About Perspective Crop
Photos of documents, whiteboards and signs are often shot at an angle, so the rectangle leans and the edges look stretched. A plain crop cannot fix that slant; it just trims a tilted picture, leaving text skewed and hard to read.
Perspective Crop lets you mark the four corners of the area you want and straightens it into a flat, head-on rectangle, removing the distortion as it crops. Set the corners, apply, and download a clean, square-on result. The processing happens in your browser on ToolHub by Codaiman, so your image stays on your computer. It is free, needs no registration, and adds no watermark.

FAQ
How is this different from a normal crop?
It warps the four corners you select back into a straight rectangle, fixing angle distortion rather than just trimming edges.
What do I need to do?
Place a marker on each of the four corners of the area you want straightened, then apply.
Will text become more readable?
Usually yes. Removing the slant makes angled text and lines look flat and straight.
Does my image get uploaded?
No. The correction runs in your browser and the file is not sent anywhere.
Can I use Perspective Crop on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
