Tips for better screen recordings
- Clean your desktop — close unnecessary tabs and applications before starting
- Use a good microphone — built-in laptop mics work, but an external microphone improves audio quality significantly
- Choose the right capture source — recording a single window instead of the full screen creates a more focused video
- Do a test recording — record 10–15 seconds and check audio levels before the real take
- Speak clearly — narrate as you go rather than adding voiceover later

FAQ
Is online screen recording free?
Yes. NanoPix Screen Recorder is completely free with no time limits, no watermark, and no account required. All features are available without payment.
Can I record audio with my screen?
Yes. Enable the microphone option before starting your recording. Your narration will be captured alongside the screen video.
What format are screen recordings saved in?
Recordings are saved as WebM files. WebM offers good quality at reasonable file sizes and plays in most modern browsers. Convert to MP4 using Transcode if needed.
Is there a recording time limit?
No. NanoPix imposes no time limits. Record for minutes or hours—the only limit is your device's available storage space for the output file.
Can I record a specific application window instead of my full screen?
Yes. When the screen share prompt appears, choose "application window" and select the window you want to record. The recording will be cropped to that window's bounds.
Are my screen recordings private?
Absolutely. The recording is saved directly to your computer. NanoPix does not upload, store, or process your recording on any server.
Does the screen recorder work on Mac and Windows?
Yes. NanoPix works on macOS, Windows, Linux, and ChromeOS. Any operating system that supports Chrome, Edge, or Firefox will work.
Can I record system audio along with my microphone?
Currently, browser screen capture primarily supports microphone audio. System audio capture depends on the browser and operating system. Check your browser's screen sharing options.
