Features

Everything you need to record, edit and share

Five tools in one tab. No accounts, no uploads, no watermarks.

How it works

From record to share in three steps

  1. 1

    Record

    Pick a screen, window or tab. Add your webcam, microphone or system audio. A short countdown gives you time to get ready.

  2. 2

    Edit

    Trim the clip, crop it, blur anything private (even when it moves) and add captions. Preview it right away.

  3. 3

    Export

    Choose YouTube, Slack, a small chat file or a GIF. Download it. There is no watermark and no upload.

Private by design

Your recordings never leave your device

Most online recorders send your video to their servers first. Recnook does the work in your browser instead.

FAQ

Questions people ask

Is Recnook really free, with no watermark?

Yes. There is no sign up, no paywall and nothing is added to your videos. What you record or export is exactly what you see in the preview.

Are my recordings uploaded anywhere?

No. Recording, trimming, blurring, converting and exporting all happen inside your browser tab, using your own computer. Your video and image files are never sent to a server. The page does load a small analytics script that counts visits, but it never sees your files.

Does it really work offline?

Yes, after your first visit. The first time you open the site, your browser saves the app on your device. After that it opens and works with the internet turned off. Text extraction from images (OCR) also needs a one time download of its language data, so run it once while online and it will work offline after that.

How do I record my screen with audio in Chrome?

Open the Screen recorder, tick System or Tab Audio for the sound coming from your computer and Microphone for your voice, then press Start recording. In the browser prompt, pick a tab, window or screen and turn on Share audio. Chrome and Edge on Windows can share the whole system sound. On a Mac, browsers usually share the sound of one tab only.

Which browsers and devices does it support?

Screen recording and screen capture need a desktop browser, ideally Chrome or Edge, on Windows, Mac, Linux or a Chromebook. Phones and tablets do not allow web pages to record the screen. The editor, audio trimmer, image converter and combine tools still work on phones.

Can I record Zoom, Google Meet or Teams calls?

Yes, if you share the call window or tab and turn on audio sharing. Tick Microphone as well to include your own voice. Always tell the people on the call that you are recording, and check your company rules first.

Can I pause and resume a recording?

Yes. Press Pause to stop the clock and the video, and Resume to carry on. The paused time is not in the final video, so you get one clean clip without dead air.

What quality and frame rate can I record at?

You can ask for the best available size, 1080p or 720p, and 15, 30 or 60 frames per second. The browser gives you the closest it can, depending on your screen and computer. Use 30 fps for most tutorials and 60 fps for games or smooth animations.

Is there a countdown before recording starts?

Yes. After you choose what to share, a 3 or 5 second countdown gives you time to switch to the right window. You can turn it off if you do not need it.

How do I blur a face or private details in a video?

Open the Trim, mark and blur tool, load your video, pick Blur box and drag over the area. Set when the box should appear and disappear. If the thing you are hiding moves, press Follow motion on that box and the app will move the box along with it.

How does the blur follow a moving object?

The app looks at the pixels inside your box, then finds where that same patch of pixels went in the next frames. It works best on objects that stand out from the background. It is a simple tracker, not magic, so always scrub through the result and fix any spot where the box drifts.

How do I add subtitles or captions to a video?

Turn on Live Speech to Text Captions while recording, or load a .srt or .vtt file in the editor. You can edit every line and its timing, then burn the captions into the exported video or download them as a .srt file.

Can I turn a screen recording into a GIF?

Yes. Load the video in the Trim, mark and blur tool, trim it to the moment you want, choose a GIF width and frame rate, and press Export as GIF. It is made on your own device, and clips up to about 30 seconds work best. Keep GIFs short and small, because they get big quickly.

Can I crop a video to show only part of the screen?

Yes. Choose Crop in the editor, drag over the area you want to keep, and export. The crop applies to the exported video and the GIF. Press Reset crop to go back to the full picture.

Which video formats and export presets can I use?

Exports are WebM by default, and MP4 when your browser supports recording to MP4. Presets set the size and quality for YouTube, Slack and Teams, or a small file for chat apps. Chat apps change their upload limits often, so check the current limit before you send.

How do I trim a video online without uploading it?

Load your clip in the Trim, mark and blur tool, drag the Start and End sliders to keep only the part you want, and export. Everything happens on your own device, so the video never leaves your computer.

Can I take a screenshot, annotate it and copy the text from it?

Yes. The Screenshot tool captures the whole screen or just an area, or lets you paste or upload an image. Add arrows, boxes, circles, text and blur, crop it, and use Extract text to copy any words in the picture. You can save it as PNG, JPG, WEBP or BMP.

Can I combine several videos or images into one?

Yes. Add your clips or pictures in the Combine tool, put them in the order you want with the arrows, and join them into one file.

Is there a time limit or file size limit?

We do not add one. The limit is your device. Very long or 4K recordings need a lot of memory, so for long sessions record at a lower resolution or in parts.

Can I install it like an app?

Yes. In Chrome or Edge use the install icon in the address bar, or the Install app button at the top of this page when it appears. It then opens in its own window and works offline.

Built as a private alternative to cloud recorders

Recnook uses standard browser features such as screen capture and Web Audio, so all processing happens on your computer. Text extraction is powered by the open source Tesseract.js project.

Ready when you are.

Open the studio, press record, and everything stays on your device.
