Audio and video tools
These tools record straight from your browser, using the screen, microphone and camera features built into it. The recording stays in the page until you save it, and nothing is uploaded to us or anyone else.

How to choose the right tool
For audio, use the MP3, WAV and video to MP3 converters, the audio cutter and joiner, and the speed changer and volume booster. For video, the trimmer, compressor, speed changer, rotate and format tools, the frame extractor, remove audio, and video to GIF. For capturing, the screen, webcam and voice recorders.
Accuracy, sources and privacy
Audio and video are decoded and re-encoded by your own browser, so files are not uploaded. Video tools play the video and record it as it plays, so they take about as long as the clip; keep the tab open. MP3 is lossy, so each save as MP3 costs a little quality; WAV is lossless but large. Which formats work depends on your browser. Everything on these pages runs in your browser. What you type is not sent to a server, not stored by us and not added to the web address.
Questions about audio and video
Why does video processing take as long as the video?
Your browser plays the video and records the result, so the work happens in real time. Keep the tab open until it finishes.
Which output formats are available?
WebM or MP4, whichever your browser can record. The format list on each tool shows what is available on your device.
Are my recordings uploaded?
No. Recordings and files stay on your device and are saved to your downloads.
What is the difference between MP3 and WAV?
MP3 is smaller and lossy. WAV is uncompressed and larger, about 10.6 MB a minute for CD-quality stereo.
