Crop Image for Instagram

Instagram's algorithm rewards images that fit one of three aspect ratios cleanly: square (1:1), portrait (4:5), and story / reels (9:16). Posting any other ratio means letterboxing, awkward auto-cropping, or your photo getting hidden behind 'tap to expand'. SnapToolz' image cropper has all three Instagram presets locked in — you load your photo, pick the format, drag the crop box where you want it, and download. The crop runs in pure JS Canvas so there's no upload, no waiting, and your originals stay intact.

Frequently asked questions

• What's the best aspect ratio for the Instagram feed?

  4:5 portrait. It takes up more screen real estate than 1:1 squares and ranks better in the algorithm because users spend longer on it.

• What dimensions does Instagram actually use?

  The display dimensions are 1080×1080 (square), 1080×1350 (portrait), and 1080×1920 (story). The cropper exports at those exact sizes.

• Will Instagram re-compress my image?

  Yes — Instagram always re-compresses uploads. There's no avoiding it, but starting with a properly-cropped, sharp image gives the best result.

• Can I crop multiple photos at once?

  The cropper handles one image at a time because the crop frame is interactive. For batch resizing, use the Image Resize tool instead.
