Frequently Asked Questions
Q.How do crop offsets work?▼
X is the horizontal distance from the left edge; Y is the vertical distance from the top. The crop starts at the (X, Y) point.
Q.Does cropping reduce file size?▼
Yes. Cropped images contain fewer pixels, resulting in smaller file sizes.
Q.Is my cropped image private?▼
Yes. PDFDock processes images entirely in browser memory. No data is transmitted over the network.
Q.Can I crop to specific aspect ratios?▼
You can manually calculate dimensions for common ratios like 16:9, 4:3, or 1:1 and enter them as width and height.
Q.What image formats can I crop?▼
JPEG, PNG, and WebP images are all supported for cropping.
