How to Annotate a PDF Without Uploading It
Reviewers often annotate PDFs in cloud tools that store copies on vendor servers. PDFSnap keeps highlights, comments, and drawings on your device only.
Open PDFSnap EditorWhat “client-side annotation” means
Client-side annotation loads the PDF into your browser, renders pages locally, and saves markup layers in memory until you export.
PDFSnap does not persist your files on backend storage. Closing the tab removes in-session data unless you download the updated PDF or use browser-local recent document storage.
Common annotation workflows
Contract review: highlight key clauses, add margin comments, export for counsel.
Form completion: place text answers and checkmarks without printing and rescanning.
Design feedback: draw arrows and notes on spec PDFs before sharing exports you choose to send.
Combine annotation with other PDFSnap tasks
After annotating, you can merge the marked PDF with appendices or split out signature pages — all with the same local-only workflow.
