Frequently Asked Questions

Does cropping affect image quality?
The tool uses Canvas API for high-quality image cropping, maintaining good image quality in most cases. Cropped images maintain original resolution range, no significant quality loss. If cropped image size is small, enlarging may produce some blur. We recommend using PNG or WebP format output for best quality.
Will my images be uploaded to the server?
No, all processing is done in your browser. Your image files never leave your device, completely protecting your privacy.
How large images can I crop?
The tool supports images up to 20MB. For very large images, we recommend first using image compression tool to reduce file size, then cropping. During processing, you can view progress to keep track of status. Cropped image dimensions have no limit, depending on original image size and crop area selection.
