#1 Sejda Online

Sejda Online is a web-based PDF editing and manipulation tool. It offers numerous features and functionalities that allow users to work with PDF files directly in their web browser without installing software. Additionally, it is compatible with various OS and can be accessed using any device. 

However, despite offering a vast array of features, Sejda Online suffers from drawbacks like slow application of modifications when handling larger PDFs. Moreover, the platform imposes limits on file sizes up to 50 MB for free usage, potentially hampering efficiency for users who frequently deal with bigger files.

#2 Sejda Desktop

The core of Sejda Desktop is also hosted on the website's end, which makes it difficult for them to bring the exact functionality of the Desktop version into it. Despite offering similar functionality to its web-based variant, it doesn't possess mobile applications. With Sejda Desktop, users can read, modify, mark up, and manage PDF documents just like they would on the website.
