Help & Frequently Asked Questions

Common Questions About Image Resizer & Cropper

Answers to common questions about features, privacy, and browser-side workflows.

Does cropping degrade the original photo resolution?

No! The crop tool operates directly on the original resolution buffer. You can export pixel-perfect crops without lossy blur.

What is the advantage of saving as WebP?

WebP is Google's next-generation format that delivers up to 90% smaller file sizes than JPEG while keeping sharp edges and rich colors.

Are my private photos uploaded to any external server?

Never. The crop operation runs strictly in your computer or phone RAM using the HTML5 Canvas API.

Can I crop images for passport and visa applications?

Yes! Select the 1:1 Square or 4:5 Portrait preset to crop standard visa and passport photos with millimeter precision.
