Presentation
PDF4Teachers is specifically designed for teachers. It allows you to annotate assessments returned in PDF with excellent productivity.
PDF4Teachers provides tools for editing PDF files productively while annotating/correcting assessments. It memorizes all previously added annotations and offers quick insertion of them. PDF4Teachers also supports the definition of a grade scale (numerical or competency-based grading). Grades can then be exported as a .csv spreadsheet.
PDF4Teachers can also perform batch conversion of images to PDF to convert multiple documents at the same time. A lot of other PDF tools are also available, including booklet assembler/disassembler, PDF merge and split, move and rotate pages, and more.
PDF4Teachers supports freeform drawing, vector SVG path elements, images, LaTeX and LibreOffice Math equations.
PDF4Teachers saves any edits made to a PDF file as a separate layer, so the original PDF remains intact (except for any changes made with PDF tools). You can export the edited document as a new PDF file within the app.
