Features & Capabilities

PDF/HWP text search, bookmarks

Cropper for PDF/HWP/PNG is a fast, focused tool for reading PDFs and copying exactly the areas you need - problems, figures, tables, paragraphs - straight to the clipboard.

Open any PDF, double-tap to enter crop mode, drag a box around the region, and tap the center to copy. The image lands on your clipboard at the original PDF quality, ready to paste into Notes, Pages, Keynote, your messaging app, or any document editor.

Built originally for math teachers and students working with worksheets and exam papers, Cropper for PDF works just as well for anyone who needs to lift a clean snippet out of a long document.

Doesn’t work- waste of time.

Goodness gracious chungkil Kim! You only had one job in this app and you screw it up! Let me ask you a simple question, if you crop a pdf why would you want to end up with a PNG file in the end?? People who crop pdf want to have a cropped pdf! It’s that simple. Also why not include function to rotate the cropped PDF (not png) and a function to be able to save the newly cropped pdf file! It’s simple stuff, man! And you want someone to pay for this after two weeks lol. I’ll pay for it to be taken off my phone. Good luck buddy!

The controls to use the crop feature are intuitive and you can’t scroll through your PDF while you’re trying to crop. This app is a bust.
