Really free? Yes โ€” completely

This screen recorder is truly free: no sign-up, no watermark, no limits on recordings or length, and ultra-HD capture up to 4K at your screen's native resolution. All encoding happens locally in your browser โ€” no server costs, so it stays free forever.

How to record crisp text

  • Pick the exact window or tab instead of the entire screen when possible โ€” capture stays at native resolution.
  • "Crisp text" auto-scales bitrate to resolution (1080p โ‰ˆ 8 Mbps, 4K โ‰ˆ 30 Mbps); "Maximum" adds 50% more.
  • Encoding uses H.264 High Profile with a keyframe every 2 seconds โ€” scrubbing stays smooth and text refreshes quickly.

Audio notes

  • "System audio": tick "Share tab audio" (or system audio on Windows) in the browser picker; on macOS only tab audio is capturable in most browsers.
  • "System + mic" mixes both tracks in real time โ€” good for narrated demos.
  • Everything is encoded locally (AAC 128kbps); nothing is uploaded.

FAQ

Is it really free with no watermark? Yes โ€” truly free (no sign-up), unlimited recordings, exports carry no watermark, and capture goes up to 4K ultra-HD. The tool runs entirely in your browser.

Why MP4? MP4 (H.264 + AAC) plays everywhere โ€” chats, players, editors. On browsers without WebCodecs (e.g. Firefox) the tool falls back to WebM and tells you.

Does pausing leave a gap? No โ€” pause/resume is timestamp-compensated, so the exported file skips paused time seamlessly.

Recording length limits? No hard limit, but the file is assembled in memory โ€” for hour-long 4K sessions keep an eye on RAM. GIF export is capped at 600 frames.
