Can I merge PDFs without Adobe Acrobat?

Yes. This tool merges PDFs entirely in your browser with no software to install. It handles the same task as Adobe Acrobat's 'Combine Files' feature — completely free.

Is there a limit on how many PDFs I can merge?

There is no hard limit. Most devices comfortably handle 20–50 files. For very large batches (100+ files or total size over 200 MB), merge in groups for best performance.

Does merging PDFs reduce quality?

No. The merger combines the original PDF data without re-encoding images or fonts. The output maintains the exact same quality as the source files.

Can I reorder pages before merging?

Yes. Drag and drop the files into your preferred order before clicking merge. The final PDF follows the order you set.

Are my PDF files uploaded to a server?

Never. All processing happens locally in your browser using pdf-lib. Your documents stay on your device — suitable for contracts, medical records, and confidential files.

Can I merge password-protected PDFs?

If a PDF requires a password to open, you'll need to provide it first. Once unlocked, it can be merged like any other file.

What's the maximum file size supported?

Each individual file can be up to 100 MB depending on your device's memory. The combined output can be larger since it's assembled from the source pages.

Does the merged PDF preserve bookmarks and links?

Internal page links and bookmarks are preserved when possible. External hyperlinks remain functional in the merged output.
