How to crop a photo to a specific aspect ratio
Load an image and choose a ratio chip — 1:1 for profile photos and Instagram squares, 16:9 for thumbnails and presentations, 9:16 for Stories, 4:3 or 3:2 for classic prints. The selection box stays locked to that ratio while you drag any corner, so the crop always matches the target shape exactly. Free mode removes the lock for arbitrary rectangles. The live readout under the canvas shows the real output size in pixels before you commit.
Crop without losing quality
Cropping is a lossless geometric operation on the pixel data: the tool extracts exactly the region you selected from the full-resolution original — not from the on-screen preview — so a crop from a 4000px photo retains its native sharpness. The preview you drag on is a scaled display copy; the math maps your selection back to source coordinates before extraction. JPG output is re-encoded at 92% quality; PNG and WebP sources keep their format.
Private, in-browser cropping
Everything happens on your device. The photo is decoded, displayed, cropped and re-encoded by your own browser — nothing is uploaded, which makes this safe for ID documents, screenshots with personal data, and unreleased work. It also means cropping is instant: there is no upload wait and no server queue regardless of file size.
Frequently asked questions
Does cropping reduce image quality?
No. Cropping removes pixels outside your selection but does not resample the pixels you keep. The crop is taken from the full-resolution original, so the kept region stays exactly as sharp as it was.
How do I crop a picture into a square?
Select the 1:1 ratio chip, then drag and position the locked square selection over the area you want. The output is a perfect square at whatever resolution your selection covers.
Is my photo uploaded anywhere?
No. The cropper runs 100% in your browser — the image never leaves your device, making it safe for documents and private photos.
Can I crop to exact pixel dimensions?
The live readout shows the output size in pixels as you drag. For an exact target like 1080×1080, crop with the matching ratio first, then pass the result through our Image Resizer for precise dimensions.
Which ratio should I use for a YouTube thumbnail?
16:9 — YouTube thumbnails are 1280×720. Crop at 16:9 here, then resize to exactly 1280×720 with the Image Resizer if your crop is larger.
