No. Processing and previews stay in your browser. Helphonic serves this page and its scripts and checks access settings using non-content usage metadata. Your media, file names and recording contents are not sent to the server or analytics.

Is this tool free?

This tool launches with unlimited free usage for guests, registered users and active paid users. Administrators can change access allowances later. Current access information appears on the tool page; device safety limits still apply.

Will it work on every device?

Screen recording requires HTTPS and a supported desktop browser. Many mobile browsers do not support screen capture. Available audio sources and output formats vary.

How to use

Screen Recorder

Learn how to use Screen Recorder: step-by-step instructions, settings, export options, privacy, limits and troubleshooting.

Step-by-step instructions

  1. Open this HTTPS page in a desktop browser that supports screen recording.
  2. Optionally enable shared tab/system audio, then click Start recording.
  3. Choose a screen, window or tab in the browser’s permission dialog.
  4. Click Stop recording or use your browser’s Stop sharing control.
  5. Preview your recording, click Prepare recording download, and save the file.
Permissions and privacy

You choose what is shared in the browser’s own permission dialog. Permission is required for every recording. Only record material you have permission to share, and close sensitive windows and notifications first.

The tool does not request microphone or camera access. Optional audio captures only audio the browser supplies with the selected screen, window or tab; availability depends on browser and operating system. Recordings are kept in page memory and are not uploaded.

Browser support and download format

Screen capture requires HTTPS and a compatible desktop browser. Many mobile browsers do not provide this API. If unavailable, the page explains that recording cannot start.

The browser selects a supported WebM or MP4 encoder. The requested capture size is 1280 × 720, with a maximum of 1920 × 1080 and 30 frames per second when constraints are supported. No format conversion is performed. Test the downloaded recording in your intended player.

Recording and cleanup

Recordings stop automatically after three minutes. A recording that exceeds 48 MB is discarded to prevent unbounded memory use; make a shorter recording if this happens. Shared-audio and video encoding can use substantial CPU and memory.

Stopping, leaving the page or a recording failure stops active capture tracks. The browser’s own Stop sharing control also stops recording. Download before leaving. Discard recording clears the current preview; this cannot recover an unsaved recording.

Processing and privacy

Files and entered content are processed on your device in this browser tab. File contents and results are not uploaded to Helphonic or sent to analytics. The page still contacts Helphonic to load its tools, check access and confirm non-content usage information. Work is not saved to your account; download or copy results before leaving or reloading the page.

If an operation cannot finish

Use a current browser and smaller inputs if the tab runs out of memory. Some tools download a local processing library or model on first use, so an internet connection is needed even though your content stays on the device.

If the tool reports that access or limits changed, review the current policy and run it again. If usage confirmation is uncertain after an interrupted connection, a retry can count as another operation. Download completed work before reloading; this site does not keep a recovery copy.

About this tool

Start recording and explicitly choose what to share in your browser’s permission dialog. Stop with the tool or browser sharing controls, review the recording and prepare the download. Shared tab or system audio is optional when available. No microphone or camera is requested.
