Practical, in-depth tutorials on getting the most out of your PDF files — written to be useful whether or not you use our tools.
PDFs are everywhere, but they can be frustrating to work with: files that are too big to email, scans you cannot search, documents locked in a format you cannot edit. These guides explain how each problem happens and walk you through solving it step by step. Each one is free to read, with no sign-up required.
A scanned document is really just a picture of text, which is why pressing Ctrl+F finds nothing. This guide explains what OCR is, how it turns those pictures back into searchable words, and how to find any term inside a scanned file in seconds.
OCR · SearchingNeed to know how many times a part number, invoice code or reference appears across a long scanned document? Learn how to locate every occurrence of a code with OCR and get an accurate count, even when the text lives inside images.
OCR · CountingWhen you need to edit a contract clause or update an old report, you need an editable file — not a fixed PDF. This guide covers how PDF-to-Word conversion works, what to expect from the formatting, and when OCR is needed for scanned pages.
ConversionMost email services cap attachments at around 20–25 MB. Learn why PDFs get so large, which parts you can safely shrink, and how to compress a file enough to send without making it unreadable.
CompressionA behind-the-scenes look at how the tools process your files, what happens to a document after you upload it, and the privacy principles that shape the whole service.
