NightOwl PDF: edit, sign and search PDFs in your browser

Merge, compress, edit, sign, redact and make PDFs searchable, in Hindi, Marathi and English. Your documents are worked on in your own browser. Scans can be read fast on our server in India, and the pages are never stored; in Private mode nothing leaves your computer.

Are my files safe?

NightOwl is built for confidential files, including other parties’ documents. Here is exactly where each kind of work happens.

On this device

Opening, viewing, editing, redacting, merging, splitting, compressing and adding passwords run in your browser, and so does the free OCR unless you choose our server. The file is not uploaded.

When a page leaves your device

Save to account stores the PDF and your work in your private account (Supabase, Mumbai), until you delete it. Reading scans on our server sends each scanned page as an image to NightOwl’s server in Mumbai, which reads it and keeps nothing. High-accuracy OCR sends a scanned page too unclear to read here as an image to Google Cloud Vision to read; NightOwl does not keep it. Private mode turns all three off.

Redaction that removes

Redacted text and pictures are deleted from the file you export, not just covered, and checked for before it is saved.

No recordings, no ads
