Choose a tool for the result you need
Start with the part of your recording you want to change. Each tool has its own preview, settings and downloads.
Make a recording easier to hear
Reduce background noise in speech recordings or a video’s audio track. To hide particular words, choose audio censoring and mark the intervals to bleep.
Prepare a video to share
Trim a continuous clip, crop the picture or compress the file in Video Tools. To remove burned-in text or watermarks, use Video Eraser. To hide faces, use face anonymisation and review the coverage before exporting.
Turn speech into text or another language
Transcribe for editable text, translate subtitles to keep the original voice, or dub to create a spoken translation. Review names, numbers and timing before saving.
Where is your file processed?
On your device
Video erasing, compression, trimming, cropping and recovery, noise removal, voice changing, audio bleeping and face covering run in your browser without uploading your file.
With server assistance
Cloud transcription, subtitle translation and dubbing send the audio or text needed for the task to processing services. Each tool explains what is sent before you start.
Before you choose an audio or video tool
Do I need to install editing software?
You can open a tool and select a file directly in your browser. Media support depends on your browser and device. For longer recordings, keep the tab open and allow enough storage for the output.
Which file formats and downloads are supported?
Tools accept common audio and video files such as MP3, WAV, M4A, MP4 and MOV, with support varying by tool and codec. Outputs include processed audio, MP4 video, editable text and subtitle files. Check the tool page for the formats available for your task.
What is the difference between transcription, subtitles and dubbing?
Transcription turns speech into editable text. Translated subtitles add text in another language while keeping the original voice. Dubbing creates a new spoken track using a synthetic voice. Choose based on whether you need text, on-screen translation or translated audio.
Can these tools restore any damaged recording?
No. Noise removal can reduce background noise but cannot guarantee recovery of missing or distorted speech. Video recovery can keep decodable sections when the index is readable; it cannot recreate missing footage. Listen to or watch the result before using it.
