Frequently asked questions
Is it free to merge PDF files?
Yes. Merging PDFs on PDF FixKit is free and requires no account. Daily limits apply to keep the service fast for everyone.
What happens to my files after merging?
Your files are processed on our servers and deleted automatically within 2 hours. We never read, share, or keep your documents.
In what order are my PDFs combined?
Files are merged in the order you add them — the first file you select becomes the first pages of the merged document.
Is there a file size limit?
Free merges accept files up to 80 MB each and up to 3 files per merge. Larger limits are coming with PDF FixKit accounts.
Does merging change the quality of my PDFs?
No. Pages are copied into the new document exactly as they are — no re-compression, no quality loss.
