Frequently Asked Questions

Can I merge password-protected PDF files?

Our tool currently supports merging of standard, unprotected PDF files. If your documents are password-protected, you'll need to remove the protection before merging them.

Is there a limit to how many files I can merge at once?

PDFMerge Pro allows you to merge up to 20 files simultaneously, which should accommodate most merging needs. For larger projects, consider breaking them into multiple merging sessions.

Will merging affect the quality of my original PDF files?

No, the merging process preserves the original quality of your documents. Our tool maintains the resolution of images and clarity of text throughout the process.

Can I rearrange pages after merging?

While our tool allows extensive rearrangement before merging, once the process is complete, you would need to use a PDF editor to rearrange pages in the final document. We recommend carefully reviewing the page order using our preview feature before finalizing the merge.

Is there a file size limit for PDFs I can merge?

Our tool offers generous file size allowances that accommodate most document merging needs. While extremely large files may take longer to process, our optimized algorithms ensure efficient merging regardless of file size.

Can I use this tool on mobile devices?

Yes, PDFMerge Pro is fully responsive and works seamlessly on mobile devices, tablets, and desktops. The interface adapts to your screen size for optimal usability across all devices.
