These are the widely used Instagram upload sizes. Instagram can change its crops, so check your own export size if a preset looks off.

Why Instagram images need resizing for Pinterest
Instagram posts are mostly square or 4:5 portrait, while a standard Pinterest pin is 2:3, which is taller. If you upload an Instagram post as is, Pinterest shows it shorter than the pins around it, and it takes up less space in the feed. Resizing an Instagram image for Pinterest is about adding height without stretching or chopping off the important part.
The converter below handles that in your browser. Drop in a post, story or carousel slide, pick a Pinterest size and choose how to fill the extra space. Blur fill extends a square photo into a tall pin with a soft blurred copy behind it, which keeps the whole image visible. Crop works well for 4:5 portraits, which only lose a slice from each side.
Tips for converting Instagram images
Square posts: use blur fill
Cropping a 1080 square to 2:3 removes a third of the width, which often cuts off people or products at the edges. Blur fill keeps the full square and adds a soft background above and below, leaving room for a title.
4:5 portraits crop cleanly
A 4:5 post is already tall, so cropping to 2:3 removes only about one sixth of the width. Slide the focus control to keep faces or products centered.
Stories map to tall pins
Stories and Reel covers are 9:16. Choose the Tall pin size to keep them intact, or crop to 2:3 if the important content sits in the middle.

Instagram to Pinterest FAQ
How do I resize an Instagram image for Pinterest?
Upload the image above, select the Standard pin size and pick blur fill for square posts or crop for 4:5 portraits. Download the result as a JPG or PNG. Everything happens in your browser, nothing is uploaded.
Can I post a square Instagram image on Pinterest?
Yes, Pinterest accepts square images. They simply appear shorter in the feed than 2:3 pins. Converting to 2:3 with blur fill gives the image more presence and space for a title.
Will resizing reduce quality?
The converter scales the image to the chosen size. If your original is smaller than the target, it is enlarged, which can soften it slightly. Starting from the largest export of your post gives the sharpest result.
