FAQ
PDF tool questions
Are files uploaded to a server?
No. PDFs and images are processed only in this browser.
Can I use these tools on a phone?
Yes, but large PDFs are limited by mobile memory. Use smaller batches and keep the page open.
Are password-protected PDFs supported?
Not yet. Remove the password in trusted PDF software first; never enter a PDF password into BossTools.
Are completed files saved?
No. Files and history are removed after refreshing, leaving, deleting or resetting.
Why is PDF-to-image limited to 100 pages?
It is a browser safety limit that avoids rendering too many pages into device memory at once.
Will PDF page order change?
Merging and extraction follow the displayed file order and selected page numbers exactly.
