Compress any video to an exact size.
Set the size you need in megabytes. Portable Video Compressor drives FFmpeg to land inside your leniency band at the best quality it can manage, for one file or a whole batch.
How it works
Three steps to a smaller file
No accounts, no upload, no waiting in a queue on someone else's server. Everything runs on your machine.
Add your videos
Drag files straight onto the window, or click Select Input Video(s). Several at once build a queue that is processed one after another.
Set a target size
Type the size you want in megabytes, for example 10. Leave Auto mode on and the app budgets resolution, frame rate and audio to reach it. The leniency slider sets how close to the target you want to land.
Start compression
Watch the progress bar and per-file status. At the end you get a clear summary of what succeeded, what was skipped, and what failed, with outputs named for you.
What it does well
A precise tool, not a guess
Portable Video Compressor was built to hit a number. Every control exists to help you reach the size you asked for without throwing away quality you did not need to lose.
Aim for an exact size
Hit an exact size in MB, within a leniency band you set.

The run dashboard
See every file at a glance
The Batch Queue lists each video in order and becomes your live dashboard during a run. Rows tint by result, and each row remembers the exact target it ran with, so changing a setting afterwards never repaints history.
- Reorder, remove, or add files by dragging
- Per-file overrides for target, encoder, format and size
- Frozen outcome colors and target figures
