Lower the resolution
Choose 1080p, 720p or 480p when the destination does not need the original dimensions.
TARGET-SIZE VIDEO COMPRESSION
Need a video under 25 MB? Start with a 25 MB target.
Choose the video, enter 25 MB, and review the estimated output range before compression starts. The final result depends on duration, motion, audio, resolution and codec support.
Keep the original videoProcess a selected local file and create a separate result.
QUICK ANSWER
Start with the limit, then review the estimate
Set 25 MB as the target and check the estimated output range. If the estimate is too high, lower the resolution, mute unnecessary audio or shorten the clip before compressing.
HOW TO DO IT
Follow these steps.
- 01
Choose the video
Select a local video from the computer. The original file is not changed.
- 02
Set the target to 25 MB
Enter 25 MB as the target. Keep the original resolution or choose 1080p, 720p or 480p. Keep audio or mute it.
- 03
Check the estimate
The extension shows an estimated output range before compression. If 25 MB is unrealistic with the current settings, adjust the resolution or audio first.
- 04
Compress the video
Keep Chrome open while the active job runs. The extension creates a new local output and can make at most one corrective retry.
- 05
Compare and save
Review the actual before-and-after size, preview the output, then download it or open the saved folder.
THE EXPLANATION
Why 25 MB cannot be guaranteed for every video
Final file size comes from bitrate over time. A long, detailed or high-motion video needs more data than a short, simple clip at the same perceived quality.
Audio also uses part of the available size. A strict 25 MB target leaves less room for the video track when the clip is long or the audio bitrate is high.
The extension uses 25 MB as a goal, shows an estimated range, and can make at most one corrective retry. It reports the real result instead of claiming that every file will land on an exact number.
PRACTICAL GUIDANCE
If the result may exceed 25 MB
Mute unnecessary audio
Remove the audio track when sound is not needed.
Shorten the clip
A shorter duration gives the encoder more data per second within the same file-size limit.
Choose a smaller-quality preset
Accept more visual compression when fitting the limit matters more than preserving detail.
Split a long video
Create separate files when one small output would make the entire video unusable.
Use a share link
If the attachment limit is too low for acceptable quality, upload the video to an appropriate storage service and send a link instead.
LIMITATIONS
Limitations
- A 25 MB target is a goal, not a guarantee.
- Final size depends on duration, motion, detail, audio, resolution and the encoder available in Chrome.
- Very long, high-resolution or unsupported videos may exceed safe browser resource limits.
- Chrome must remain open while an active job is processing.
- The original video is not deleted or replaced.
COMMON QUESTIONS
Frequently asked questions.
Will the result be exactly 25 MB?
Not necessarily. The target is a goal. The extension shows an estimate, can make at most one corrective retry and reports the real result.
Should I choose slightly below 25 MB?
If the receiving service enforces a strict limit, a slightly lower target can provide room for container and encoder variation.
Does lowering resolution always help?
It usually reduces the amount of visual detail that must be encoded, but final size also depends on duration, motion, audio and encoder behavior.
Can I compress several videos?
Yes. The current Chrome extension supports a free sequential batch of up to 10 local videos.
Is the original deleted?
No. The extension creates a new output copy.
Is the video uploaded?
No. The selected video is processed on the device. Optional diagnostics may use the internet where enabled, but video bytes, frames and thumbnails are not uploaded for compression.
