Frequently Asked Questions
Is PDFStitch really free?
Yes — 100% free, forever. No premium plans, no credits, and no limits on the number or size of files you can merge.
Do I need to create an account?
No. You can merge PDFs instantly without signing up or providing any personal information.
Are my files safe and private?
Absolutely. Your PDFs are processed entirely in your browser — never uploaded to our servers or any third party. Once you close the tab, nothing is retained.
How many PDFs can I merge at once?
There is no hard limit. You can merge as many PDFs as you like. Performance depends on your device's memory, but most computers handle hundreds of files easily.
Can I reorder the files before merging?
Yes! After uploading, drag the ≡ handle next to each file to rearrange the order before clicking Merge.
What is a PDF stitcher or PDF joiner?
A PDF stitcher (also called a PDF joiner, PDF combiner, or PDF merger) takes multiple separate PDFs and combines them into one file. PDFStitch does exactly this — for free, with no watermark.
Does the merged PDF have a watermark?
No. PDFStitch never adds watermarks, logos, or any branding to your merged PDF file.
