How to choose my own PDF software?

Functional requirements: consider your specific needs first. If you just view and read PDF files, then previewing is enough. online pdf converter merge compressIf you need more complex editing and management functions, Adobe Acrobat Pro may be a better choice. If you are a student or a researcher, degreasing may be a good choice. If you want to find a professional, fast and multifunctional PDF software on your Mac computer, UPDF is your good choice. Next, I will recommend the appropriate PDF software for you through functional requirements.

1. PDF reading

When reading PDF documents, people should be most concerned about the smoothness of the document reading and the content of PDF documents compatibility. convert merge pdf to single pdfPreview is the fastest system software in terms of PDF open speed. However, because previews are generic software (you can view images, TXT, Word, and so on, as well as PDFS) , there are compatibility issues. For example, comment content or body content may be lost, especially in PDF files that are not compatible with permission passwords (limited comments, editing, etc.) . 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 of a Mac, opening and zooming documents may require catwood. I particularly recommend reading the core requirements for UPDF. They combine the professional compatibility and preview capabilities of PDF. UPDF also has built-in Mac preview technology (which can be set in UPDF settings) , which means that UPDF stands out when viewing large documents such as engineering drawings.

2. PDF notes

PDF annotation is the basic function of every professional PDF reader or PDF editor. word to pdf converter free download offlineAlthough Adobe Acrobat is very comprehensive in annotation, its overall experience and operation are relatively simple, which can not meet users' needs for richer annotations.

The Acrobat annotation tool Preview provides basic annotations, or more precisely annotations, but as mentioned above, compatibility is poor, especially when opening annotated pdfs and other PDF software, it is easy to lose data.

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 browse annotation tool UPDF provides quick visualizations and rich annotation presets, such as highlighting recommended colors. In particular, the Ugandan People's Defence Forces has redesigned and organized the various annotation categories and provided a recording function for each annotation to facilitate more detailed interpretation. 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 comments in documents. If you have an in-depth need to take notes in PDF, I highly recommend UPDF. UPDF supports annotations: publish its annotations, highlight text, delete text, underline text, wavy text, text comments, text box comments, text mark comments, pencil comments (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 the editing of PDF native content, professional PDF editing software is really needed. I recommend using AdobeAcrobat and UPDF in this respect. Preview and browse may not meet the professional requirements, and editing is not recommended. Common PDF editors include non-scanning document editors and scanning document editors. This requires the OCR function. Acrobat and UPDF both support OCR operation, and both support paragraph recognition and font matching operation. As a newcomer in recent two years, UPDF has some gaps with Acrobat in text editing, but UPDF is still in the leading position in the same PDF editing software. There is little difference between the two softwares in editing PDF images. Both softwares can support image addition, replacement, cropping and extraction. UPDF is outstanding in image addition and replacement, and supports direct drag and drop to add and replace images. In addition to the usual text and image processing, both support the movement and deletion of specific graphics (path elements) in documents, which is a function that many other softwares do not have. Acrobat and UPDF both support editing and adding document links by adding jumps to pages or web pages.
