Frequently asked questions
Is it safe to merge legal or tax PDFs on Utilix?
Yes. Because merging runs via client-side pdf-lib inside your browser tab, sensitive tax, medical, or legal records never leave your device.
How many PDF files can I join at the same time?
There is no artificial limit. You can combine 2, 20, or 50+ PDF files in a single pass.
Does merging PDFs degrade text sharpness?
No. Utilix copies vector page trees directly without rasterizing text, preserving 100% vector crispness.
Can I rotate upside-down scans while merging?
Yes, use the Page Rotation selector (0°, 90°, 180°, 270°) to normalize orientation during concatenation.
Do I need to create an account?
No account, email, or credit card is ever required.
