Frequently asked questions
- Can I convert a PDF to MP4 for free?
- Online-Convert offers free trial credits that renew every 24 hours, with paid credit plans for heavier use. Vidsembly's free tool creates up to 3 narrated projects a day with a watermark and no account, and the app includes 30 free credits to try the program.
- Does Online-Convert add narration to a PDF video?
- Its PDF to MP4 page lists codec, audio quality, and cut-video options, and does not mention narration or AI voices. Try a sample file to see what the output looks like. Vidsembly adds an AI voiceover as a core part of the process.
- What is the difference between a PDF to MP4 converter and PDF to video with narration?

- How is Online-Convert priced?
