LinkedIn's video specifications shape the technical decisions for compression. The platform officially supports MP4 and MOV containers, with H.264 video and AAC audio as the recommended codec pair. Resolution can range from 256 by 144 up to 4096 by 2304, but the practical sweet spot is 1080p for landscape and 1080 by 1350 or 1080 by 1920 for portrait orientations. Frame rate caps at 30fps, frame rates above that are downsampled by LinkedIn during ingest. Duration runs from 3 seconds minimum to 10 minutes maximum for organic feed posts, with longer 30-minute limits available for LinkedIn Live and 4-hour limits for LinkedIn Learning. File size limit is 5GB, though files much smaller than this still upload and process noticeably faster.
Aspect ratio choice deserves serious thought because LinkedIn's feed is increasingly mobile-first. Landscape 16:9 video remains correct for content shared from desktop to desktop viewers and for talks, interviews, and screen recordings where the original framing was horizontal. Square 1:1 takes up more vertical screen on a mobile feed and is the right choice for short-form explainers, talking-head clips, and announcement videos where catching the scrolling thumb matters. Vertical 9:16 fills the entire mobile screen for a TikTok or Reels style presentation and works particularly well for personal brand content and quick tips. The compression target adjusts with aspect ratio, vertical 1080 by 1920 actually has slightly more pixels than landscape 1920 by 1080, so bitrate should rise accordingly.
Bitrate targets for LinkedIn balance quality against upload speed. For landscape 1080p, 5 to 8 Mbps produces visually clean video with strong text legibility, lower bitrates work for talking-head content where motion is limited. For square 1080p, 4 to 6 Mbps is the corresponding range, smaller frame area lets you trim bitrate. For vertical 1080 by 1920, 6 to 9 Mbps is appropriate because the frame is essentially the same total pixel count as landscape 1080p. Two-pass encoding gains roughly 10 to 15% efficiency at constrained bitrates and is worth the extra encoding time for important posts. LinkedIn re-encodes every uploaded video, so do not push bitrate excessively high, the platform compresses your file further regardless.
Distinguishing organic posts from LinkedIn video ads matters for compression strategy. Organic posts use the standard upload pipeline and respect the 5GB and 10-minute limits. LinkedIn Ads have different requirements and additional checks. Single Image and Video Ads through Campaign Manager support files up to 200MB and 30 minutes, with the same H.264 MP4 codec requirements but stricter caption and accessibility metadata expectations. For ad creative, hold quality higher and consider exporting two versions, a feed-optimised file at 5 Mbps and a backup at 8 Mbps in case the ad gets pulled into a higher-quality placement. Always verify the final ad creative plays cleanly in LinkedIn Campaign Manager's preview before submitting the campaign.
Upload your video and select the LinkedIn preset. Outputs H.264 MP4 at LinkedIn-recommended resolution and frame rate.
Step-by-step guide to compress video for linkedin:
Upload Your Video
Click the upload button or drag and drop your video into the browser. The tool supports MP4, MOV, AVI, MKV, WebM, and most consumer and prosumer formats, including iPhone HEVC, Android H.264, GoPro MP4, OBS recordings, and exports from Premiere Pro, Final Cut Pro, DaVinci Resolve, and Camtasia. Source files up to 4GB process reliably in browser. For larger raw masters, downscale or trim with a desktop tool first, then bring the smaller intermediate into the LinkedIn workflow.
Select the LinkedIn Preset
Choose the LinkedIn preset which sets H.264 video at up to 1080p, 30fps, with AAC stereo audio at 128kbps, the exact specifications LinkedIn recommends in its publisher documentation. The preset targets a moderate bitrate of 5 Mbps for landscape and 4 Mbps for vertical or square, which produces clean professional quality while keeping files well under the 5GB limit. If your content is destined primarily for mobile feed viewing, switch to the square 1:1 or vertical 9:16 variant which takes up more screen real estate and stops the thumb scroll.
