About the Merge PDF
Tezmy's Merge PDF tool joins several PDF files into a single document in the order you choose. Unlike most online PDF mergers, your files are never uploaded to a server: the merging happens right inside your browser, which makes it faster and keeps private documents like contracts, invoices and bank statements on your device. There are no file limits, no watermarks and no sign-up.

When do you need to merge PDF files?
Many websites and offices ask for a single PDF, even when your documents come in several files. Common examples:
- Job applications: your CV, cover letter and certificates in one file.
- Visa, passport and university applications that allow only one upload.
- Invoices, receipts or bank statements for your accountant.
- Pages you scanned one by one with your phone.
- School or college assignments made of several parts.
How to get the order right
Files are joined from top to bottom, in the order shown in the list. Use the up and down arrows to move a file, and check the page count next to each one so you know nothing is missing.
Tip: if you merge the same kind of documents often, name them 01, 02, 03 before adding them. To change the order of pages inside one PDF, split it first with Split PDF, then merge the parts in the order you want. Unwanted pages can be removed afterwards with Delete PDF Pages.
Merge PDFs on iPhone, Android or computer
There is no app to install. On an iPhone or iPad, open this page in Safari, tap Select PDF files and choose several files at once from the Files app. On Android, pick them from your Downloads or Google Drive. On a computer you can also drag the files straight onto the page. The merged PDF is saved to your downloads folder.
Merged file too big to upload?
Combining scanned documents can make a large file. Open the merged PDF in our Compress PDF tool and choose Recommended: scanned pages usually become several times smaller while staying easy to read.

Frequently asked questions
Is it safe to merge private PDFs here?
Yes. Your PDFs are processed entirely in your browser and are never uploaded to our servers, so nobody else can see them.
Is there a limit on how many files I can merge?
There is no fixed limit. Very large files depend on your device's memory, but most computers and phones handle dozens of normal PDFs easily.
Can I change the order of the pages?
You can change the order of the files with the up and down arrows. Pages inside each file keep their original order.
Why can't a PDF be merged?
Password-protected PDFs can't be read until they are unlocked. Damaged files or files that aren't really PDFs will also show an error.
Will the merged PDF have a watermark?
No. Tezmy Tools never adds watermarks. Your merged file looks exactly like your originals.
Can I merge PDFs on my phone?
Yes. The tool works in Safari, Chrome and other mobile browsers. Select several PDFs at once from your Files app or Downloads, put them in order and tap Merge PDFs.
Can I merge a password-protected PDF?
Not directly. Protected PDFs can't be read until they are unlocked, so remove the password first (for example by opening it and saving a copy without a password), then merge.
Does merging reduce the quality of my PDFs?
No. Pages are copied exactly as they are, so text stays sharp and selectable and images keep their original quality.
