Crop images online — free or fixed ratio
Drag a crop box anywhere on your image, or lock it to ratios like 1:1, 4:5 and 16:9. Rotate, flip, use the rule-of-thirds grid, and preview circular crops — all locally in your browser.

How it works
- 1
Add an image
Drop, pick or paste — the crop box appears immediately.
- 2
Frame your crop
Drag the box or its handles, lock an aspect ratio, or type exact pixel dimensions. Rotate and flip first if needed.
- 3
Check composition
The rule-of-thirds grid helps balance the frame; circular preview shows how avatars will look.
- 4
Apply and download
Export as PNG, JPG or WebP.
Common uses
- Squaring a photo for a profile picture
- Cutting distractions out of a product shot
- 16:9 crops for thumbnails and presentations
- 9:16 vertical crops for stories and reels
- Trimming whitespace from screenshots
- Preparing 4:5 portrait posts
Cropping and aspect ratios
An aspect ratio is the relationship between width and height — 1:1 is square, 16:9 is widescreen, 4:5 is the portrait shape most feeds favor. Locking a ratio while you drag guarantees the output matches the destination's shape exactly, so nothing gets auto-cropped later by the platform.
Cropping is also a compositional tool: the rule-of-thirds grid divides the frame into nine parts, and placing your subject along those lines usually reads better than dead center.
Good to know
- Rotation is in 90° steps (plus horizontal/vertical flips) — free-angle rotation isn't included yet.
- Cropping animated GIFs outputs a single still frame.
- The circular preview shows how round avatars will look; the exported file itself stays rectangular (with transparency if you export PNG).

Frequently asked questions
Does cropping reduce image quality?
No — cropping removes pixels outside the box but doesn't recompress what remains beyond one encode of the output. Export as PNG for zero generational loss, or JPG at high quality for photos.
How do I crop a perfect circle?
Platforms apply the circular mask themselves, so what you actually need is a well-centered square crop. Lock the ratio to 1:1, turn on circular preview to check the framing, and export. For a full avatar workflow with backgrounds and multiple sizes, use the Profile Picture Maker.
Can I crop to exact pixel dimensions?
Yes — type the width and height into the numeric fields and the box resizes precisely. Combine with an aspect lock to keep the shape while adjusting the size.
Does this work on a phone?
Yes. The crop box, handles and panning all use touch-friendly pointer events, and the numeric fields are there when you need pixel-exact control on a small screen.
