Crop Images
Crop images online with preset ratios (1:1, 16:9, 9:16) or freeform selection. Free, fast photo cropper that works offline in your browser, no uploads.
About This Tool
Crop your images with precision using our interactive crop tool. Select a freeform area or lock to popular aspect ratios like 1:1 for Instagram, 16:9 for YouTube thumbnails, or 9:16 for Stories and Reels. The crop box is fully draggable and resizable, giving you complete control over the final composition. Processing happens entirely in your browser, your image never touches a server.
How To Use
- Upload an image by dragging it into the drop zone or clicking to browse.
- Choose a preset aspect ratio or use freeform for complete flexibility.
- Drag and resize the crop box to select exactly the area you want to keep.
- Click "Crop" to process and download your cropped image.
How It Works
The crop tool displays your image with an interactive overlay that you can drag and resize. When you select a preset aspect ratio, the crop box locks to that proportion, you can still resize it, but width and height will always maintain the chosen ratio. In freeform mode, you have complete control over both dimensions.
When you click Crop, the tool uses the Canvas API's built-in createImageBitmap function with crop coordinates to extract exactly the pixels within your selection. This is then drawn onto a new canvas matching the crop dimensions and exported in the same format as your original image at maximum quality.
The crop coordinates are calculated relative to the image's natural dimensions, not the display size on screen. This means you always get the full resolution of the cropped area, regardless of how large or small the image appears in your browser window. The processing happens in a Web Worker, though for a single crop operation it's near-instantaneous.
Frequently Asked Questions
Can I crop multiple images at once?
The crop tool handles one image at a time because each image needs individual crop area selection. For batch operations with fixed dimensions, use the Resize tool instead, which can process up to 50 images at once.
What aspect ratios are available?
We offer Freeform, 1:1 (Square), 16:9 (Widescreen), 4:3 (Standard), 3:2 (Photo), and 9:16 (Story/Reel). These cover the most common use cases for social media, print, and web.
Does cropping reduce image quality?
No. Cropping extracts the exact pixels from your original image at full resolution. There is no recompression or quality loss. The output maintains the same quality as the original file.
Can I undo the crop?
You can adjust the crop area as many times as you want before clicking the Crop button. After processing, use the "Do another file" button to start over with the original image.
What's the maximum image size?
You can crop images up to 50MB in size. The interactive crop overlay works smoothly even with high-resolution images because it operates on a scaled display version while preserving full-resolution coordinates.
Is my image uploaded anywhere?
No. The crop tool runs 100% in your browser. Your image is processed locally using the Canvas API and never leaves your device. It works perfectly offline after the page has loaded.
