TikTok Carousel Size Checker
Check that your photo slides share one size and resize them for a TikTok photo post. Your images stay on your device.
Fill crops the picture around the middle. Fit keeps all of it and uses the background colour for the gaps. A JPG has no see-through areas, so it always gets a background.
How to use the TikTok Carousel Size Checker
- Choose one or more images. The checker lists each size and says whether it already matches.
- Pick the size you want. Choose Fill to crop to the edges, or Fit to keep the whole picture and add a background.
- Look at the previews and adjust the format, quality or background colour.
- Download each image, or all of them in a ZIP.

Good to know
- Sizes are the ones commonly recommended at the time of writing. Apps change them, so check the app's own help page if a size matters.
- Making a small picture larger cannot add detail, so start from a picture at least as big as the size you want.
Questions
Which size fills the screen?
9:16, 1080 × 1920 px. Keep text clear of the buttons and caption; use the TikTok safe zone checker for that.
Can I mix sizes?
It is better not to. Use one size for every slide so nothing is cropped unexpectedly.
Are my images uploaded?
No. They are resized in your browser and never sent anywhere.
