How to choose
Which file types does it support?
Choose a converter that lists the input and output formats your work requires. Compare supported file types directly rather than assuming a general-purpose tool handles a particular format.
Check whether output-quality controls are listed when visual or audio fidelity matters.
Which platforms does it need to run on?
Pick a tool that matches your devices: Windows, macOS, web, Linux or Android are listed platform options.
An API option can suit a workflow that sends conversions from another app or service.
Do you need offline conversion?
Choose a tool that lists offline conversion when files must be processed without sending them to a web service.
For browser-based tools, check maximum file size and the supported platform before relying on them for large files.
Can it convert batches of files?
Use the batch-conversion field to find software that can process groups of files in one job.
For larger or more demanding jobs, consider the listed file-size ceiling and whether quality settings are available.
What will the converter cost?
A free plan is listed for tools such as Aconvert, AnyConv, Convertio and Converseen. AVS Document Converter shows an annual price of $149; CPC Tool provides no set price in the listing.
dBpoweramp Music Converter offers a 21-day trial and no free plan. Check whether the plan or trial covers the formats and limits you need.
