Both tools work well on combining multiple PDF documents and contain several other functions. However, there are some differences between two files.

Upload limitation: Soda PDF has limits to the file size (but the website doesn’t tell the maximum size it allows, which is not really friendly), while LightPDF has no limitation to the file size.

Supported systems: Although you can visit Soda PDF website on your mobile, when it comes to the merge page, you upload more than two files, and then you cannot find the merge button and cannot merge PDF files online.

User-friendly options: As mentioned above Soda PDF gives more options for users to upload and get their files. Also, it allows users to rearrange the files before combining.

Speed: Both tools are powerful to run, but LightPDF seems to work faster when uploading and merging files.

Interface: The two online tools have a clean and straightforward interface, so people can use it without confusion. However, Soda PDF has some ads on its sites.
