Online Video Editor

Overview

Online Video Editor is a browser-based tool for editing local videos. All processing happens inside your browser: files are never uploaded to any server, and the app requires no registration or login, uses no cookies, and performs no tracking. It supports MP4, MOV, and WebM formats, with a 500 MiB limit per file and a 1 GiB limit for batch processing. It offers a wide range of video editing capabilities: - **Basic Editing**: Cut, crop, join, adjust canvas size and aspect ratio, and change playback speed (audio pitch changes accordingly). - **Audio Processing**: Mute (remove audio) or add background music (with volume control, mixing with the original audio, and looping). - **Overlays**: Add text watermarks, image logo watermarks, and timed stickers. Watermarks cover the entire video by default; drag the timeline endpoints to adjust their duration. Stickers have independent time-range settings. - **Compression & Subtitles**: When compressing, you can adjust quality, resolution, and output format. The subtitle tool lets you import an SRT, VTT, or ASS file, preview it, adjust its style and position, and shift its timing. On export, subtitles are burned into the video while the original audio is preserved. Once cached during your first online visit, the app works offline—the homepage and all tools run without an internet connection, though the online music library still requires one. The cache stores only app assets, not your videos, music, or exported files; closing or refreshing the page clears the current files and results. You can also install it as a PWA via your browser's "Install app" or "Add to Home Screen" option. Ideal for users who need to quickly process videos locally without uploading footage to the cloud. The same developer also offers ClipFlow, an app for iPhone and iPad.
