Online Video Editor

Install & offline

Preparing offline access. Stay connected until it is ready.

After the first online visit finishes caching, you can open the home page and every tool offline, edit local videos and download results. The online music library needs an internet connection; local music works offline. Format support still depends on your browser’s codecs.

The cache contains application resources only. Exports may use separate temporary browser storage. Download results before closing or reloading. If site data or the cache is cleared, reconnect to prepare offline access again.

You can also use Install app or Add to Home Screen in your browser menu. On iPhone / iPad, use Safari’s Share menu → Add to Home Screen. If installation is unavailable, you can still use the site in your browser.

Diagnostics

Check browser capabilities and copy a limited report for troubleshooting.

All help pages

Run checks to prepare a report containing only the app version, capability results, proxy configuration status and local connection indicators. It excludes file names, saved watermark text, video URLs, tokens and browser identity. Copying does not send the report.

These checks use fixed sample configurations (720p video and stereo audio). API availability and codec support do not guarantee that a particular file can be processed. No video is read or uploaded. Temporary storage access and capacity are checked when exporting.

What is in the report

The report contains the application version, connection mode and browser capability checks. It does not include media, filenames, video addresses, watermark text or saved presets. Copying it does not send it anywhere.

Reporting a problem

Describe which tool failed and the steps that led to the error. Review the report before sharing it through the feedback form. Do not include private video addresses or access tokens.

How to use

  1. Select videos

    Select or drop one or more videos.

    The subtitle tool handles one video at a time and imports text, timing and line breaks from SRT, VTT or ASS, without the original styling or effects. Preview in sync, adjust a shared style and position, and shift subtitle timing. Export burns subtitles into the picture and preserves original audio.

  2. Choose a tool

    Choose mute, compression, text watermark, images, stickers, music, cut, crop, canvas or speed for every video. Compression offers quality, resolution and output format controls; the final size is checked after export. Music supports volume, original audio mixing and looping. Text watermarks and images cover the full video by default; drag the time range ends to change when they appear. Each sticker has one visible segment controlled on the timeline. Join combines the list in order; speed changes also change audio pitch.

  3. Process and download

    Start processing and follow each file's progress. Download results individually or as a ZIP. Changing settings requires processing again.

Videos are processed in your browser. Local files are not uploaded. Download results before leaving the editor. Changing language keeps your current files and settings. Large exports are stored as temporary files in this browser. Removing results or leaving the editor deletes them. After an unexpected close, leftover files are cleaned up the next time you open the website. Clearing site data also deletes temporary files. Downloaded files are kept.
