PDF - Crop Mark Sign

About this app

PDF - Crop Mark Sign is a focused, native PDF editor for macOS. Open a PDF, trim it down to the page size you need, mark up the important parts, and drop your signature in the right place — all from one clean window. Every edit happens on your Mac. Nothing is uploaded, nothing is tracked. FEATURES ◆ Crop to Standard Page Sizes Crop any page to A4, A5, Letter, Legal, or B5 with a preset — or draw a custom crop rectangle. Apply the crop to the current page only, or to every page in the document. Toggle "Preserve Content" to keep text and images intact, and reset a crop at any time. ◆ Multi-Colour Highlighting Select text in the PDF and highlight it in yellow, green, blue, orange, or red. See a running count of highlights on the current page. Remove highlights from the current page or from the entire document in one click. ◆ Draw or Import a Signature Sign PDFs by drawing your signature with the trackpad or mouse, adjusting stroke width and colour before you save. Prefer a photo of your signature? Import an image and the app will offer to automatically remove the white background, leaving only the ink. ◆ Precise Signature Placement Set the exact width and height of your signature in points, then drop it anywhere on the page. Your saved signatures stay in a library ready for the next document. ◆ Page Info & Word Count The Select tool shows page dimensions in points and inches, word count for the current page and the whole document, plus live counts of annotations and highlights as you work. ◆ Full Page Navigator A thumbnail sidebar on the left lets you jump between pages instantly. A tool sidebar on the right keeps Select, Crop, Highlight, and Sign one click away. ◆ Undo, Redo, Save Every change is undoable and redoable. Save back over the original file, or use Save As to export a new PDF — your choice. ◆ 100% On-Device No accounts. No servers. No analytics. No ads. All PDF editing happens locally on your Mac. Your documents — contracts, IDs, legal forms, anything — never leave your computer. ◆ Native macOS App Built natively for macOS with a clean, familiar interface. Drag and drop a PDF to open, or use the file picker. Light and dark mode supported.
