About resizing to Instagram Portrait
Resizing to 1080 × 1350 changes the image's pixel dimensions, which also affects its file size. Shrinking stays crisp; enlarging beyond the original can look soft.
This preset is sized for Instagram Portrait. Everything runs locally in your browser, so your image stays private — no upload, queue or sign-up.
This sets your image to exactly 1080 by 1350 pixels, the 4:5 portrait ratio that is the tallest a feed post can be. Start from a 4:5 source so it isn't squeezed, then enjoy that portrait shots take up more vertical space than a square and catch the eye for longer as people scroll.
Frequently asked questions
How do I resize an image to Instagram Portrait?
Drag your JPG, PNG or WebP into the tool above — the size is already set to 1080 × 1350 pixels — and press Resize. FileTinker resizes it in your browser, then you download the result.
Will resizing to Instagram Portrait reduce the quality?
Resizing changes the pixel dimensions to 1080 × 1350. Scaling down stays crisp; scaling a small image up to 1080 × 1350 can look softer because there is no extra detail to add.
Does resizing keep the aspect ratio?
This preset resizes to exactly 1080 × 1350. On the main resizer you can lock the aspect ratio so width and height stay in proportion.
Are my images uploaded anywhere?
No. Resizing happens entirely in your browser — your image never leaves your device and nothing is stored on a server.
What is the best portrait size for an Instagram feed post?
The tallest allowed feed ratio is 4:5, which is 1080 by 1350 pixels. This tool outputs that exact size; going taller would make Instagram crop the top and bottom of your image.
