What does merging PDFs do?
Merging PDFs copies every page from each file, in the order you choose, into one new PDF. This tool does it in your browser with pdf-lib, so the documents are never sent to a server, which matters for bank statements and ID papers.
Features
- Up to 30 PDFs at a time
- Drag in files or pick them from your phone
- Reorder or remove files before merging
- Keeps every page at its original quality
- No upload, watermark or account
How to use the merge PDF
- Choose two or more PDF files.
- Put them in the order you want with the arrows.
- Press Merge, then Download PDF.
When a file will not merge
Password-protected PDFs cannot be read without the password, and some bank statements are locked this way. Open the file in your PDF reader with its password, use Print → Save as PDF to save an unlocked copy, then merge that copy.
Frequently asked questions
Are my PDFs uploaded?
No. They are read and combined in your browser. Nothing is sent to CrizaTools or anyone else.
Does merging reduce quality?
No. Pages are copied as they are, so text stays sharp and searchable.
Can I merge images and PDFs together?
Convert the images with JPG to PDF first, then merge the result with your other PDFs.
