Frequently Asked Questions

When should I split by size instead of compressing?
Use size-based splitting when a portal has a hard cap and you want to preserve quality. Compression may reduce fidelity, while splitting keeps each section closer to the original.
Can I choose the maximum size per file?
Yes. This workflow is meant for exact upload scenarios where each output file must stay under a known limit.
What kinds of workflows need this most?
Government submissions, legal filings, procurement portals, and email attachments are the most common size-sensitive use cases.
