What Resize Video does
Scale a short video to a preset maximum width while keeping its aspect ratio. The tool keeps the operation focused and creates a separate result so the original remains available for comparison.
Resize Video uses a bounded server request with explicit input, time, output, and rate limits.
How to use Resize Video
Before running Resize Video, check the source format and intended destination. Apply one meaningful change at a time so an unexpected result is easier to identify.
- Select a short representative video, animation, or capture source and confirm the displayed duration and dimensions.
- Choose the required timeline range, frame, layout, audio, or output settings for the destination.
- Create the result and watch the complete preview, including transitions and the first-to-last loop boundary when relevant.
- Test the downloaded file in the target browser, player, editor, or publishing service before deleting the source.
Where Resize Video fits
Use this media workflow to prepare a short clip, recording, or animation for a known player, platform, presentation, or editing step. Decide the required dimensions, duration, frame behavior, audio state, and output format before processing so every setting has a clear purpose.
What to check
Pick the smallest preset width that remains clear at the destination, then verify aspect ratio, small text, and playback smoothness in the MP4 output.
Review the whole timeline for correct framing, orientation, timing, animation loops, audio sync, captions, and legible overlays. A short representative clip is useful when choosing compression settings.
Privacy and limitations
Recordings created with browser capture APIs remain local. FFmpeg conversions upload only the selected input file or files and use temporary workspaces with best-effort cleanup after the request.
Browser capture support and playable codecs vary by device. Re-encoding may change quality, exact frame timing, metadata, transparency, or file size, and long or high-resolution media can exceed the documented request or memory limits.
