How to choose my own PDF software?

Functional requirements: Consider your specific needs first. If you are simply viewing and reading PDF files, then a preview is sufficient. If you need more sophisticated editing and management capabilities, pdf editor freeAdobe Acrobat Pro may be a better fit. If you're a student or researcher, Skim might be a good choice. If you want to find a professional, fast and versatile PDF software on your Mac, UPDF is a good choice for you. Next, I will recommend the right PDF software for you through the functional requirements.

1. PDF reading

When reading PDF documents, people should be most concerned about the fluency of the document reading and the compatibility of the content of the PDF document. In terms of PDF opening speed, Preview is the fastest system software. However, since Preview is general-purpose software (you can view not only PDFS, but also images, TXT, Word, etc.), it also has compatibility issues. For example, comment content or body content may be lost, especially for PDF files where permission passwords (limited comments, edits, etc.) are less compatible. In terms of compatibility, Acrobat is the best choice, but due to the complexity of the software itself, in addition to the high performance requirements for Mac computers, opening and scaling documents may also require Cottonwood. I particularly recommend UPDF for reading core requirements. They combine the professional compatibility of PDF with the performance of preview. UPDF also has built-in Mac preview technology (which can be set up in UPDF Settings), which means UPDF stands out when viewing large documents, such as engineering drawings.

2. PDF notes

PDF annotation is an essential feature of every professional PDF reader or PDF editor. Although Adobe Acrobat is very comprehensive in terms of annotations, the overall experience and operation are relatively simple and cannot meet the richer needs of users for annotations.

Acrobat-Annotation tool Preview provides the basic annotation function, more precisely the annotation function, but as mentioned above, the compatibility is poor, especially when opening the annotated PDF with other PDF software, it is easy to lead to data loss.

Skim, a preview annotation tool, focuses on annotations that provide basic annotation functionality, but the overall look is clean and supports relatively few annotation types. This article recommends the UPDF software.

The Skim-annotation tool UPDF provides fast visualization operations as well as rich annotation presets, such as highlighting recommended colors. In particular, UPDF has redesigned and organized the various annotation categories and provides a note-taking function for each annotation to facilitate more detailed explanation. The overall design is closer to the way notes and notes are handled. In addition, UPDF provides comment management operations to facilitate the management of comment content in documents. If you have an in-depth need for taking notes in PDF, I highly recommend UPDF. UPDF supports notes: Post-IT notes, highlighted text, strikeout text, underlined text, wavy text, text notes, text box notes, text mark notes, pencil notes (eraser), rectangles, ovals, polygons, lines, arrows, rich stickers, business and office signatures, and signature actions.

3. PDF editing

When we talk about PDF editing, we usually mean editing the text and image content of PDF documents. For PDF native content editing, you really need to use professional PDF editing software. I recommend using AdobeAcrobat and UPDF in this regard. Previewing and browsing may not meet professional requirements, so they are not recommended for editing operations. Common PDF editors include non-scanning document editors and scanning document editors. This requires OCR functionality. Acrobat and UPDF both support OCR operations, and both support paragraph recognition and font matching operations, UPDF as a newcomer in the last two years, there are some gaps with Acrobat in text editing, but in the same PDF editing software, UPDF is still in the lead. The difference between the two kinds of software in PDF image editing is relatively small, both can support image addition, replacement, cropping and extraction operations, UPDF has outstanding performance in image addition and replacement, and supports direct drag and drop to add and replace pictures. In addition to the usual text and image processing, both support the movement and deletion of specific graphics (path elements) in a document, a feature not available in many other software. Both Acrobat and UPDF support editing and adding links to documents by adding jumps to pages or web pages.