Download and Post to LinkedIn
Click Compress and download the resulting MP4 file. Open LinkedIn, start a new post, click the video icon, and select the compressed file. Upload finishes faster than for raw exports because the bitrate is tuned to LinkedIn's sweet spot. LinkedIn's server-side processing also completes faster on a clean H.264 stream than on a high-bitrate MOV or ProRes master. Add captions in the LinkedIn composer since most feed views are silent, write a strong hook in the first two lines of post text, and publish.
Common situations where this approach makes a real difference:
Sharing a company announcement video
A marketing team produces a two-minute announcement of a new product release as a 1080p H.264 master at 800MB. Compressing to LinkedIn-optimised settings brings the file down to 80MB while keeping every graphic crisp and every word of dialogue clear. Upload finishes in under a minute on standard office broadband, the platform-side processing completes within five minutes, and the post goes live during the team's planned launch window rather than slipping into the afternoon.
Uploading a conference talk to LinkedIn
A speaker recorded a 45-minute conference session at 12GB in 4K. LinkedIn caps feed videos at 10 minutes so the talk needs to be trimmed into a highlight reel anyway. Cutting to the strongest 9-minute segment and compressing to 720p at 2 Mbps produces an 800MB file that uploads cleanly. For the full talk, posting a teaser on the feed and linking to the full version on the speaker's LinkedIn newsletter or YouTube channel works around the duration limit while still building reach.
Use when your video needs to be prepared for a LinkedIn post or LinkedIn profile background video.
Get better results with these expert suggestions:
Match resolution to the viewing context for compress video for linkedin
LinkedIn's feed is heavily mobile, with the majority of professional users now scrolling on phones during commutes and between meetings. 1080p is the practical ceiling because viewers on phone screens cannot distinguish higher resolution and the platform downsamples 4K anyway. For square or vertical formats targeting mobile, 1080 by 1080 or 1080 by 1920 maximises screen real estate. Reserve 1080p landscape for desktop-heavy audiences like enterprise sales or executive education content.
Re-encode from source, not from a previous compression
LinkedIn re-encodes every uploaded video on its servers, which means starting from a previously compressed file gives the platform a degraded source to work from and the final played-back quality suffers. Always export the LinkedIn-bound version directly from your editing software or screen recorder. If you only have a previously compressed copy, accept that the LinkedIn version will be visibly softer than starting from a master, and tune your bitrate slightly higher to compensate.
Use a quality-targeting mode when size is not fixed
Since LinkedIn has a generous 5GB limit, you are rarely fighting a hard size cap and CRF encoding becomes ideal. CRF 20 produces near-master quality for important brand content, CRF 23 is the default for solid professional output, and CRF 26 is the line below which compression artefacts start to show on text overlays and gradients common in LinkedIn business content. Avoid going past CRF 28 for any LinkedIn upload, the perception of professionalism suffers visibly.
Verify audio sync after compression
LinkedIn videos autoplay silently in the feed, so audio sync issues are invisible to most viewers, but the moment someone unmutes and a 200ms lip-sync drift appears, the professionalism of the entire post drops. Check sync at the start, middle, and end of any video over five minutes. Also confirm audio loudness is reasonable, LinkedIn does not aggressively normalise like YouTube does, so an unnormalised mix sounds quiet against typical platform content.
LinkedIn recommends 1080p H.264 MP4
LinkedIn recommended settings: H.264 MP4, 1080p maximum, 30fps, AAC audio, under 5GB total, 3 seconds minimum and 10 minutes maximum for feed posts.
LinkedIn videos autoplay silently
LinkedIn videos autoplay muted in the feed. Add captions or on-screen text to communicate key points to viewers watching without sound.
Square format (1:1) performs well on LinkedIn
Square video (1:1 aspect ratio) takes up more feed real estate on mobile LinkedIn than 16:9 landscape. Consider compressing to 1:1 for feed posts targeting mobile professionals.
