Answers to the questions we get most.
Frequently asked questions
Where do my files go when I use a tool?
Nowhere. The file is read by JavaScript in this tab and the result is written back to your device. There is no upload.
A tool failed on my file. What now?
Most failures come from a damaged or already-encrypted PDF. Try opening it in a reader first. If it opens but the tool still fails, email support with the tool name and browser.
Is there a file size limit?
No fixed limit. Very large files are limited by your device memory, and a phone will give up sooner than a laptop.
Can I use the tools offline?
Once the page has loaded, most tools keep working without a connection. OCR needs one connection to fetch its language model, then caches it.
How do I remove a password from a PDF?
Open it in a reader with the password, then print or export to a new PDF. Scanix will not strip protection from a file, since we cannot tell whether it is yours.
Do you support batch processing?
Merge, image to PDF and split all accept multiple files or produce multiple outputs. Others handle one file at a time.
