TikTok Carousel Ad Specs: Image Sizes and Export Checklist
TikTok carousel ad specs list horizontal images at 1200x628 pixels, square images at 640x640 pixels and vertical images at 720x1280 pixels. Use JPG or PNG, with a suggested file size of 100 KB or less, then check each exported card before uploading.

Start with the carousel image requirements, not the settings for a video ad. TikTok publishes separate specifications for carousel ads, so a video export preset is not a substitute for checking your image files. This guide covers the listed image dimensions, formats and suggested file weight, followed by a practical preparation workflow. Treat the creative advice below as a production checklist, not additional TikTok requirements.
| Item | Specification | Preparation note |
|---|---|---|
| Horizontal image | 1200x628 pixels | Compose the card for a wide canvas, then inspect the crop. |
| Square image | 640x640 pixels | Check that the product and headline remain clear after export. |
| Vertical image | 720x1280 pixels | Arrange the subject and text for a tall canvas. |
| Image format | JPG or PNG | Check the exported file format, not just its filename. |
| Suggested image file size | 100 KB or less | This is a suggested target, not a stated hard upload maximum. |
TikTok Carousel Ad Specs: Image Sizes and Export Checklist
Choose the image layout before designing
Pick horizontal, square or vertical and set your canvas to the corresponding dimensions in the table. As a workflow choice, use a consistent layout across the set so you can compare cards easily. Do not stretch an existing image to fit: adjust the composition or crop while keeping the product's appearance accurate.
Write a short card-by-card brief
Give each card a clear purpose before making the artwork. For example, introduce a product, show a useful detail, explain how it fits a buyer's routine and close with the next action. This is an illustrative sequence, not a required card count. Keep factual claims tied to what the product actually does.
Make or adapt the images
Use your existing design editor if the artwork is already finished. If you need new artwork, Infinall AI can create images from a prompt on Free and Pro. Pin a confirmed brand to the Studio project to use its name, colours, voice and logo in image creation and edits. Review the result rather than assuming generated details are correct.
Resize and inspect each export
The TikTok Ad Resizer is the matching free tool for preparing carousel image dimensions. Use it to resize artwork for the layout you selected, then save JPG or PNG files. Inspect the actual exports for cropped labels, distorted products and unclear text. Check file weight against TikTok's suggested 100 KB target, while preserving enough detail for a readable card.
Review the full set before uploading
Read the cards in their intended order and compare their wording with the destination page. Check dimensions, format and file weight for every exported image, not only the opening card. Infinall AI lets Free and Pro users download finished work without spending credits. Prepare the files there if useful, then handle the carousel ad setup in TikTok's advertising tools.
Pixel dimensions and file weight are different checks
A correctly sized canvas does not tell you whether the export is a JPG or PNG, or how much storage it uses. Check these properties separately. TikTok's carousel specifications list the image dimensions and suggest a file weight of 100 KB or less. Do not present that suggestion as an absolute upload rejection threshold.
If reducing file weight makes a product label unreadable, simplify the design and compare another export. Avoid adding decorative detail that competes with the product. Keep an editable version so you can change the crop or wording without repeatedly working from a compressed image.
Do not borrow rules from another TikTok format
Use the carousel help page for carousel image requirements. TikTok's auction in-feed video specifications and reservation ad caption guidance describe different placements. Do not automatically apply their video duration, bitrate, caption limits or safe-zone measurements to this image set.
Before final setup, consult TikTok's carousel documentation for the ad variant you intend to use. This guide does not assign a card-count limit, music requirement or caption maximum where those details are not established here. Keeping format-specific requirements separate is more useful than treating every TikTok ad as the same asset.
Check claims as well as the crop
Meeting the image specifications is only part of preparation. TikTok's misleading and false content policy restricts false expressions and exaggerated information, and disallows absolute terms about a product in relation to time, region or brand. Review headlines and image text for claims you cannot support.
TikTok also restricts product-effect comparisons, including before-and-after results, that could create a false or distorted impression. A series of cards can imply a transformation even without stating it in a headline. Review the meaning of the whole sequence, not just the wording on each image.
When an existing editor is the better choice
If you already have approved artwork and only need the correct dimensions, a resizer or your current design editor is the more direct choice. Generating replacement artwork adds review work and can change product details you meant to preserve.
Infinall AI fits earlier in the process when you need images made or edited from your brand. Making images uses credits; pinning a brand and downloading finished work do not. Use the resulting artwork as creative material to inspect and prepare, not as proof that TikTok will approve the ad.
Frequently asked questions
What size should a TikTok carousel ad image be?
TikTok lists horizontal images at 1200x628 pixels, square images at 640x640 pixels and vertical images at 720x1280 pixels. Choose the layout you are preparing and inspect each exported card at its listed dimensions.
Which image formats do TikTok carousel ads use?
The carousel image specifications list JPG and PNG. Confirm the output format after exporting, rather than renaming a file extension and assuming the underlying format has changed.
Is 100 KB a hard file-size maximum?
The carousel image guidance describes 100 KB or less as suggested. Treat it as a preparation target, not as a confirmed hard maximum. Check TikTok's carousel help page and your upload flow before finalizing the files.
Can Infinall AI help prepare carousel artwork?
Yes. Free and Pro users can create images and pin a confirmed brand to an image project. Image creation uses credits, while downloading finished work is free. Use the TikTok Ad Resizer for the matching dimensions and check the final exports before setting up the ad.
