Crop an image to 4:5
Crop photos to the 4:5 portrait ratio — the tallest format Instagram allows in the feed — with a locked selection and live preview, entirely in your browser.
Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.
Why 4:5 is the Instagram power ratio
A 4:5 portrait post occupies the maximum vertical space Instagram’s feed allows — about 25% more screen than a square and nearly double a landscape shot. More screen means more time in front of eyes. Cropping to exactly 4:5 yourself, instead of letting the app do it, decides what stays in frame.
Crop versus resize
Cropping cuts a 4:5 window out of your photo at full resolution — you choose the framing by dragging. If you’d rather keep the entire image and pad it to 4:5 instead, the resize tool’s Fit mode with a blurred background does that. Both previews show precisely what you’ll export.
Frequently asked questions
- Is my image uploaded to crop it?
- No. Cropping, rotating, flipping and straightening all run locally in your browser.
- Can I crop to a specific aspect ratio?
- Yes. Choose Free, 1:1, 4:3, 3:2 or 16:9 and the crop selection snaps to that ratio.
- Can I rotate or straighten a tilted photo?
- Yes. Rotate in 90° steps, flip horizontally or vertically, and fine-tune a crooked horizon with the straighten slider.
- What format is the cropped image saved in?
- The original format is preserved wherever possible (BMP files are saved as PNG).
