What makes ToolDeck a good screen recording editor?
A screen recording is mostly waiting, clicking and talking. The useful parts are short. ToolDeck is built around that: one-click trim and silence removal, speed ramps to skip loading, on-device English captions, and text overlays to point at the right button. Export a clean MP4 with no watermark, no account, no upload.
It is best for software tutorials, product demos, onboarding walkthroughs and bug reports up to about 15 minutes in 1080p. It does not record the screen itself — use your OS recorder or OBS — and it does not include cloud stock or cloud AI. The AI captions recognise English speech; other languages can be supplied as SRT/VTT subtitles.
How to edit a screen recording in 3 steps
- 1
Drop a screen recording on the timeline
Video, slide images and audio on one timeline. Trim, split and reorder. Nothing is uploaded — the recording stays on your device.
- 2
Trim, cut silence, add captions and text overlays
Open the AI Captions tab to transcribe on-device. Use Silence Removal for pauses, and add text overlays to highlight UI buttons and steps.
- 3
Export MP4 up to 4K, no watermark
Choose resolution, frame rate and GPU or CPU. The MP4 renders with captions baked in. Export the SRT too for YouTube captions or accessibility documentation.
Editing tools made for screen recordings
Trim and split
Cut the beginning, middle or end of a screen recording. Drag clip edges to trim, press S to split at the playhead, and ripple delete or Close Gaps to remove the empty space. Perfect for removing waiting, loading and accidental recordings.
Silence removal in one click
Narration is full of pauses. Set the noise threshold and minimum pause, and the editor finds every quiet stretch and closes the gap — or apply it to a whole track in one pass to tighten a 20-minute walkthrough.
AI auto captions on-device
Whisper transcribes English speech into editable caption clips without uploading the recording. Captions make tutorials watchable without sound and searchable by YouTube — the model downloads once and runs in your browser.
Zoom and text overlays
Add text titles on the Text track and image overlays on the overlay track to highlight important UI buttons and menus. Zoom into the action by scaling the main clip on a segment — ideal for tutorials and product demos.
Multi-track timeline
Video on the main track, overlays and stickers on the overlay track, titles on the Text track and two audio tracks for voice and music. Trim, split, snap, ripple delete and 100-step undo.
Speed ramps for loading screens
Speed up slow loading, install or setup sections to 4x, slow a key interaction to 0.25x, or freeze a frame while the narration catches up. Detach audio from a clip if the audio needs to stay normal.
MP4 export up to 4K 60fps
WebCodecs encodes H.264 with AAC audio using your GPU when supported, else CPU. Choose resolution, frame rate and engine per export. Output is a clean MP4 with no watermark — ready for YouTube, docs or a knowledge base.
No sign-up, no upload
Screen recordings often contain internal or client data. ToolDeck never uploads the recording — editing and rendering happen in your browser. No account, no email wall, no watermark.

What works well, and where ToolDeck stops short
Everything runs on your computer. Cloud-only features and screen capture are not included. Check this table before a big project.
| Scenario | Result | Notes |
|---|---|---|
| Short tutorials (≤ 15 min) | Works well | Fast 1080p export on a desktop. |
| Long recordings (30+ min) | Split into parts | Browsers limit memory. |
| AI captions in English | Works well | Review names and accents. |
| Other languages | SRT/VTT import | The built-in model is English-only. |
| 4K export | Needs strong PC | 1080p is plenty sharp for tutorials. |
| Record screen | Not included | Use your system screen recorder or OBS. |
Tips for tighter screen recordings
Trim loading screens before captioning
Cut dead air, waiting and loading first — a shorter timeline makes captioning faster and cleaner.
Use 1080p for fast render times
1080p renders quickly and is plenty sharp for a screen recording. 4K doubles memory and render time for little visible gain.
Add text overlays on important UI buttons
Put a text clip on the Text track and time it to the moment the button is clicked. The caption is baked into the export — perfect for help center articles.
Cut silence between pauses in narration
A single click on the Audio tab removes every pause. Apply to all clips to clean the whole walkthrough in one pass.
