How to choose
Which file formats does it need to open?
Start with the formats you use, then compare the supported-formats details for each tool.
A reader that does not support a file you need may not fit, even if it runs on your preferred device.
Which platforms does it need to run on?
Choose software that supports the platforms where you plan to read: Windows, macOS, Linux, Android, web, or iOS.
Check platform support before choosing, especially if you switch between a computer, phone, or browser.
Do I need search, annotations, or accessibility support?
Compare text search, annotations, and accessibility support against the way you read.
These are separate comparison fields, so check the details for the feature you need rather than assuming it is included.
How can I compare free plans and paid options?
Check whether a free plan is available, what the paid price starts at, and whether a free trial is offered.
For example, Apple Books Digital Narration and Foxit PDF Reader are listed with free plans; File Viewer Plus has a 14-day trial.
Will my reading carry across devices?
Check the cloud-sync details if you want reading to connect across devices.
Also confirm that the software supports the platforms you use; cloud sync and platform support are separate comparison points.
Questions

Can I get file reader software for free?
Check the free-plan field. Some listed tools have a free plan; pricing details can also show paid options or a free trial.

It is a score out of 10 based on maker-published information about use, a public API, documentation, open-source code, and a free tier.
