Compress Video for LinkedIn The 5 GB cap is not your problem

LinkedIn accepts video files up to 5 GB on a feed post, so almost nothing you would actually publish is too big. What stops posts is the length cap, a codec LinkedIn cannot process, and the minutes a heavy file spends uploading from a laptop or a phone. This page sets out the real limits per surface and gives you a 1080p H.264 MP4 that LinkedIn handles without argument. It compresses and can cap resolution, nothing else: no trimming, no reframing. Your browser does the encoding, so the video never reaches us at all.

  • 1080p H.264 MP4
  • Nothing uploaded
  • Up to 20 clips

MP4, MOV, M4V, MKV, AVI, WebM, WMV, TS, MTS, MPEG, 3GP, FLV and more

Up to 20 videos at once

Privacy-first No uploads Processed locally

Your video is processed in your browser's memory and never uploaded, so the ceiling is set by your device, not by us.

Strong compression with a widely compatible MP4 for CMS and portfolio uploads.

Privacy-first. No uploads. If this helps, share it.

Bigger files? Run it in the Cloud

This tool runs on this device for free. For a file over the device limit or a long video, the same tool runs on our servers, with up to 5 GB per file and 6 hours of video, faster, and with your files kept for up to 7 days, or as long as you choose with any pack or plan. From 1 credit a minute, with 10 credits free when you create an account.

  • Unannounced work stays on your machine

    The encoder is FFmpeg compiled to WebAssembly and it runs inside this page. A launch teaser under embargo, an internal demo or a recruiting clip nobody has approved yet goes to LinkedIn from your own hands and passes through no one else on the way.

  • The one combination no LinkedIn page argues with

    The preset this page starts on writes H.264 at CRF 26 with the shorter side of the frame capped at 1080p and 96 kbps AAC audio into an MP4. LinkedIn's organic and advertising spec pages disagree about plenty, but every one of them accepts that.

  • A campaign's worth of clips in one pass

    Assets rarely ship alone. A talking head cut, a customer quote and a product demo can queue together, up to 20 files at 1.75 GB each. The queue runs in sequence rather than in parallel, since the browser build is single threaded, so a big batch wants a laptop and a bit of patience.

Quick answer

How to compress a video for LinkedIn

A feed post allows up to 5 GB and up to 15 minutes, so you compress for upload speed and playback reliability rather than to squeeze under a cap. Add the clip, keep the preset the page loads with, and you get a 1080p H.264 MP4 with AAC audio that moves quickly and processes cleanly on LinkedIn's side. Nothing is sent to a server here. The only upload is the one you make on LinkedIn.

  1. Add the video
  2. Keep the loaded preset
  3. Upload the MP4 to LinkedIn

What LinkedIn actually enforces, per surface

Size is the generous number. Length, container and frame shape are where posts get refused, and the numbers move depending on where the video lands. An asset that posts fine from a personal profile can still be ineligible as a sponsored ad.

Where it goesDocumented limitsWhat that means for you
Feed post, personal profile5 GB, 15 minutesSize is a non issue, 75 KB is the only floor. Length is the wall. Feed autoplay is muted, so the opening seconds have to work with no sound.
Company or Career Page5 GB, 10 minutesSame size ceiling, five minutes less room. A 12 minute talk that posts from your profile is refused from the Page, and no amount of compression changes that.
Video ads, Sponsored Content500 MB, MP4 onlyLinkedIn's ad specs page lists 75 KB to 500 MB, 3 seconds to 30 minutes, AAC or MPEG4 sound below 64 KHz, 30 fps as the recommended frame rate and captions as optional.
Frame, ratio and bit rate256x144 to 4096x2304LinkedIn's video sharing page gives the same block: aspect ratio 1:2.4 to 2.4:1, 10 to 60 fps and 192 Kbps to 30 Mbps. Ads are narrower and ask for set shapes such as 16:9, 1:1, 4:5 and 9:16.
After you uploadRe-encoded either wayLinkedIn re-encodes every upload into its own H.264 renditions before anyone sees it. It does not publish which one a given viewer receives, so a heavier master buys upload minutes rather than better playback.

LinkedIn's own help pages do not always agree with each other, and specs change quietly, so read this as a snapshot rather than a contract. Last verified on 16 August 2026.

Conflicting numbers

LinkedIn's specs contradict LinkedIn's specs

Three numbers are worth knowing before you trust a guide. On file size, a 100 MB limit turns up on LinkedIn's media file types page, but it sits in a general notes block next to document limits like 300 pages and a million words, and the same 100 MB appears on the page about media on your profile, which does not cover video. Every LinkedIn page that is actually about video, the video sharing page and the Pages spec page alike, says 5 GB. On length, the video sharing page lists a flat 15 minute maximum with a 3 second minimum on desktop and 2 seconds in the app, the Pages spec page says 10 minutes, and a lot of writing online reports a 15 minutes on desktop, 10 minutes in the app split that LinkedIn does not state anywhere. On ads, many guides still quote a 200 MB ceiling while LinkedIn's own advertising spec page says 75 KB to 500 MB.

