1What is Crop Image?
Crop images with precision.
Crop Image is part of the Pixly suite of professional image tools. It runs entirely in your browser with no software to install, requires no design experience, and delivers results in seconds — whether you are processing one image or an entire batch. Every operation is applied on the full-quality decoded image, so the output preserves the fidelity of your original file.
2How does Crop Image work?
Cropping extracts the exact pixel rectangle you specify: an X/Y offset from the top-left corner plus a width and height. The engine validates the rectangle against the image bounds (clamping rather than erroring when you drag near an edge), then copies that region into a new buffer — no resampling happens, so cropped pixels are a perfect, unmodified copy of the original.
EXIF orientation is applied before the crop math, meaning the coordinates you choose correspond to what you see on screen, not to the raw sensor orientation some phones store.

9Frequently asked questions
Does cropping reduce quality?
No. Pixels inside the rectangle are copied unchanged — quality only changes later if you re-encode to JPEG at a lower quality.
