FAQ
Everything you need to know about the Merge PDF.
Is there a limit to how many PDFs I can merge?
You can merge numerous files at once. Performance depends on your device since everything runs locally.
Are my PDF files uploaded anywhere?
No! Unlike most online tools, we process your PDFs entirely within your web browser. Your sensitive documents never touch our servers.
Does merging reduce the quality of my PDFs?
No, merging PDFs preserves the exact original quality of the pages without any compression or degradation.
Is this tool free to use?
Yes, merging PDFs is free to use with generous limits, and no annoying watermarks added to your final document.
Can I merge PDFs on my phone?
Yes, the tool is fully responsive and works directly in your mobile browser without installing any apps.
Is Refinata better than iLovePDF for merging PDFs?
Refinata offers three structural advantages: (1) Your files never leave your device — zero upload, zero server storage. (2) Page thumbnail preview runs locally — iLovePDF must upload your files before showing thumbnails. (3) No file count or size limits in the free tier. The merge quality is identical (both use PDF spec-level page copying).
Does merging create a larger file than the sum of the parts?
The merged file is typically 0–1% larger than the combined input. This minor overhead comes from the new document structure pdf-lib writes. No re-compression occurs, so quality is identical to the originals.
