Frequently Asked Questions

How many PDFs can I merge for free?
SeerKits supports merging up to 10 PDF files per job on the free web tier, with each file up to 50 MB. No account is required.
Will merging reduce PDF quality?
No. SeerKits merges pages without re-rasterizing text and vectors, so print quality stays intact unless you compress afterward.
Can I insert a cover page from an image?
Convert the image with Image to PDF first, then merge it at the top of your stack in PDF Merger.
Are merged documents stored on a server?
Local merge keeps files in browser memory only. Nothing is saved after you download the combined PDF.
