PDF Tools for Teachers Prepping Handouts and Grading Scans

Between handouts, scanned assignments, and answer keys that shouldn't circulate freely, teaching generates a steady stream of small PDF tasks — almost none of which need anything beyond a browser tab.

Building handouts and packets

Combining a worksheet, a reading, and an answer sheet into one file for a class is a daily task for a lot of teachers. Merge PDF does it in the order you drag them into, and if a packet needs pages removed or reordered afterward, Organize Pages handles that without starting over.

Keeping answer keys from spreading

Marking a document as an answer key or draft — so it's obviously not meant for general distribution if a copy circulates beyond the intended group — is a quick job for Add Watermark, which stamps text like "ANSWER KEY" or "DRAFT" diagonally across every page.

Scanning and grading physical assignments

Turning a stack of handwritten assignments into a single PDF for grading or recordkeeping is what Scan to PDF is built for, using nothing more than a phone camera. If the resulting file is too large for a school's email or upload system, Compress PDF shrinks it while keeping handwriting legible at the lighter settings.

FAQ

Do I need a school-issued account to use these? No — there's no account of any kind. Anyone with a browser can use every tool immediately.

Will a watermark make an answer key unreadable if I do need to reference it? No — the watermark is a translucent diagonal overlay, designed to be visible without obscuring the content underneath.

Can I use this on a school-managed Chromebook? Yes — everything runs as a normal web page with no software to install, which works within most school device restrictions.
