of files in one pass with shared settings — or fix one odd file by itself.
79 Platform Presets
One-click export for Discord, Telegram, Twitch, YouTube, Instagram, X, and 17 more. The fussy format, dimensions, and size limits are already filled in.
Smart Fit-to-Size
Set a target file size and let the encoder dial in quality automatically. No more exporting the same file five times for a platform limit.
Side-by-Side Compare
Synchronized split-view between original and output. See what compression costs before you keep the smaller file.
Background Removal
AI-powered background removal runs on-device after a one-time model download. No uploads, no credits. Works on stills and frame-based media.
Variable Speed
Slow to 0.25× for the key moment, speed to 4× through the boring parts. Multiple speed regions per timeline.
Crop & Resize
Crop, rotate, and resize with aspect ratio locking. Prep avatars, thumbnails, banners, and awkwardly specific upload slots without leaving the editor.
Reverse & Ping-Pong
Play clips backwards or bounce seamlessly between start and end. Perfect for reaction GIFs, seamless loops, and social clips that never stop.

Shrink PNG, JPEG, WebP, AVIF, GIF, or MP4 when the upload field rejects the file at the worst possible moment.
Convert
PDF to PNG. HEIC to JPG. GIF to WebP. MP4 to GIF. Keep the media; change the wrapper that is getting in the way.
