Recast vs online converters: choose where files are processed

Three processing models

A native local app: Recast runs conversion on your Mac and supports batch work and a Shortcuts action. The Direct release costs $10 once and requires macOS 14 or later on Intel or Apple silicon. Practical limits still depend on formats, memory and storage.

A server-based converter: your file is sent to a service for processing. Check the particular service's retention, access, limits and suitability for the data you are authorised to send.

A browser-local converter: some tools process files in the browser. Check the specific implementation rather than assuming that every web page uploads the input or that every “local” label proves it does not.

Choose around a real output requirement

For an occasional non-sensitive conversion, an existing export function or a suitable web tool may be sufficient. For recurring batches and a local workflow, consider Recast after confirming the exact format pair. Do not buy on format totals alone.

A confidential file is not a suitable experiment for an unfamiliar upload service. Use a disposable sample to establish output quality and data handling first. No comparison on this page certifies a third-party service's security.

Use the same acceptance checklist

• Can the destination app open the entire output?
• Are required text, transparency, metadata, channels or subtitles retained?
• Can you repeat the settings and inspect failures across a batch?
• Are the original files preserved and the output location clear?
