Edit PDF Guides & Tutorials
How to Add Page Numbers to PDF
Adding page numbers to a PDF makes documents easier to navigate and reference. Whether it's a report, manuscript, or legal document, SublimePDF lets you add customizable page numbers in seconds.
How to Convert Scanned PDF to Text
Scanned PDFs are essentially images — you can't select or search the text. OCR (Optical Character Recognition) technology converts these image-based PDFs into searchable, editable text. SublimePDF's OCR tool handles this conversion right in your browser.
How to Fill Out a PDF Form Online
Many important forms — tax documents, applications, contracts — come as PDF files. SublimePDF lets you fill them out directly in your browser without printing, handwriting, and scanning.