When two LinkedIn pages disagree, build to the smaller number. A video under 10 minutes, in an MP4, with H.264 and AAC inside, clears every version of the spec at once.

Phones

The phone problems that look like file problems

Plenty of uploads that never finish have nothing wrong with the video. LinkedIn states that videos stored on iCloud are not supported for upload on the mobile app, and that on iOS you need to stay in the app because the upload can stall if LinkedIn goes to the background, while Android keeps uploading behind other apps. Both failures look the same from outside: a progress bar that stops. A smaller file shortens the window in which either can happen.

  • Move an iCloud video into local phone memory before you try to post it from the LinkedIn app.

  • On iOS, keep LinkedIn in the foreground until the post is live. On Android the upload continues in the background.

  • Viewers control autoplay themselves. The mobile setting offers never, Wi-Fi connections only, or mobile data and Wi-Fi, so part of your audience sees a still frame.

Get a LinkedIn ready MP4 in three steps

Nothing leaves the browser at any point.

  1. 01

    Add your video

    MP4, MOV, MKV, AVI and WebM all go in, by drag and drop or through the file picker. The batch ceiling is 20 files at 1.75 GB each, which covers webinar exports, edited case studies and pieces to camera shot on a phone.

  2. 02

    Keep the preset the page loads with

    It re-encodes to H.264 at CRF 26 with the shorter frame side capped at 1080p and 96 kbps AAC audio, and it sets no size target, so quality leads. Running the file as an ad instead? Switch to Custom, set a target that tries to stay under 500 MB and keep 1080p.

  3. 03

    Download it, then upload to LinkedIn

    You get an H.264 MP4 with AAC audio. Check the running time against the cap for the surface you are posting to, and check the frame shape, because this tool changes neither: it cannot shorten a video or alter its aspect ratio.

Why compress for LinkedIn when 5 GB is allowed

Not to fit a limit. To stop paying upload time for detail LinkedIn re-encodes away, and to remove the codec problems that make a finished upload fail at the processing stage.

Your master is not the file that reaches viewers

Every upload goes through a processing stage that re-encodes it into LinkedIn's own H.264 renditions, so the file you send is not the file that plays. LinkedIn does not publish what resolution or bitrate a viewer is served, and its Videos API returns different rendition labels for different assets, so there is no fixed number to design against. What is clear is that a 4 GB master and a well made 1080p H.264 file both arrive as LinkedIn's re-encode, and only one of them costs you an hour of uploading.

Upload time is the cost you actually pay

A multi gigabyte file is a long transfer on whatever connection you happen to be using, and that transfer is the window in which conference Wi-Fi drops, a laptop sleeps or an iPhone gets pushed to the background and stalls. Shrinking the file shrinks the window.

H.264 in an MP4 is the path that processes

LinkedIn says a ProRes file may upload and then be unable to process, and lists MPEG-2, raw video, VP6 and WMV1 among the types it does not support. Re-encoding to ordinary 8 bit H.264 with AAC removes that failure mode before you hit post.

One export that also clears the ads bar

Sponsored Content is MP4 only and capped at 500 MB, far below the organic ceiling. If a clip might ever be promoted, a modest 1080p H.264 MP4 from the start saves a re-export when the campaign brief arrives.

Publishing the same clip elsewhere too? See the Instagram or X compressor.

Privacy

A draft post is unpublished work

LinkedIn video tends to be a launch teaser, a customer story with a named logo, an all hands recording cut down for public use or a hiring pitch that has not been announced. Handing that to an upload based converter before the announcement is a poor trade for a file the platform re-encodes anyway.

This page compresses through WebAssembly in the browser itself, so there is no transfer to us, no server side copy and no account holding a history of what you processed. Shut the tab and there is nothing on our side to delete.

What that means in practice

  • The file is uploaded once, by you, to LinkedIn
  • Your footage, its file name and its metadata never reach us
  • No watermark, no account, no export limit
  • Your own CPU does the encoding, so a 12 minute talk is not instant

Frequently asked questions

5 GB for a feed post from a personal profile or a Page, with a 75 KB minimum. Video ads are the exception at 500 MB. A 100 MB figure also circulates. It comes from LinkedIn's media file types and profile media pages, where it sits among document and image limits, so read it as covering profile and document uploads. Every LinkedIn page written about video says 5 GB.