ToolDeck vs cloud screen recording editors
Cloud editors upload your recording, render on their servers and often record the screen themselves. ToolDeck trades the recorder and cloud extras for privacy and no limits: nothing uploaded, nothing watermarked. Use your own screen recorder, then edit here.
| Feature | ToolDeck | Typical cloud editors |
|---|---|---|
| Your screen recording is uploaded to a server | Never | Usually yes, for cloud rendering |
| Watermark on export | None | Varies by plan |
| Sign-up needed | Not required | Often required |
| Free-plan length cap | None from ToolDeck | Often 5–15 min |
| Trim, split and rearrange clips | Yes | Yes |
| AI auto captions | Yes, English speech (on your device) | yes, sometimes paid |
| SRT / VTT subtitle import/export | Yes | yes, on some plans |
| Silence removal | Yes | Not always available |
| Works offline after loading | Editing yes, AI model needs first download | No |
| Record screen inside the app | No | yes, in some |

Screen recording editor FAQ
Answers on price, privacy, captions, trimming, export and how to record the screen.
Free, watermark and sign-up
Is ToolDeck really a free screen recording editor?
Yes. ToolDeck edits screen recordings free with no credits, no paid tier and no watermark. Every feature — trim, silence removal, on-device captions, text overlays, MP4 export — runs in your browser and needs no account.
Do I need an account?
No. Open the page, drop your recording and start editing. No login, no email wall, no trial.
Is it free forever?
Yes — no credit card, no trial, no upgrade nudge. The practical limits are device memory, CPU/GPU speed and the 1 GB per-file cap.
How does it compare to paid screen recording editors?
Paid editors often charge per export, watermark free plans or tie you to a cloud account. ToolDeck is free, private and no-account. It does not record the screen itself — use your OS screen recorder or OBS, then edit the file here.
Privacy and no upload
Is my screen recording uploaded?
No. Editing, captioning and rendering happen in your browser. The only downloads are the editor code and the open speech model from a public CDN. This is important for NDA or unreleased feature footage.
Is it safe for NDA or client work?
Yes — nothing leaves your device, so unreleased features, customer data and NDA footage stay private. Keep your browser and OS updated and avoid shared computers for sensitive work.
Does it work offline?
After the page loads, editing and rendering run locally. AI captions need a one-time model download first.
Captions and subtitles
How do I add auto captions to a screen recording?
Import the recording, open the AI Captions tab and press Generate Captions. Whisper runs on your device and adds caption clips on the Text track. Click any caption to fix the words or pick a style.
Which languages are supported?
The built-in model recognises English. For other languages, import a translated SRT or VTT file and burn it in.
Can I import or export SRT / VTT?
Yes. Press Import SRT/VTT to load a subtitle file, or Export → SRT or VTT to download one for YouTube or accessibility documentation.
Screen recording editing
Can I trim a screen recording?
Yes. Drag clip edges to trim, press S to split at the playhead, and use Ripple Delete or Close Gaps to remove empty space.
Does it have silence removal?
Yes. Set the noise threshold and minimum pause, then cut silent stretches in one click. Apply to all clips to clean a whole track.
Can I speed up slow loading sections?
Yes. Set clip speed from 0.25x to 4x. Use 4x to skip loading, 0.25x to show a key detail. Detach audio if you want to keep the voice at normal speed.
Can I zoom or highlight part of the screen?
Yes. Add text overlays on the Text track and image overlays on the overlay track. For a zoom, scale the main clip on a segment so the UI area is larger.
Export
What formats can I export?
MP4 (H.264 + AAC) in Chrome and Edge. The fallback recorder exports MP4 or WebM. Captions export as SRT/VTT; audio mix as WAV.
What’s the maximum resolution?
Up to 4K at 60fps if the device has enough memory and processing power. 1080p 30fps is faster and plenty sharp for tutorials and product demos.
Why is rendering slow?
Without hardware acceleration the CPU does all the work. Try 1080p, 30fps, fewer effects, close other tabs and keep the tab focused while rendering.
Recording and use
Can I record my screen in ToolDeck?
No. Record with your OS screen recorder (QuickTime, Windows Game Bar, OBS) or a dedicated tool, then drop the file into ToolDeck for editing.
Does it work with OBS recordings?
Yes. OBS exports MP4, MKV or FLV. MP4 imports directly; MKV works if your browser can play it. Convert FLV to MP4 first if the browser cannot decode it.
Is it good for bug reports and QA videos?
Yes — trim to the reproduction, add text overlays pointing at the bug, caption the narration and export a small MP4. Nothing is uploaded, so NDA and unreleased feature footage stays private.
Use media you have the right to edit
Only edit and publish footage, music and images you own or are licensed to use. Screen recordings of third-party software, customer data or unreleased features need permission before publishing.
