What does a PDF reader need to do?
Start with your document: open it, search for a phrase, add a note, save a copy and reopen it. Check that the note is still editable and that the layout, links and form fields survive. A scanned page needs OCR before its image-based words become searchable.
What is included in Starix PDF Free?
Reading, search, printing, highlights and editable sticky notes have no time limit and need no account. For existing text editing, page organization, OCR, forms, signing or export, sign in and verify your email to claim a one-time 14-day Pro trial without a credit card.
When do you need a PDF editor?
Combining attachments, correcting references, organizing pages, OCR, redaction and export call for more than reading. Starix PDF Pro edits supported existing text, adds text boxes and crops or resizes pages locally. General edits support undo, without automatic paragraph reflow.
How Starix processes your documents
Starix processes core PDF reading, editing, OCR and export on your computer without requiring you to upload the PDF. Sign-in, payment and licence synchronisation use the internet; offline Pro use depends on the licence term.
How to try Starix with a real workflow

Try Pro with your own scans or export layouts before subscribing: OCR accuracy and converted layout depend on the source document. Keep the original file.
