FAQ
Common questions
Do I need to register to convert files?
No. You can use the service without an account, but free registration increases daily limits.
How long is the result stored?
Guest conversion results are available for 1 hour. After that, files are cleaned up automatically.
How do I know the file is ready?
After starting conversion, the service shows the processing status. When the job is complete, you will move to the result page and download the file.
Can I process multiple files at once?
Merge PDF supports multiple files with ordering. Other tools process one file per job to keep the result predictable.
