How it works
Step 1 — Upload Your Video
Click the upload area or drag and drop your file. The free tier allows files up to 500 MB. Supported inputs include MP4, MOV, AVI, MKV, WMV, WebM, and most formats the browser can decode. If you use Google Drive or Dropbox, download the file first (cloud pickers can be added in a future update) — then the tool loads metadata instantly.
Step 2 — Adjust the Settings
Use the sliders in the right-hand panel. Start with exposure using brightness, then add punch with contrast, and fine-tune saturation for natural or vivid looks. The preview player reflects changes immediately. Use the before/after view to compare against the original at any moment. Add vignette, opacity, and fade in/out for creative finishing.
Step 3 — Export & Download
Choose MP4 (recommended for phones and editors) or WebM, pick a quality preset, and export. A progress bar shows encoding status. When complete, download your adjusted file. Typical short clips under a few minutes finish quickly on modern hardware.
