What's the best way to compress MP4 for LinkedIn?

Upload your .mp4 file, pick LinkedIn as the platform (it's already selected on this page), and compress. We'll target 1000 MB to stay safely under LinkedIn's 5 GB cap. Output is MP4 H.264 that plays inline on LinkedIn.

Does LinkedIn accept MP4 files directly?

LinkedIn plays MP4 inline. Your format is already right — you just need it smaller.

Will quality drop when compressing to fit?

For short clips under a few minutes, the difference is hard to notice on a phone screen. For longer videos, we scale down resolution (1080p → 720p) before degrading quality at the original size. You can also trim the video to the highlight reel before compressing — that preserves full visual quality in the kept portion.

Do I need an account?

Compress MP4 for LinkedIn

Compressing MP4 for LinkedIn comes down to three constraints: LinkedIn's 5 GB cap, its 1920:1080 resolution ceiling, and the need to output MP4 H.264 for reliable inline playback. MP4 source files are typically 1080p at around 100 MB per minute — right at LinkedIn's 1000 MB target. We calculate a per-clip bitrate budget from your duration, subtract 192 kbps for audio, and allocate the remainder to H.264 video at the highest quality that fits. MP4 source retains its H.264 stream without re-containerization work — we simply recompute the bitrate. LinkedIn accepts MP4 inline, so the work here is purely bitrate reduction.

How to compress MP4 for LinkedIn

1Drag your .mp4 file onto the upload zone above (or browse to it).
2LinkedIn is already selected — we'll target 1000 MB to stay safely under the 5 GB cap.
3Optionally trim to a highlight clip or switch to H.265 for 30-50% smaller files at the same quality.
4Download the compressed MP4 and share it on LinkedIn. Source file auto-deletes from our servers after 1 hour.

What to know about MP4 → LinkedIn

MP4 source retains its H.264 stream without re-containerization work — we simply recompute the bitrate.
Resolution is kept at up to 1920p when the bitrate budget allows.
Trim to the highlight before you compress — every 10 seconds you cut gives remaining frames more bitrate to work with.
LinkedIn's 1000 MB target leaves a 5% safety margin below its 5 GB hard cap, so platform-side rejection is never an issue.

The compression math

A 1-minute MP4 at 1080p = ~100 MB. LinkedIn's 1000 MB target minus 192 kbps audio = ~139618 kbps video budget. H.264 at that budget kept at up to 1920p when the bitrate budget allows produces a file at the target size that plays inline on LinkedIn.

About MP4 files

MP4 is the most universally compatible video format in the world, supported by every device, browser, and social media platform. It uses H.264 video encoding and AAC audio, delivering excellent quality at relatively small file sizes. Despite this efficiency, phone-recorded MP4 files are often 100MB or more per minute at 4K, far exceeding platform limits like WhatsApp's 16MB or Discord's 10MB. CompressYourVideo.com reduces MP4 file size by recalculating the optimal bitrate for your target platform, preserving the highest quality that fits within the limit. The output remains MP4 H.264, so compatibility is never an issue. This is the most common compression task: most uploads to our tool are already MP4 files that just need to be smaller.
