Frequently Asked Questions


Q01: What is PDF?

A: Short for Portable Document Format, a file format developed by Adobe Systems. PDF captures formatting information from a variety of desktop publishing applications, making it possible to send formatted documents and have them appear on the recipient's monitor or printer as they were intended. To view a file in PDF format, you need Adobe Reader, a free application distributed by Adobe Systems.

Q02: What is OCR?

A: OCR stands for Optical Character Recognition. It is the process by which we convert your physical books into an editable text-based file format such as Word, TXT, HTML, etc. (Please note, PDF files are image-based, and thus do not depend on OCR accuracy. However, the PDF files will contain an OCR text layer behind the images to make the text searchable and selectable).

Q03: What is the best scanning resolution for OCR?

A: Most OCR engines, including the ones used by Advanced PDF Utilities Free, are optimized for 300 dpi images. Scanning at true 300 dpi optical resolution is very important. Scanning at a lower resolution and then using scanner software to increase the dpi later on does nothing for OCR. In cases where the font size of characters on an image are very small (point size of 4 or less), scanning images in at 400 dpi can improve character recognition. This again would require a scanner that supports true 400 dpi optical resolution.

Q05: Why does it take so much time for the PDF to Image conversion?

Q07: Why some parts of PDF document are replaced by strange characters in plain text output?

A: Sometimes when fonts are embedded or subset within a PDF, the original font information is lost and the text is corrupted. Although PDF Acrobat or Reader will still display correctly, the correct text information is not available. In these cases PDF-to-Text failed to extract the correct text from your file.

Q10: What is the advantage of using Free PDF Merger over an online service?

A: Three words: Security, speed, and size! With online services, you need to upload files to a server, which at times may not have the necessary security features in place to protect confidential PDF documents. With a desktop application, every part of the merge is done on your computer with no file size restrictions or security issues. In addition, running merges from your personal computer/laptop does not require an internet connection, which makes the process much faster than online PDF file merging.

Q11: How do I convert a scanned document?

A: Scanned PDFs contain only the image of text, rather than actual text. OCR is necessary to analyze the image and create editable text. Free Image OCR features an optional OCR module for editing your scanned documents, or PDF's that otherwise convert as image only. With the OCR module, Free Image OCR can convert immediately to any of the output formats available, such as .doc, .txt, image formats, and more. Using Free Image OCR to edit a scanned file in Word or TXT, as well as scan directly to PDF or Word is incredibly easy.
