What does this tool do?
The preview is scaled to fit your screen, but the crop is applied to the original full-resolution image, so you don't lose quality. Rule-of-thirds guides help you frame the subject.
Why use it?
- Square crops for profile pictures.
- 4:5 and 9:16 for social posts and stories.
- Remove distracting edges.
Which ratio for what?
1:1 for profile photos, 4:5 for Instagram feed posts, 9:16 for stories and reels, 16:9 for YouTube thumbnails and presentations, 3:2 for standard camera prints.

Frequently asked questions
How do I crop a photo to a specific size?
Choose a preset ratio (1:1, 4:5, 16:9 and more) or a free crop, then drag the box over the part you want to keep — the exact pixel size updates as you drag. For a fixed output size such as 600 × 600 px, resize the cropped image with the Image Resizer.
How do I crop a profile picture into a circle?
Crop to 1:1 here, then use Add Border & Rounded Corners to make it a circle with a transparent background.
Does cropping reduce quality?
No. Cropping only removes pixels outside the box — the kept area stays at its original quality.
Are my photos uploaded?
No. Everything happens in your browser using the Canvas API. Your images never leave your device, which is why it works even on a slow connection.
Which aspect ratio should I use for social media?
1:1 suits profile pictures and square posts, 4:5 is a common portrait size for feeds, 9:16 is for stories and short videos, and 16:9 is for YouTube thumbnails and presentations. Check each platform's current guidance, as it changes from time to time.
