Frequently Asked Questions
Does cropping reduce image resolution?
Cropping removes outer pixels outside your selected area while preserving 100% of the original sensor clarity within the cropped region.
Can I crop photos to standard social media dimensions?
Yes. Use 1:1 for Instagram profile avatars, 16:9 for YouTube thumbnails or banner headers, and 4:5 for vertical feed photos.
Are my photos uploaded to external servers?
No. All pixel cropping executes client-side in browser RAM using Canvas APIs; files never touch remote cloud storage.
Is this Image Cropper safe and private to use?
Yes. All processing happens 100% locally on your computer inside your web browser using client-side JavaScript. Your files and data are never sent to any external server.
