TL;DR: I built QuickEditVideo.com — a collection of small, focused video tools that run 100% in your browser via WebAssembly + FFmpeg.
No uploads. No accounts. No watermarks. Free forever.
Why I built this
Most “free” online editors aren’t really free:
- They upload your files to unknown servers
- They watermark exports unless you pay
- They force sign-ups for basic edits
- They’re slow and bloated for quick tasks
I just wanted to trim, compress, or convert a clip without sending a 500MB file anywhere. So I made a browser-first version.
What it does (today)
Each tool is a single focused page:
- ✂️ Trim — frame-accurate cutting
- ➕ Merge — reorder clips and join
- 📐 Crop — remove unwanted regions
- 📏 Resize — fit for platforms/aspect ratios
- ♻️ Convert — MP4, MOV, WebM, GIF, MKV, AVI
- 🎵 Extract Audio — MP4 → MP3/WAV
- 📉 Compress — shrink files for email/DMs
- 🔁 Flip/Speed — mirror, slow-mo, speed-up
👉 Try it: QuickEditVideo.com
Privacy by design
- No uploads: All processing is local in your browser tab
- No account: Open the page → drop a file → done
- No paywalls: No nagging, no surprise limits
- Works offline (once loaded): Great for travel/poor connections
How it works (tech peek)
QuickEditVideo compiles FFmpeg to WebAssembly and runs it client-side. Modern browsers + WASM SIMD make it surprisingly fast.
For devs: the UI translates simple actions to FFmpeg filters/flags.
# Examples of the underlying ops (conceptual)
# Trim 0:30 to 1:10
ffmpeg -ss 00:00:30 -to 00:01:10 -i in.mp4 -c copy out.mp4
# Compress for messaging
ffmpeg -i in.mp4 -vcodec libx264 -crf 28 -preset veryfast -acodec aac -b:a 128k out.mp4
# Convert MOV → MP4 (keep quality)
ffmpeg -i in.mov -c:v libx264 -c:a aac -movflags +faststart out.mp4
