Video Filters — Grayscale, Brightness, Contrast & More Online Free

AT USE Video Filters applies professional colour and tone corrections to any video in your browser — no video editor, no desktop software, and no account required. Upload an MP4, MOV, AVI, or WebM file up to 100 MB, pick one of eight filter presets, click Apply Filter, and download the processed MP4. Everything runs on our server using FFmpeg — the same open-source video engine used in VLC, HandBrake, and hundreds of professional video platforms.

The eight filter presets

Brightness Boost and Brightness Reduce lift or lower the overall luminance of every frame. Use Brightness Boost to recover underexposed footage from indoor shooting or evening light; use Brightness Reduce to calm overexposed clips from bright outdoor scenes. Contrast Boost increases the separation between the lightest and darkest areas of the frame — useful for flat, hazy footage that looks washed out. Contrast Reduce softens the tonal range, which can help harsh lighting look more cinematic.

Grayscale removes all colour information, converting the video to monochrome. The tonal relationships between light and dark areas are preserved exactly — grayscale does not flatten the image, it reinterprets it in luminance only. Sepia adds the warm brown-orange tone associated with analogue photography and historical footage. Both Grayscale and Sepia are one-click transformations with no configuration required.

Saturation Boost intensifies all colours simultaneously — greens become greener, skies become bluer, and skin tones become warmer. It is the quickest way to add visual punch to flat-looking footage. Saturation Reduce desaturates partially, landing between full colour and grayscale — useful for a muted, editorial aesthetic without going fully monochrome.

Output format

The output is always an H.264 MP4 file, encoded at CRF 23 for a balance of quality and file size. Audio is preserved unchanged. The output filename is the original filename with the filter name appended — for example, clip_grayscale.mp4. Files are deleted from the server immediately after download.
