How to use this preset
- Choose a video from your device.
- Review the 25 MB target and trim if needed.
- Export and check the actual output size.

Compress to 25MB: check size and quality together
A target is a size budget, not a promise of exactly 25MB. Longer videos need fewer bits per second to fit the same budget. Fast movement, fine text, audio and MP4 overhead can change the result.
Recorded export check — September 7, 2026
| Before | Export settings | Observed result |
|---|---|---|
| 8,837,799-byte MP4 36 seconds · 720 × 1280 · no audio | 2.1-second trim · 720p 25MB target | MP4 completed 0.1MB displayed by the editor (rounded) |
The source was already below 25MB and most of its duration was trimmed. This verifies a short export only; it does not prove a compression ratio, visually lossless quality, or that a larger file will fit. A full-length, above-25MB comparison has not yet been published.
Compare the actual exported picture
- Export a short representative section first, including movement and any small text.
- Open the source and downloaded MP4 side by side at the same timestamp and display size.
- Check moving edges for blocks, text for blur and gradients for banding. Listen for audio changes and sync errors.
- If detail is lost, shorten the clip or increase the target. A smaller file is not useful if the content becomes unreadable.
What if the output is larger than the destination limit?
Check the downloaded file’s actual byte size. The editor labels binary units as MB (1 MB = 1,048,576 bytes); a service may instead allow 25,000,000 bytes. For that limit, try a 23MB target to leave headroom, then check again.
Frequently asked questions
Does this video compressor upload my file?
No. Your browser reads and encodes the video locally. Your source video is not sent to YourVideoTool.
Which video formats can I select?
The file picker accepts MP4, MOV, WebM, WMV and other formats your browser or the local FFmpeg compatibility engine can decode.
Can I choose a target file size?
Yes. Enter a target in MB or leave the field empty to use a quality preset. The result can vary because duration, motion, audio and MP4 overhead all affect the final size.
Why might the exported file be larger than my target?
A target is an encoding budget, not an exact guarantee. Leave headroom for a strict destination limit, shorten the clip, or lower the target and export again.
