Video Resizer for Smaller Upload-Ready MP4 Files
Use this video resizer when you need a smaller upload-ready MP4 and file size matters more than custom crop or aspect-ratio editing.
This page can lower file size and output resolution during compression; it is not a full custom width, height, crop, or social aspect-ratio editor.
Compress video
The video compressor creates a new MP4 download.
Pick the approximate maximum size you want. Compress by percentage or MB; the two fields stay linked.
Compress video with no server upload
The compressor reads the selected MP4 on your device, so private videos do not leave your browser.
Compress by percentage or target MB
Choose roughly how small the MP4 should be. The compressor accepts smaller results instead of chasing an exact file size.
Compress after caching
Open the site once, then the app shell and video engine can be reused when your connection is gone.
Video resizer output and capability boundary
A truthful video resizer page should make the current tool useful without pretending it has custom crop or platform canvas controls.
Target-size resize workflow
The video resizer starts with a smaller target, then compresses the selected video into a more upload-friendly MP4.
45% preset
Automatic resolution reduction
For tight targets, the video resizer can reduce bitrate and output resolution to keep the result practical.
Resolution-aware
No crop or aspect editor yet
Use this video resizer for file-size and resolution reduction, not for custom 9:16, 1:1, crop, fill, or exact width and height control.

How to use this video resizer
This video resizer follows a simple path: choose a video, pick a smaller target, compress locally, then download and preview the MP4.
Choose the video you need to shrink
Open the video resizer, select the MP4, MOV, WebM, MKV, or M4V file, and check its starting size before compression.
Set a smaller target
Use the video resizer target controls to choose a percentage or MB value. Smaller targets may trigger stronger bitrate and resolution reduction.
Compress and preview the result
Run the video resizer, download the smaller MP4, and preview it before uploading or sending it.
Use a dedicated editor for crop and aspect ratio
If you need exact width, height, 9:16, 1:1, fill, crop, or padding, use a full video editor after or before this video resizer workflow.
What this video resizer can and cannot do
Good for smaller MP4 exports
Use this video resizer when the practical goal is a smaller MP4 for email, chat, forms, storage, or a platform upload.
Not a full canvas editor
This video resizer does not expose custom dimensions, crop handles, background blur, or social-media aspect presets yet.
Quality depends on the target
A video resizer that lowers file size must trade off detail. Raise the target MB when text, faces, or screen recordings need more clarity.
