Supports JPEG, PNG, WebP
Crop images to exact dimensions or popular aspect ratios like 16:9, 4:3, 1:1 (square), and social media sizes. Preview your crop before downloading.
Cropping trims pixels off the edges of an image — simpler in concept than resizing, but every platform has different expectations for the final frame. Instagram posts want 1:1 or 4:5. YouTube thumbnails are 16:9. LinkedIn banners are 4:1. Apple App Store screenshots are tied to device aspect ratios. Doing this in a general-purpose editor means juggling guides and hoping you eyeballed the right area.
This cropper offers preset ratios for the common targets plus a free-form mode for exact pixel dimensions. You drag a selection box over the preview, and the output matches that selection exactly — no resampling, no quality loss, just a subset of the original pixels. Cropping is fundamentally lossless because you're discarding data, not transforming it.
Common cases include straightening a banner that's too tall, isolating a subject from a wide shot, creating a square avatar from a portrait photo, or preparing multiple aspect-ratio variants of the same hero image for different placements. Because the crop runs on your device, you can work with screenshots of internal dashboards, personal photos, or client work without uploading them to an external service.

Crop and download
Click crop to generate the output and download it. The original image isn't modified — only the cropped version is saved.
Social media squares
Turn a landscape photo into a 1:1 Instagram post or profile picture without buying a subscription to a full editor.
YouTube thumbnails
Crop a 16:9 frame from a wider screenshot or rendered image to match YouTube's thumbnail aspect ratio.
Banner straightening
Trim tall product photos into 4:1 or 3:1 banners for website headers, email campaigns, or LinkedIn pages.
Subject isolation
Cut out a specific area of a wide shot — a face, a detail, a region of a map — without scaling or distorting it.
Does cropping reduce image quality?
No. Cropping removes pixels outside the selection; the kept pixels are byte-identical to the source. The only quality change would come from a format re-encode, which this tool avoids unless you change format.
Can I crop to specific pixel dimensions?
Yes. Use the custom dimensions mode and enter exact width and height in pixels. The selection box snaps to match.
What aspect ratios are preset?
Common ratios for social media and web: 1:1 (square), 4:3, 16:9, 3:2, 4:5 (Instagram portrait), 9:16 (stories), and 2:1 (Twitter link preview).
Does it support PNG transparency?
Yes. Cropping a PNG or WebP with an alpha channel preserves transparency in the output.
Is my photo uploaded to a server?
No. All cropping happens on a canvas in your browser. The image never leaves your device.
