Choosing well
Which platforms does it need to run on?
Start with the device you plan to use. Android availability varies, so check for Android support if you want to convert files on a Xiaomi, Redmi or POCO phone or tablet.
If you plan to work elsewhere, compare support for web, Windows, Mac or Linux.
What conversion options should I compare?
Check that the tool covers the file types and conversion workflow you need. The comparison includes batch conversion, cloud conversion and OCR conversion, so look for the options relevant to your work.
For larger files or repeated jobs, check the maximum file size and whether batch conversion is available.
Can I use it on a free plan?
Compare whether a free plan is available and what it costs to move to a paid plan. Pricing models and plan details differ, so review the terms for the tool you are considering.
Do I need an API or a particular deployment option?
If you want to connect conversion to another service, compare API access. If the way software is deployed matters for your work, compare deployment options before committing.
Do I need open-source software?
If you need to inspect or change the code, check the tool’s license and whether it is open source. Pricing alone does not tell you whether the code is open.
