Feature Comparison

In this section, we will provide a detailed feature comparison between PDFTron SDK and ComPDFKit SDK, focusing on their capabilities in various aspects of PDF handling. Here is a comparison of some key features:

While both SDKs provide PDF navigation, outlines, bookmarks, text search, selection, zooming, and text reflow, there are some differences in their features.

Regarding annotations, both SDKs support various types such as highlight, markup, note, shapes, and more. However, PDFTron offers a wider variety of over 30 annotation types compared to ComPDFKit's 10+ types. Both SDKs also support custom annotations, import/export of annotations, and annotation flattening. It's worth noting that ComPDFKit supports "predefined annotations" while PDFTron does not mention it.

• In terms of forms, both SDKs support filling, creating, editing, and deleting form fields, as well as flattening forms.
• For signatures, both SDKs support e-signatures and digital signatures.
• When it comes to page manipulation, both SDKs provide operations such as merging, splitting, inserting, extracting, and deleting pages.
• In terms of content editing, both SDKs support text and image editing. ComPDFKit specifically supports the "replace all" function in the "Find and Replace" feature, whereas PDFTron does not mention it.

Both SDKs also support content searching and redaction, PDF encryption/decryption, and applying watermarks. However, PDFTron does not mention support for bates numbers, header & footer.

In terms of data extraction, both SDKs allow for extracting text, images, and tables from PDFs.

Both SDKs offer conversion capabilities, including converting PDFs to/from Office formats (Word, Excel, PPT), HTML, and images. However, ComPDFKit supports additional conversions to and from CSV, TXT, and RTF, while PDFTron does not. On the other hand, PDFTron supports CAD to PDF conversion, which ComPDFKit does not.

Lastly, both SDKs support overlay comparison, content comparison, and optical character recognition (OCR).

In conclusion, while both PDFTron and ComPDFKit excel in various aspects of PDF handling, the choice between them will ultimately depend on the specific needs and priorities of the user or organization. Each SDK brings unique features to the table, and a thorough evaluation is crucial to determine the best fit for the intended use case.
