To crop an image to a 1:1 aspect ratio for free, open the omnikitbolt Crop tool, select the 1:1 preset, drag the crop box over the part of the image you want to keep, and download. The crop box locks to 1:1 so the proportions are always exact. Everything runs 100% in your browser — no upload, no signup, no watermark — and cropping removes only the pixels outside the frame, so there is no quality loss.
Open the omnikitbolt Crop tool and drop your image in. Supports JPEG, PNG, and WebP.
Choose the 1:1 ratio. The crop box locks to 1:1 — drag and resize it over the area you want to keep.
Download your perfectly cropped 1:1 image instantly. Everything stays in your browser — nothing is uploaded.
1:1 is an aspect ratio — these are the pixel sizes people most often export after cropping. See the full 1:1 pixel dimensions table.
| Use | Pixels (W × H) |
|---|---|
| Instagram square | 1080 × 1080 |
| Profile picture | 320 × 320 |
| Album cover | 3000 × 3000 |
Center your subject before cropping to 1:1 — square crops draw the eye straight to the middle of the frame.
For profile pictures, leave a little headroom; most platforms display the square inside a circle and clip the corners.
Common square export sizes: 1080×1080 px for Instagram, 320×320 px for avatars, 3000×3000 px for album covers.
Cropping a wide or tall photo to 1:1 trims the long edge equally on both sides — reframe if your subject is off-center.

Use the Crop tool to crop your image to 1:1, or browse all aspect ratios.
Open the omnikitbolt crop tool, choose the 1:1 ratio, and the crop box locks to a square. Drag it over the part you want to keep and export — the result is a perfectly square image.
Instagram displays square posts at 1080×1080 px. Crop to 1:1 and export at 1080×1080 for the sharpest result. Instagram still supports square even though 4:5 portrait now takes more feed space.
Yes — almost every platform uses a square (1:1) source for profile photos, then masks it into a circle. Crop to 1:1 with a bit of margin around the face so nothing important gets clipped by the circular mask.
No. Cropping removes pixels outside the square but leaves the kept pixels untouched, so there is no quality loss. Only upscaling a small crop to a larger size would soften the image.
Crop to 4:5
The tallest format Instagram allows in the feed — perfect for portrait feed posts (1080×1350 px) that take up maximum screen space, plus Pinterest and portrait layouts.
Crop to 16:9
The widescreen standard — perfect for YouTube thumbnails and videos (1280×720, 1920×1080), presentation slides, desktop wallpapers, and any 16:9 display or player.
Crop to 9:16
The full-screen vertical standard — perfect for Instagram Reels and Stories, TikTok, YouTube Shorts, and Snapchat (typically 1080×1920 px).
Crop to 4:3
The classic standard — perfect for traditional photography, iPad and tablet screens, older monitors and TVs, and many presentation templates.
