YouTube GIF comments: make your own GIF from a video
Pick the moment, add a caption, choose a size limit, and download a looping GIF.
YouTube is adding GIFs to comments in its mobile app. The GIFs come from a library inside the app, so a reaction made from your own clip has to be published there first. This tool makes that GIF: trim up to 10 seconds, add top and bottom text, loop it forward or back and forth, and keep it under the file size you choose. Your video stays on your device.

Up to 10 seconds. Short loops of 2 to 4 seconds make the best reactions.
To use it in a YouTube comment: publish it on Tenor, add a tag nobody else uses, then search that tag in the GIF picker. See using your own GIF below for what is and is not confirmed.
How to make a reaction GIF from your own video
1. Choose your video
Any clip your browser can play: a phone video, a screen recording, a moment from your own upload. It is read by your browser and never sent anywhere.
2. Find the moment
Drag Start to the beat you want and set the length. Play the clip to check the loop, with your captions drawn on top.
3. Pick size and speed
Choose the width, the frame rate, square or as filmed, the speed, and whether it loops forward or back and forth.
4. Make and download
Set a file limit if you need one. If the first try is too big, it makes the GIF narrower until it fits, and tells you the width it used.
How to post a GIF comment on YouTube
YouTube showed GIF comments at its Made on YouTube event on September 23, 2026, and began rolling them out in the mobile app in mid October. Reports describe it reaching accounts gradually, with some people able to see GIFs before they can post them.
Update the YouTube app on your iPhone, iPad or Android phone.
Open the comments under a video or a Short and tap the comment box.
Choose a GIF from the GIF option, if your account has it, and post.
YouTube's own developer changelog for the comments API added a field on September 30, 2026 for "an image or animated GIF attached to a comment", and says it "will be available to all users in November 2026". That entry is about comment data, so read it as a strong hint about timing rather than a promise that every account gets the button that month.
As of October 30, 2026, the reporting says GIF comments come from a library inside the app, and it is not confirmed that you can attach a file from your phone. Many guides say that library is Tenor's, Google's GIF service. We could not confirm that from YouTube itself, so treat the route below as the likely one, not a guarantee.
Make the GIF here and download it.
Upload it on Tenor's upload page with a tag nobody else uses. On October 30, 2026 that page took GIF, MP4, PNG and JPG files, up to 10 at a time. It did not state a file size limit or a review time.
Search your tag in YouTube's GIF picker once Tenor shows it. If it does not appear, Tenor may still be reviewing it, or it may not be rated for every audience.
What makes a GIF small
Width matters most. Halving the width leaves about a quarter of the pixels in every frame.
Frames come next. Twice the frame rate, or twice the length, is about twice the file. Back and forth adds the frames again in reverse, minus the two ends.
Busy footage costs more than a still background, because GIF compression works best on long runs of the same colour.
Speed costs nothing. 2x keeps the same frames and shows each one for half as long.
Limits, in numbers
Video: up to 2 GB, any length, in a format your browser can play.
Clip: 0.5 to 10 seconds, at 8, 10, 15 or 20 frames per second, so at most 200 frames, or 398 with back and forth.
Size: 240, 320, 480 or 640 pixels wide, never wider than the video itself. With a file limit set, it can go down to 120 pixels wide to fit.
Colour: up to 256 colours per frame, the most a GIF frame can hold, chosen for each frame separately.
Captions: up to 60 characters each, white with a black outline, shrunk to fit the width.
Questions, answered
Is my video uploaded?
No. Your browser plays the video, draws each frame to a canvas and builds the GIF on your device. The first time you press Make GIF, the open-source encoder (gifenc) loads from cdn.jsdelivr.net; that is a download, and nothing of yours goes with it. The counter under the upload box shows how many bytes of request body left the page while you worked.
Can I upload my own GIF straight into a YouTube comment?
As of October 30, 2026, reports describe GIFs coming from a library inside the YouTube app, and it is not confirmed that you can attach your own file. Many guides say the library is Tenor's, so publishing your GIF on Tenor is the likely way in. We could not confirm that from YouTube itself.
Why don't I have the GIF button?
YouTube is turning it on gradually, account by account, in the mobile app. Update the app and check again later. YouTube's API changelog says GIF and image attachments in comment data reach all users in November 2026.
Can I post a GIF comment from a computer?
YouTube has described the feature in its mobile app. As of October 30, 2026 we found no official word on GIF comments on youtube.com in a desktop browser. You can make the GIF here on a computer and post it from your phone.
Can I paste a YouTube link instead of a file?
No. This works on video files on your own device. It does not download videos from YouTube or any other platform. To point someone at a moment of any YouTube video without copying it, a Playback loop repeats that part in YouTube's own player and shares as a link.
What are the limits?
Videos up to 2 GB in any format your browser can play. Clips of 0.5 to 10 seconds at 8 to 20 frames per second, 240 to 640 pixels wide, never wider than the video. A file limit of 1, 2 or 5 MB makes it narrower until it fits, down to 120 pixels wide, and the page tells you if even that is too big. Each frame holds up to 256 colours.
Is there a watermark?
No. Nothing is stamped on your GIF, and there is no account or sign-up. The only mark is the file name, which starts with ThumbCrafted.
