How it works

Square Crop lets you choose exactly which part of the photo to keep — everything outside the selection is discarded permanently in the downloaded file, so it's worth previewing the selection carefully before downloading. Because the crop works on the original resolution, the kept area stays as sharp as the source photo.

Tips for best results

Decide on the final aspect ratio before you crop so you don't have to redo it for a different platform.
Leave a little breathing room around the subject — you can always crop tighter later.
For faces, keep eyes roughly on the upper third of the frame for a natural-looking portrait.
Check the crop preview at actual size, since small crops can look different when scaled up.

Frequently asked questions

How is the square crop area determined?

Our tool takes the largest possible square from the center of your image. This ensures the main subject in the center is kept.

Can I choose where the square is positioned?

The square is automatically centered. To control composition, crop your image first using our Image Cropper then apply square crop.

What size is the output square?

The output size matches the shorter side of your original image. For example, a 1200x800 image produces an 800x800 square.

Is this the same as the Instagram Post Size tool?

Both create square images. The Instagram Post Size tool outputs a fixed size optimized for Instagram. Square Crop simply crops to 1:1 at your original resolution.

Does square crop work for profile pictures?

Yes. After square cropping, use our WhatsApp DP or other profile picture size tools to resize to the exact dimensions needed.

Can I crop to a custom size that isn't a preset?

Yes, you can set your own crop dimensions in addition to the common presets offered.

Does cropping reduce image quality?

Cropping itself doesn't reduce quality — you keep the original pixels for the area selected, just remove the rest.

Can I undo a crop and start over?

Yes, you can upload the original image again at any time to start with a fresh crop.
