Introducing QuickEditVideo — Free, Private, In-Browser Video Tools (No Uploads)

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
