PDF Merger — Frequently Asked Questions
How do I merge PDFs online for free?
Drop your PDFs into the merger, drag them into the order you want, and click Merge. The combined PDF downloads instantly — no sign-up, no watermark.
Is there a file-size or page limit?
No hard limit. Because merging happens in your browser, the practical ceiling is your device’s memory — typically several hundred MB of PDFs combined.
Will the merged PDF keep bookmarks and links?
Yes. Internal links, outlines and metadata from each source PDF are preserved in the output wherever the source file exposes them.
Is it safe to merge confidential PDFs here?
Yes — nothing leaves your device. TinyPDFs runs the merge locally, so sensitive documents never touch our servers.
