Frequently Asked Questions

Have questions? Here are the answers about PDF Merge

How many PDFs can I merge at once?

You can merge multiple PDF files in a single operation. Our tool handles small documents as well as larger batches efficiently. For optimal performance, we recommend merging up to 20 files at a time.

Is my data secure when merging PDFs?

Absolutely! All PDF processing happens locally in your browser. Your files are never uploaded to our servers or stored anywhere. Once you close the page, all data is automatically deleted from your device's memory.

What is the maximum file size I can merge?

There's no strict file size limit, but very large files (over 100MB each) may take longer to process depending on your device's capabilities. The merged PDF size will be approximately the sum of all input files.

Can I reorder PDFs before merging?

Yes! Simply drag and drop the PDF files in the list to rearrange their order. The files will be merged in the exact order they appear in your list from top to bottom.

What does the compress option do?

The compress option reduces the file size of your merged PDF by optimizing images and removing redundant data. This is useful if you need to email the PDF or have limited storage space.

Will merging preserve my PDF metadata?

By default, yes! The 'Preserve Metadata' option keeps information like author, title, creation date, and keywords from your original PDFs. You can disable this option if you prefer a clean merged document.

Can I merge password-protected PDFs?

Currently, password-protected PDFs cannot be merged. You'll need to remove the password protection first, then merge the files. This is a security measure to ensure you have proper access to all documents.

Is there a cost to use PDF Merge?

PDF Merge is free to use! Free users get 5 merges per day with files up to 5MB each. For more daily operations and larger files, you can upgrade to Plus, Pro, or Ultimate plans.
