How to Crop an Image
- Upload one JPG, PNG or WebP image by browsing or dragging it onto the page.
- Choose Free, a preset aspect ratio or a custom ratio. Move the selection and resize its corners to frame your subject.
- Check the original-pixel coordinates. Zoom in for a closer preview; zoom does not change your output dimensions.
- Choose an output format and, for JPG or WebP, quality. Click Crop Image, review the result and download it. Edit Again keeps your source ready for another crop.
Crop vs Resize
Cropping changes the framing by removing the edges outside your selection. Resizing scales the entire picture to different dimensions. A 1200 × 800 image cropped to a 600 × 600 square keeps just that selected square; resizing it to 600 × 400 retains the whole scene. Use Resize Image when you want to keep every part of the picture.
Aspect Ratios
Choose 1:1 for a square, 4:5 for a portrait, 3:2 for a photo, 16:9 for a landscape or 9:16 for a vertical composition. Custom Ratio accepts positive whole-number width and height values. Fixed ratios use whole-pixel multiples of the reduced ratio so the output stays exact. A ratio too large to fit the source at whole-pixel dimensions cannot be applied; choose a simpler ratio or Free.
JPG vs PNG vs WebP
JPG is useful for photographs and fills transparent areas with white. PNG keeps transparent edges and exports losslessly without a lossy quality slider. WebP supports transparency with adjustable quality. The default follows your source format. Your download uses the extension matching the actual encoded format. If file size is your main concern, try Image Compressor.
Privacy & Local Processing
Your image is decoded into its displayed orientation in browser memory, then the selected original pixels are encoded locally. No image upload, cloud processing or account is needed. Original EXIF, GPS and other metadata are omitted from the exported image. Keep your original if you need those details later.
Desktop limits are 64 MB per image, 24 megapixels and 16,384 pixels per side. Mobile and low-memory devices use stricter limits. A crop can also be rejected if source and output buffers exceed the device memory budget. A worker handles processing on supported browsers; a cooperative browser fallback is available. Verify local processing.
