Image Cropping FAQ
Answers to common questions about online image cropping on Prompts.Skin.
Are my images uploaded to a server?
No. Cropping runs entirely in your browser. Your files stay on your device and are never sent to our servers.
Which image formats are supported?
We support JPG, PNG, WEBP, GIF, BMP, HEIC, HEIF, AVIF, and TIFF. HEIC files are decoded locally before cropping.
What crop ratios are available?
Free (unconstrained), 1:1, 4:3, 16:9, and custom width/height. The crop box shows rule-of-thirds guides for better composition.
How do ID photo presets work?
Each preset sets the crop aspect ratio and exports at standard pixel dimensions (300 DPI). For example, 1-inch is 295×413px and civil service is 413×579px.
Can I set a custom aspect ratio?
Yes. Select Custom and enter width and height values. The crop box locks to that ratio while you adjust position and size.
Will cropping reduce image quality?
Cropping itself does not add compression artifacts. Output uses high-quality Canvas export. ID presets resize to exact pixel dimensions as required by upload systems.
Do I need to register or pay?
No. The image cropper is completely free with no sign-up required.
