Choosing well
Check Android and other platforms
If you plan to convert files on a Xiaomi, Redmi or POCO phone or tablet, confirm that the product has an Android app. A web converter can work through a browser, while Windows, macOS and Linux apps suit desktop use. An API is useful for software workflows.
Match formats and file limits
Check the supported input and output file types against the files you handle. Maximum file size matters when converting large media or documents, so compare that limit before choosing a tool.
Look for batch and quality controls
Batch conversion can help when you have several files to process. Review the available output quality controls when resolution, bitrate or document fidelity matters.
Compare offline use and pricing
Offline conversion can be useful when files should stay on your device or when an internet connection is unavailable. Check whether the product supports offline work or requires a web connection.
Compare free plans, free trials and the paid-from price. If you need to inspect or change the code, check the open-source licence and terms.
