What is the TikTok video size?

1080x1920 pixels, a ratio of 9:16. It is the whole screen. Photo mode uses a shorter frame instead, which is why the two are listed separately here.

What if my image is not 1080x1920?

It uploads and is padded out to fill the screen, leaving bars. Nothing is refused, but a clip with bars is visibly a repost and it is competing against videos that fill the frame.

Is my image uploaded when I check it?

No. The file is opened by your own browser, measured, and forgotten when you close the tab. It is never sent to us, so there is nothing on our side to keep, leak or delete.

Can I post a landscape video to TikTok?

Yes, and it will play inside bars in the middle of the screen. That costs you most of the display and marks the clip as something made elsewhere. If the footage only exists in landscape, it is usually worth reframing the important part into a vertical export instead of posting the full width.

Yes. This tool does its work in your browser, so whatever you type, paste or upload stays on your device. Nothing is sent to our servers, which is also why it keeps working if you go offline after the page has loaded.

Yes. Every tool here is free with no account, no credit card and no usage cap. They exist so that the people who need our scheduling product find us, which only works if the tools are genuinely useful on their own.

Do I need an account?

No. Open the page and use it. An account is only for OctoSpark itself, where you plan, schedule and publish a whole calendar rather than fixing one post at a time.

Can I use the output commercially?

Yes. Anything you produce here is yours, including for client and commercial work. We claim no rights over it and we do not watermark it.

TikTok video size

The TikTok video size is 1080x1920 pixels, a ratio of 9:16. Check a frame in the browser and see what the interface covers along the right edge and bottom.

Every TikTok video size

Every TikTok video size, with its pixels, its ratio and what it is for.
Where it is used	Pixels	Ratio	What the number is for
Video frame	1080x1920	9:16	Full screen, and the size a cover frame is shown at.
Photo post	1080x1440	3:4	Shorter than the screen, used by photo mode.
Profile photo	200x200	1:1	Drawn as a circle beside every video you post.

Every TikTok video size, in pixels

TikTok is a full-screen surface with its own interface drawn on top, so the frame below is the whole story right up until you ask which part of it is free of buttons.

Video frame: 1080x1920px, a ratio of 9:16. Full screen, and the size a cover frame is shown at.
Photo post: 1080x1440px, a ratio of 3:4. Shorter than the screen, used by photo mode.
Profile photo: 200x200px, a ratio of 1:1. Drawn as a circle beside every video you post.
The action column runs up the right-hand side and the caption sits across the bottom, both over your video rather than beside it.
Video is re-encoded on upload, so an enormous file gains nothing. The frame shape is what matters, not the bitrate you started from.
A photo post is shorter than the screen, which means a photo post and a video cover are not interchangeable exports.
The cover frame doubles as the tile on your profile grid, where it is shown small and cropped, beside dozens of others.

Check a file you already have against the TikTok video size

What people usually hold here is footage shot on a phone in the wrong orientation, or a cover exported at a square size from a design tool. Either way the question is how much of the frame survives.

Pick the target first. This page carries 3 TikTok video sizes, and a verdict only means something against one of them.
Choose your image. It is opened by this browser tab and measured on a canvas, so the file never leaves the machine you are sitting at and there is no queue or upload to wait for.
Read the result: an exact match at 1080x1920, the same 9:16 shape at a different scale, or a crop with the axis that loses pixels named.
If it is wrong, open the TikTok resizer linked underneath. It exports to these exact numbers instead of leaving the decision to the platform.
Keep the subject in the middle column, clear of the right-hand buttons and the caption, since those are drawn over the frame at whatever size you upload.

What TikTok does when the shape is wrong

TikTok accepts a video of any shape and pads it out to fill the screen, which is the most visible size mistake on any platform here: bars above and below announce that the clip came from somewhere else.

A landscape video is shown as a small strip in the middle of the screen with large empty bands around it.
A square video leaves shallower bands and still reads as a repost lifted out of a feed.
A cover whose text sits low is hidden by the caption during playback and cropped on the profile grid, so it is lost in both places.

Where the frame stops being the problem

Getting the frame right is table stakes on TikTok and achieves nothing on its own. What happens to a video is decided in its first second or two, which is a question about the opening shot rather than about pixels.

Bars around a reposted video carry a real cost, because they look like a repost. Re-export at the full frame rather than fixing the cover alone.
Captions burned into the very bottom of a video sit behind the platform caption, so lift them into the middle band.
A cover is scanned rather than read. One face or one object beats a sentence every time at grid size.

The rest of the job

You just fixed one post. Now do the month.
