How to Resize Images for the Perfect Instagram Post
Instagram is picky about aspect ratios. If your photo is too tall or too wide, it will cut off the important parts. Tulz ensures you fit the frame perfectly.
Why is this needed?
A professional-looking feed requires consistent, high-quality images that aren't blurry from poor scaling.
!Step-by-Step Instructions
Choose your Post Type
Select between Square (1:1), Portrait (4:5), or Story (9:16).
Upload and Adjust
Upload your photo. Our tool will show you a preview of how it will look in the app.
Download and Post
We export at the exact pixels Instagram recommends (e.g., 1080x1350 for portrait) to prevent compression artifacts.
Pro Tips
- •Portrait (4:5) is scientifically proven to get more engagement because it takes up more vertical space on the screen.
- •Check our [Background Remover](/tools/image-background-remover) if you need a cleaner aesthetic for your product photos.
Frequently Asked Questions
Why does Instagram make my photos blurry?
If your file is too large (over 1080px width), Instagram's own compression can be very aggressive. Resizing it yourself first prevents this.
Can I resize Stories?
Yes! Use the 9:16 preset to ensure your story doesn't have black bars on the top and bottom.
