Compress to Target Size
Set a target size and let the tool calculate the bitrate automatically. Local compression keeps your file private while meeting upload limits.
Why target a size?
Meet limits
Aim for upload caps with a clear size target.
Auto bitrate
The tool calculates bitrate for you.
Private output
Compression stays local so files never upload.
How target compression works
- 1
Add a video file.
- 2
Enter the target size in MB.
- 3
Export the compressed video.
Use cases for Compress to Target Size
This page works best when you already know the workflow problem and need a focused browser tool instead of a generic editor.
Shrink delivery files with Compress to Target Size
Use Compress to Target Size when upload limits, email limits, or slow sharing are the real blockers instead of the source format itself.
Create lighter review copies
Generate a smaller preview file before sending it to teammates, clients, or messaging apps that reject the original size.
Reduce friction before distribution
Compression is the right choice when playback already works and you mainly need a file that moves faster through existing workflows.
Before you start
A quick preflight check usually avoids the most common false starts on browser-based exports.
Start from the original local file
Keep the untouched source nearby before running Compress to Target Size, especially if you plan to compare exports or test multiple settings.
Prepare the main video file input
This tool expects a video file file first, so confirm the browser can access the local source you actually want to process.
Settings guide
These are the controls most likely to change the final result or whether the export fits the target workflow cleanly.
Set target size (mb) on purpose
Processing stops once the output reaches this size
Output expectations
These notes help you decide whether this page is the right endpoint or just one step before a later conversion.
Expect MP4 output by default
Compress to Target Size exports a MP4 file, so treat this page as a workflow tool first and a format chooser second.
A new export usually means a fresh encode
Most actions here create a new file, so small quality, timing, or size differences are normal even when the visible change feels simple.
Use Video Converter when format is the real question
If the workflow is correct but the destination type is not, move to Video Converter instead of forcing this page to solve a format-choice problem.
Troubleshooting
Most issues come from the source file, the export target, or a mismatch between the workflow problem and the tool you chose.
The browser rejects the file or export feels stuck
Check that the source really matches the expected video file type and try a shorter or smaller sample first to isolate the issue.
The result is larger or softer than expected
That usually means Compress to Target Size solved the workflow problem but still had to re-encode the media, so compare settings before assuming the source was wrong.
This page solves the wrong problem
If the actual blocker is output format compatibility, email size limits, or subtitle handling, move to the dedicated converter, compressor, or subtitle workflow instead.
