Resize videos for Instagram, Facebook, YouTube, Twitter online

Kapwing's Resize Video tool is an online video resizer that you may use to create optimized videos for the popular services Instagram, YouTube, Facebook and Twitter.
While you can upload any captured video directly to any of the services, doing so may cut off part of the video. The services use different video ratios, and if your video happens to be in a different one, you may end up with black bars or parts of the video that are not visible after uploading it to one of the services.
Note: The videos that you create using the service have a watermark. You may remove it my linking your Google or Facebook account to the service, and by paying money for that.
The Resize Video editor works pretty much as you would expect it to. Upload a video to the service or point it to a video URL instead. Information about supported file types or the maximum video file size is missing unfortunately. You do get an error message however when you try to upload videos that are larger than 25 Megabytes.
The resize editor is loaded automatically after the video has been uploaded. It lists the supported services and the ratios of these services on the left.
You can only pick one out of the following services:
- Instagram -- ratio 1:1
- Instagram Snap Story -- ratio 9:16
- Youtube -- ratio 16:9
- Facebook or Twitter Portrait -- 4:5
- Facebook or Twitter Landscape -- 5:4
The preview changes automatically when you select one of the available presets. You may also switch from the default "fit" option to "crop" instead. Crop ensures that the video is without black bars, but some of it may be removed in the process.
If you keep the fit option, you may furthermore select a black or white background for the image.
Once you are satisfied with the selection, click on create video. This opens another page that highlights the processing progress in real-time. The processing itself was fast, and did not take longer than a minute for a 17 Megaybte video file.
The application displays options to download the video, or to open it directly in the browser.
Closing Words
The video resizing works really well, but Kapwing needs to work on the informational side of the service. Information such as the maximum upload size and supported file types, and that the video is watermarked, need to be visible on the starting page of the service.


Martin, I would appreciate that you do not censor this post, as it’s informative writing.
Onur, there is a misleading statement “[…] GIFs are animated images …”. No, obviously you don’t seem to have take much notice of what you were told back in March regarding; Graphics Interchange Format (GIF).
For example, https://www.ghacks.net/2023/03/31/whats-gif-explanation-and-how-to-use-it/#comment-4562919 (if you had read my replies within that thread, you might have learnt something useful). I even mentioned, “GIF intrinsically supports animated images (GIF89a)”.
You linked to said article, [Related: …] within this article, but have somehow failed to take onboard what support you were given by several more knowledgeable people.
If you used AI to help write this article, it has failed miserably.
AI is stupid, and it will not get any better if we really know how this all works. Prove me wrong.. https://www.youtube.com/watch?v=4IYl1sTIOHI
Martin, [#comment-4569908] is only meant to be in: [https://www.ghacks.net/2023/07/09/how-to-send-gifs-on-iphone-two-different-ways/]. Whereas it appears duplicated in several recent random low-quality non relevant articles.
Obviously it [#comment-4569908] was posted: 9 July 2023. Long before this thread even existed… your database is falling over. Those comments are supposed to have unique ID values. It shouldn’t be possible to duplicate the post ID, if the database had referential integrity.
Don’t tell me!
Ghacks wants the state to step in for STATE-MANDATED associations to save jobs!!!
Bring in the dictatorship!!!
And screw Rreedom of Association – too radical for Ghacks maybe
GateKeeper ?
That’s called “appointing” businesses to do the state’s dirty work!!!!!
But the article says itself that those appointed were not happy – implying they had not choice!!!!!!

Many Authors of bloggers and advertisers certified by Softonic have joined the site, and the site is full of articles aimed at advertising and clickbait.

As it stands, except for articles by Martin Brinkmann, Mike Turcotte, and Ashwin, they are low quality, unhelpful, and even vicious. It is better not to read those articles.

By the way, if you use an RSS reader, you can track exactly where your comments are (I’m an iPad user, so I use “Feedly Classic”, but for Windows I prefer the desktop app “RSS Guard”).
RSS Guard: Feed reader which supports RSS/ATOM/JSON and many web-based feed services.

We all live in digital surveillance glass houses under scrutiny of evil people because of people like Musk. It’s only fair that he takes his turn.
“Operating systems will be required to let the user choose the browser, virtual assistant and search engine of their choice. Microsoft cannot force users to use Bing or Edge. Apple will have to open up its iOS operating system to allow third-party app stores, aka allow sideloading of apps. Google, on the other hand, will need to provide users with the ability to uninstall preloaded apps (bloatware) from Android devices. Online services will need to allow users to unsubscribe from their platform easily. Gatekeepers need to provide interoperability with third-parties that offer similar services.”
Wonderful ! Let’s hope they’ll comply with that law more than they are doing with the GDPR.
