A practical toolkit
From opening a file to sending it back.
PDFs, ready for the next step
Highlight text, add annotations, redact content and organize pages. Combine documents or split a PDF into separate files.
Your signature, ready to reuse
Draw a handwritten signature or import it from a file. Keep it in your signature library and place it on a document when needed.
Optional cloud sync
Your signatures.
On your computers.
Connect Google Drive from the signature library to synchronize saved signatures between Proview installations. S3-compatible storage is also supported.
Google authorization is used only for signature synchronization. Proview requests the limited drive.file permission to manage files created by, or explicitly authorized for, the app. The default archive is proview/signatures in your Drive.
This sync does not upload the PDFs or images you open for editing. Cloud sync is optional; your local signature library works offline.
