OpenClick 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.
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.
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.
Drag a single slider to brighten dark footage in seconds. Changes preview in real time directly in your browser — no upload queue, no server round-trip for the preview step.
Adjust brightness, contrast, saturation, hue, blur, and opacity in one place. Add an optional cinematic vignette and linear fade in or out for polished exports. Fine-tune every visual layer without leaving the page.
Your file is decoded and re-encoded on your device. We do not store your source video for processing, which keeps your project off our infrastructure and in your control.
Upload MP4, MOV, AVI, MKV, WMV, WebM, and other common types your browser can decode. Export to MP4 (H.264) when available, or WebM (VP9/VP8) for broad compatibility on every OS.
The tool can read most formats your browser can decode, including MP4, MOV, AVI, MKV, WMV, WebM, and many mobile-friendly containers. We recommend H.264 MP4 for the widest predictability. Exports are MP4 (H.264) when your browser can encode it, or WebM otherwise — use our video converter for additional containers after export.
From this page you can export directly to MP4 or WebM. If you need MOV, MKV, AVI, or GIF, download the result and use our free video converter or GIF maker, which are optimized for those workflows.
Yes. The preview player updates in real time as you move the sliders, and a before/after view lets you compare the graded result with the unmodified source. Fade in and fade are calculated during export; the preview still reflects your overall exposure, color, and timing intent.
The heavy lifting happens inside your session using your device’s capabilities. We do not run a required cloud render pass for the core color pipeline, which means fewer copies of your media on external systems. Use HTTPS, keep your browser updated, and only download the finished file to trusted storage.
Brightness moves the whole image lighter or darker. Contrast stretches or compresses the distance between the brightest and darkest parts, adding punch or flattening the image. A practical recipe is to set brightness first, then add contrast, then fine-tune saturation for the mood you want.
The free on-page experience supports up to 500 MB per file in this build. If you need larger or batch work, an account and higher limits may be offered separately — the interface will surface a clear prompt when a file exceeds the cap.
Try a slight reduction in brightness, a moderate increase in contrast, a small reduction in saturation, and a vignette between 30% and 50% intensity. Small hue tweaks can nudge a scene toward teal-orange warmth or cooler daylight depending on the story.
Yes. The interface is responsive, touch-friendly, and the same color controls are available. Very large files or long runtimes will take more time to encode on mobile chips — plug in the device and keep the tab active for best results.
