Compress Video to Specific Size in MB
Compress video to specific size by entering any MB limit, checking the bitrate plan, and downloading a verified MP4.
Your source stays in this browser. The requested limit and the smaller encoder target are both shown before processing.
Compress video
The video compressor creates a new MP4 download.
Use percentage for an approximate reduction, or enter MB for a strict maximum file size.
Target-size and platform shortcuts
Choose a target from current platform rules
Before you compress video to specific size for a platform, confirm the limit shown by your own account because rules can change.
Discord
20MBUse compress video to specific size for Discord’s documented 20MB non-Nitro limit, while noting that some users may be in upload-limit experiments.
Gmail
25MBUse compress video to specific size for personal Gmail’s 25MB total attachment limit; Workspace administrators set work and school limits.
Messenger
100MBUse compress video to specific size for Meta’s documented Messenger file sharing up to 100MB in chats.
Open a fixed-size compressor
Use these pages to compress video to specific size with a dedicated safety target, use case, feasibility guide, and retry path.
Compress video with no server upload
Your selected video is processed on your device, not sent to a compression server.
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.
Load online, process locally
Keep a connection available to load the page and video engine. Local processing does not guarantee offline access.
Plan how to compress video to specific size
Use compress video to specific size when an upload form gives you a hard maximum. The tool reads the real source duration and dimensions, reserves audio bitrate, and shows what remains for the picture.
Compress video to specific size with a visible safety target
When you compress video to specific size, the requested limit remains visible while the encoder aims a few percent lower. You can see the exact working target instead of discovering a hidden adjustment after compression.
Requested MB → safe MB
Compress video to specific size from real file data
To compress video to specific size, the page uses the selected video’s actual duration, dimensions, and file size. It calculates total bitrate, audio reserve, video bitrate, expected resolution, and the reduction required.
Real metadata
Compress video to specific size with a hard result check
After you compress video to specific size, the result is compared with the safe target in bytes. A file above the target is marked as missed and is not presented as a successful download.

How to compress video to specific size
The shortest way to compress video to specific size is to set the real upload limit, inspect the calculated budget, and adjust the target or resolution before running a long encode.
Compress video to specific size from a limit or preset
Start compress video to specific size with a custom MB value or choose 5, 8, 10, 20, 25, 50, or 100MB. The input is the external limit; the panel separately shows the safer encoder target.
Compress video to specific size from your source video
Add an MP4, MOV, M4V, WebM, or MKV that the current browser can decode. To compress video to specific size, the tool first reads file size, duration, width, and height without uploading the source.
Compress video to specific size after a feasibility check
Before you compress video to specific size, compare the total bitrate budget, audio reserve, video bitrate, and estimated resolution. A tight or impractical target is explained before encoding begins.
Compress video to specific size, verify, and download
Run compress video to specific size and keep the tab open. The result shows original size, actual output size, reduction, planned bitrate and resolution, then enables download only when the MP4 is under the safe target.
When you can compress video to specific size realistically
Compress video to specific size when clips are long
A 25MB budget lasts much longer for a 20-second clip than for a 20-minute recording. When you compress video to specific size, duration directly determines whether the picture can keep enough bitrate.
Compress video to specific size with a resolution cap
If compress video to specific size predicts a low video bitrate, choose 720p or 480p before retrying. Lower resolution gives each remaining pixel more useful detail than forcing a very low bitrate at 1080p.
Compress video to specific size without an exact-byte promise
Codecs spend different numbers of bits on motion, noise, text, and keyframes. Compress video to specific size therefore aims below the limit, may run a tighter second pass, and always checks the actual result.
Compress video to specific size only when the budget works
When compress video to specific size reports an impractical budget, raise the MB limit, trim the clip, choose 720p or 480p, or use a destination that accepts a larger file or link.
Compress Video to Specific Size FAQ
Continue to compress video to specific size or calculate bitrate
After you compress video to specific size, use the existing 8MB or 10MB tools, open the file-size calculator, or choose a destination-specific compressor with current limit guidance.
Compress Video to 8MB
Compress video to 8MB in your browser. Start with a 8 MB target, compare the output size, and download a smaller MP4.
Compress Video to 10MB
Compress video to 10MB in your browser. Start with a 10 MB target, compare the output size, and download a smaller MP4.
Video File Size Calculator
Use this video file size calculator to estimate MB from duration, video bitrate, and audio bitrate before choosing a compression target.
Compress Video for Gmail
Compress video for Gmail locally with an adjustable 24 MB preset. Download MP4, check total attachment size, or use a Drive link for larger videos.
Browser Video Compressor
Use a video compressor browser to reduce MP4 size locally. Choose a file, set a target MB or percentage, and download a smaller MP4.
Compress Video Without Losing Quality
Compress video without losing quality with a gentler MP4 preset. Keep files local, compare size, and use the largest target that still fits.
