Introduction
Open Instagram, Facebook, or LinkedIn in 2025, and what do you see? Videos, videos, and more videos! Reels, stories, ads, explainers… everything’s moving

But here’s the tricky part: not all videos fit perfectly everywhere. A clip that looks perfect on Instagram Reels might get squished on LinkedIn. A Facebook ad that plays smoothly could have text cut off on Instagram.

And let’s be honest, it’s frustrating.

Even worse, sometimes platforms compress your video automatically. That gorgeous 4K edit you worked so hard on, suddenly it looks blurry and low-quality.

The solution, Simple. Use the right video size for each platform, and before uploading, run it through a tool like Tekedge online video compressor to keep your file light but sharp.

Why Video Size Still Matters (Yes, even in 2025)
You’d think by now, platforms would just handle all this for us. But nope, get the size wrong, and your video suffers.

It might look blurry.
It might load slowly.
Or worse, the algorithm quietly buries it because it isn’t “optimized.”
Audiences ...
... don’t have patience. If the video lags, they scroll. If text is cut off, they scroll. If it doesn’t fill the screen right, they scroll.

That’s why marketers, influencers, and even casual creators are obsessed with getting sizes right. And why do so many people quietly compress their files first with something simple like Tekedge video compressor. It saves time, avoids ugly compression from the platforms, and keeps the video looking professional.

Instagram Video Sizes in 2025
Instagram has fully leaned into video. If you’re posting there, here’s what to know:

Reels — Vertical (9:16), 1080 × 1920 px, up to 90 seconds.
Stories — Same size as Reels, 15 seconds per clip.
Feed videos — Square (1080 × 1080), Vertical (1080 × 1350), or Landscape (1080 × 608).
If you’re after reach, vertical wins every time. Instagram pushes it.

But heads up, longer Reels can get heavy in file size. Uploading a 500 MB Reel? Painful. I’ve done it. It crawls. Compress it first with an online video compressor like Tekedge, and suddenly it’s 10× faster to upload without the quality tanking.

Facebook Video Sizes in 2025
Facebook’s still huge for video, especially for ads and groups. Here’s the breakdown:

Feed videos — Landscape (16:9), Square (1:1), or Vertical (4:5). Best if under 2 minutes.
Stories — 1080 × 1920 px, 20 seconds max.
Ads -Square or vertical works best for mobile.
The tricky part with Facebook is speed. Heavy files = endless buffering = annoyed audience. I once had an ad rejected because the file was too big and wouldn’t process. Since then, I just compress first. Tekedge video compressor has been a lifesaver, it trims the size while keeping the video sharp enough to run as a paid campaign.

LinkedIn Video Sizes in 2025
LinkedIn is different. People are there to learn, not to be entertained with memes (well, mostly). Videos that work here are crisp, professional, and to the point.

Here’s what to stick with:

Feed videos — Horizontal (1280 × 720), Square (1080 × 1080), or Vertical (1080 × 1350).
Max file size: 200 MB.
Best length: 30 seconds to 3 minutes.
Ads — Square or horizontal, at least 1080 px. Keep them under a minute.
Here, quality matters more than anywhere else. A pixelated or cropped video screams “unprofessional.” Which is why I never skip compressing before uploading. A quick run through an online video compressor keeps the file small enough for LinkedIn’s limits but still crisp for an executive audience.

Mistakes I See All the Time
Even now, creators and marketers keep tripping up:

Uploading massive videos and letting platforms destroy them with auto, compression.
Putting text too close to the edges, only to see it chopped on mobile.
Re, using the same file everywhere (Instagram ≠ LinkedIn).
Forgetting to check file size, then waiting 20 minutes for a video to upload.
The fix is boring but effective: check the size, compress if it’s heavy, then post. Honestly, using something like Tekedge video compressor has saved me from so many embarrassing moments.

Why I Recommend Tekedge
Look, there are a million tools out there. But what I like about Tekedge is that it’s:

Browser based (no downloads, no logins).
Fast (it doesn’t take forever to compress).
Private (files don’t leave your computer).
Flexible (handles MP4, MOV, AVI, all the usual suspects).
It’s not fancy, but it works. And when you’re juggling Instagram Reels, Facebook ads, and LinkedIn explainers, that’s exactly what you need, something reliable.

Final Thoughts
Videos are the language of social media in 2025. But the small technical stuff, like the right size and the right file weight, makes the difference between a video people watch and one they scroll past.

Instagram loves vertical. Facebook’s flexible but rewards smaller files. LinkedIn demands professionalism. And across all three, a quick pass through a online video compressor keep’s things smooth.

So before hitting upload, do the boring prep work. Get the size right. Compress the file. Then post with confidence.

Your content deserves to look its best, don’t let a heavy file or wrong format ruin it.
