Image Resizer & Cropper Guide
Resizing and cropping images is essential for web content optimization. Large images slow down page loads; cropping removes unwanted edges to focus on the subject.
Use the drag-select rectangle over the image to crop, then enter target width/height to resize. Choose PNG for transparency or JPEG for smaller file size.
This tool processes everything locally within your browser using the HTML5 Canvas API. Your original image file is never transmitted over the internet.
Frequently Asked Questions (FAQ)
Q: Is the image uploaded to your server when I crop or resize it?
A: No. All processing is done entirely on your device using JavaScript and the Canvas API. No image data is ever sent to any server.
Q: What is the difference between PNG and JPEG output?
A: PNG supports transparency and is lossless, resulting in larger file sizes. JPEG compresses the image with adjustable quality, producing smaller files but loses some detail at lower quality settings.
Q: Can I crop the image to an exact aspect ratio?
A: Yes. Use the mouse to drag the crop selection over the area you want to keep. Then set your desired width and height. The "Maintain Aspect Ratio" checkbox will preserve proportions when you modify either dimension.
Q: What file formats are supported for input?
A: Any image format your browser supports: JPEG, PNG, GIF, BMP, WebP, and SVG. If your browser can display it, you can crop and resize it.
