Frequently Asked Questions
More on quality loss: conversion quality guides · compression guides
Is PDF merge free?
Yes. Unlimited merges in your browser with Format Convertly — no watermark.
Do you store my PDFs?
No. Merging runs locally. Nothing is uploaded to a server queue.
Can I reorder files before merging?
Yes. Arrange the list so pages appear in the order you need.
Need pages from one PDF only?
Use Split PDF to extract a range or burst every page into its own file.
Does converting or exporting a PDF reduce quality?
Rasterizing pages or re-encoding embedded images can. Keep vector text when possible and avoid unnecessary re-exports of scanned pages.
