Image Cropper: free online image cropper

Crop away unwanted edges or focus on a particular part of a photo. Enter the crop rectangle in pixels and export the selected area in a supported image format.

When to use image cropper

Cropping is useful for thumbnails, profile photos and image layouts where the subject needs a specific framing.

How to use this image cropper

Choose an image, enter the left and top positions and crop width and height, then click Crop Image. Keep the crop rectangle inside the original dimensions.

1. Select the correct your source file file from your device.
2. Choose the available output settings that match your intended use.
3. Start the conversion and keep the browser tab open while processing finishes.
4. Download the the required format result and open it to confirm that it looks right.

Common uses and practical examples

An image cropper removes unwanted edges and focuses attention on a subject. Cropping is useful for profile photos, article thumbnails, product images and layouts with a fixed frame. This tool uses pixel coordinates for the crop area, so the left and top values locate the starting point and the width and height define the area to keep.

Output quality, format and compatibility

The crop rectangle must remain within the original image dimensions. If the width or height extends beyond the source, the operation may fail or produce an unexpected result. Cropping does not increase resolution; a very small crop may look soft when enlarged. Preview the result at its intended display size and keep the original so you can try another framing if needed.

Coordinates are measured from the top-left corner. Cropping cannot add detail outside the original image.

Tips for better results

For thumbnails and profile images, keep the main subject away from edges that may be clipped by a circular mask or responsive layout. If the crop must match a specific aspect ratio, calculate the target dimensions before exporting. Use a format that suits the destination and check whether transparency is required. A cropper changes the visible area; it does not remove the background or retouch the image.

Privacy and browser-based file processing

For supported operations, processing happens in your browser and the tool does not intentionally upload your selected file to this website. Some document features depend on JavaScript libraries loaded from a content delivery network, so an internet connection may be needed to load those libraries. Browser processing still uses your device memory and processor; very large files may take longer or fail on older devices. Use a trusted device for sensitive work and remove downloaded copies from shared computers when finished.

Troubleshooting conversion problems

If the tool does not accept a file, check that its actual format matches the filename extension and that the file opens normally in another application. A damaged, encrypted, unusually structured or very large file may not process successfully. Refresh the page, use an up-to-date browser and try a smaller sample if needed. Network restrictions, privacy extensions or a firewall can block a required library from loading. If the output downloads but looks wrong, repeat the conversion with suitable settings and compare it with the original.

Frequently asked questions about image cropper

How do I crop an image?

Choose an image, set the crop coordinates and dimensions, then click Crop Image.

What are crop coordinates?

Left and top describe the crop area’s starting point from the image’s top-left corner.

Can I crop to JPG or WebP?

Yes. Choose a supported output format before cropping.

Will cropping improve resolution?

No. It selects part of the image and does not create missing detail.

Are images uploaded?

Cropping happens in your browser and the selected image is not intentionally uploaded.

A simple checklist for reliable results

Before you start, confirm the receiving website or application accepts the output format and check any stated file-size or dimension limits. Choose a source file that opens correctly, then use the settings offered on this page rather than changing the filename extension manually. After processing, download the generated file and open it independently. For images, inspect sharpness, colours, transparency and dimensions. For documents, check page order, text, tables, headings and page breaks. If the output is intended for a formal submission, compare it against the original and follow the recipient’s instructions. These quick checks help prevent common problems such as uploading the wrong format, sending an unreadable page or using a file that exceeds an upload limit.

Choosing the right tool for the next step

Different file tasks can sound similar but produce different results. Converting a format changes how the file is encoded; resizing changes image dimensions; cropping removes part of an image; compression aims to reduce file size; and creating a PDF places content into a document container. PDF-to-image conversion produces a page picture, while PDF-to-Word aims to make text editable and may need formatting corrections. Select the tool based on the result you actually need, not only the file extension. If this page does not offer a required feature such as batch processing, OCR, transparent-background removal or detailed page editing, use a specialised workflow rather than expecting a basic converter to perform it automatically.
