Screen Tools is a free Chrome and Firefox extension that records your screen, a window, a tab or your camera, with microphone and system audio, and takes annotated screenshots. There's no account and no watermark. Nothing leaves your computer unless you connect Google Drive, Dropbox or your own upload server and upload a file.

This wiki covers how to use the extension and how it's built. The README has the short version, and the changelog lists what changed in each release.

Using Screen Tools

• Installation and Updating: install the release zip as an unpacked extension and keep it up to date.
• Firefox: installing in Firefox and how it differs from Chrome.
• Recording: capture modes, audio, the camera overlay, formats, autosave, playback and saving.
• Screenshots: area, visible and full-page captures, and the annotation editor.
• Uploading: uploading to Google Drive, Dropbox or your own server, and share links.
• Settings: every option and its default.
• Troubleshooting and FAQ: known limits and fixes for common problems.
• Privacy: the privacy policy.

How it works

• Screenshot Pipeline: capturing, stitching and annotating screenshots.
• Upload Pipeline: connectors, sign-in and how a file gets to Drive, Dropbox or an upload server.
