How to Use
- Click Select Image or drag and drop an image onto the canvas to load it.
- Once the image is loaded, a crop frame will appear automatically.
- Drag inside the frame to reposition it; drag the corner or edge handles to resize it.
- Use the Ratio buttons to lock the aspect ratio (Free / 1:1 / 4:3 / 3:4 / 16:9 / 9:16 / Custom).
- Custom ratio: Click Custom to reveal the ratio input fields. Enter any ratio (e.g. 3:2, 21:9) and click Apply.
- Pixel size: After loading an image, a pixel-size input row appears. Enter the width and height in pixels and click Apply. If the values do not match the selected ratio, the ratio takes priority and the crop dimensions are adjusted.
- Use the Rotate buttons to rotate the image in 90° steps; use the Flip buttons to mirror it horizontally or vertically.
- Use Zoom to adjust the display size (30%–300%). The output is always at the original resolution.
- Click Crop Image to generate a preview of the cropped result.
- Download the result as PNG, JPEG, or WebP. When JPEG or WebP is selected, a quality slider (10–100%) appears to balance file size and image quality.
- Keyboard: Focus the crop area and use the arrow keys to move it. Hold Shift and press an arrow key to adjust its size.
Notes & Specifications
- All image processing is done entirely in your browser. No data is sent to any server.
- Cropping is performed at the original image resolution, so output quality is always high.
- Large images are scaled down for display, but the exported file is at full resolution.
- Supported formats: JPEG / PNG / GIF / WebP (browser-dependent).
- Touch input is supported on smartphones and tablets.
- For JPEG and WebP, a higher quality value means better image quality (larger file size); a lower value means smaller file size (lower quality).
Frequently Asked Questions
- Q. Can I crop to a fixed ratio like 1:1 or 16:9?
- A. Yes. The Ratio buttons let you choose 1:1, 4:3, 3:4, 16:9, 9:16, Free, or Custom. With Custom you can enter any ratio (e.g. 3:2, 21:9), which is handy for SNS icons and thumbnails.
- Q. Can I set the crop size in pixels?
- A. Yes. After loading an image, width and height fields appear. Enter the pixel values and click Apply. If the dimensions conflict with the selected aspect ratio, the ratio takes priority and the crop dimensions are adjusted.
- Q. Does cropping reduce quality? Can I choose the format?
- A. Cropping is done at the original image resolution, so quality stays high. You can save as PNG, JPEG, or WebP. For JPEG/WebP, a quality slider (10–100%) balances quality and file size.
- Q. Are my uploaded images sent to a server?
- A. No. Loading, cropping, and saving all happen entirely in your browser, so your images stay private. Touch input on smartphones and tablets is also supported.
