Video resizer & cropper

How this tool works

Enter even whole-pixel output dimensions. Fit inside preserves the whole picture and adds black bars if needed. Center crop fills the output while preserving proportions, which can remove subjects near the edges. Rotation is clockwise and happens before fitting. Check the exported video before using it.

Example: a 160 × 90 landscape video rotated 90° and fitted into 80 × 80 has a portrait image with side bars. Re-encoding is lossy; resizing cannot recover missing detail. MP4 audio timing is measured during export and stops if the correction is unreliable.

One video track and at most one supported mono/stereo audio track up to 96 kHz. Additional known tracks stop video export. Subtitles, chapters, attachments and file-level descriptive tags are not retained; track labels/language may remain. This is not a complete metadata eraser. HDR and transparent-video export are outside scope. An extension alone does not prove codec support.

Up to 4,096 pixels per side and 8,294,400 pixels per frame. Video output is capped at 32 MiB and 18,000 decoded frames; inspection times out after 30 seconds and processing after ten minutes. These limits do not guarantee every device has enough memory. Stop processing keeps your selected file available; Clear file releases its working references. Your original is unchanged.

MP4 uses H.264/AAC and WebM uses VP8/Opus, with a target 4 Mbps video / 128 kbps audio. No remote playlists, DRM bypass, transcription or professional color-fidelity guarantee. Samples are original synthetic Toolfred files and never autoplay. Real-device/browser coverage is still in progress; a local result is not universal compatibility.
