Dead air and a string of "ums" make a good talk sound unsure. Cutting them by hand means scrubbing the whole timeline and slicing one gap at a time. Here is how to remove silences and filler words from a video automatically in your browser — one click finds the pauses and the "ums," you approve what goes, and the gaps close on their own.
What you need
A recording with talking in it — a demo, a lesson, a podcast, a to-camera video. Record one at /record or open an existing one in the editor at /edit. It all runs in the browser, nothing to install. The free plan records up to 5 minutes at 720p, unlimited and forever; Pro is $7.99/mo for longer recordings and higher resolution.
Step 1 — Click the ✨ Polish button
In the editor, click ✨ Polish. It scans the clip and marks two things right on the timeline so you can see exactly what it plans to touch:
- Amber — silent pauses and dead air
- Red — filler words like "um" and "uh"
Step 2 — Remove the silent pauses
The amber marks are the silences Polish detected. Remove them all in one click, and it uses a ripple-close — the clips on both sides of each pause slide together so the timeline stays continuous. No gaps, no freeze frames, no re-aligning anything. A rambly five minutes often tightens to four just from this.
Step 3 — Remove the filler words
The red marks are the "ums" and "uhs." Polish finds them using the recording's Whisper word timing, so it knows where each filler starts and stops down to the word. Clear them and your delivery sounds decided instead of hesitant — the difference between "so, um, the thing is…" and "the thing is…"
Step 4 — Review before you commit
This is the part that matters: nothing is deleted until you click Remove. You see every amber pause and red filler first. Want to keep a deliberate beat before your punchline, or a "hmm" that's actually you thinking on purpose? Leave it. And the whole cleanup is a single undo step — if you cut too aggressively, one press of undo restores the lot, then you can redo it more gently.
Step 5 — Export the tightened video
With the pauses and fillers gone, export as usual — Export → MP4, or send it straight to YouTube from the editor. If you're making short clips too, run Find Clips (AI) after Polish so the AI picks moments from your already-tightened cut.
Tighten your next recording in one click
Polish finds the pauses and the "ums" — you approve, it closes the gaps. Free, in-browser.
Start free →How it compares to Descript
Descript is the name people reach for on this — its "remove filler words" and silence removal are genuinely good. The catch is that Descript is a desktop app you install on a paid plan, and you bring your video into it as a separate step in a separate tool.
EZ Web Streams does the same two jobs — silence detection with ripple-close, and Whisper-timed filler removal — inside the free browser editor you already recorded in. There's nothing to download, and it's the same "see it, approve it, one undo" flow: Polish shows you the amber pauses and red fillers, you decide, and it closes the gaps cleanly. You stay in one tab from recording to a tightened, exported video.
FAQ
How does it find the silences and filler words?
Polish detects silent pauses from the audio and marks them in amber. For fillers like um and uh, it uses the recording's Whisper word timing to pinpoint each one and marks them in red. You see everything it found before anything is removed.
Will it delete parts of my video I wanted to keep?
No. Nothing is deleted until you click Remove. You review the amber pauses and red fillers first, and you can leave any of them in. When you do remove them, it's a single undo step, so one press of undo puts everything back.
Does removing a pause leave a gap in the video?
No. Removing a pause uses a ripple-close, so the clips on either side slide together and the timeline stays continuous. There's no silent gap or freeze left behind.
Do I need to install anything like Descript?
No. Polish runs in the browser inside the EZ Web Streams editor, with nothing to download. Descript does the same kind of silence and filler removal but as a desktop app on a paid plan; here it's part of the free in-browser editor.
