PDF and image tools that run over an encrypted HTTPS connection. Files are auto-deleted after processing and never stored or shared.

Merge PDF joins several PDFs, and images too, into a single file in the order you choose. An office manager uses it to put a month of supplier invoices into one document for the accountant, and a job applicant uses it to send a CV, cover letter and certificates as one attachment.

How to merge PDF files

Add your files from your device, Google Drive, Dropbox or OneDrive, up to 260 MB each. Every file appears as a card with a thumbnail. Drag the cards into the order you want, or switch to the Pages view to move single pages between documents. When the order looks right, press Merge PDF, then download the result, rename it, or send it on WhatsApp.

When to use Merge PDF

Any time several files belong together: a tenancy agreement with its inventory and deposit receipt, a tender with its drawings, a quarterly report built from three departments' sections. The reader gets one file to open and nothing goes missing in a long email thread.

You can drop JPG or PNG images in with the PDFs, so a photographed signature page or a scanned ID can sit in the right place inside the merged document.

Arranging pages before you merge

The Files view moves whole documents. The Pages view shows every page, so you can pull one out of the middle of a file and put it somewhere else. Each card has buttons to preview, rotate or remove it, and you can select several cards to move or rotate them together.

Use the insert button between two cards to add another file or a blank page at that point, handy as a separator before an appendix. Sorting by name, A to Z or Z to A, puts numbered files like invoice-01 and invoice-02 in order in one click, and Undo takes back a wrong move.

Tips for a clean merged PDF

Put a cover letter or index first and appendices last. If your files use different page sizes, say an A4 report and a US Letter scan, each page keeps its own size in the merged file, which prints without trouble.

A merged file built from scans can be large. Use Continue with this file and choose Compress PDF to shrink it before emailing. If you only need a few pages from a long document, pull them out with Extract Pages first and merge just those.

Frequently asked questions

How many files can I merge?
You can add several PDFs and images at once, each up to 260 MB. For very large bundles, merging in two or three stages keeps the thumbnails quick to work with.
Can I reorder pages while I merge PDF files?
Yes. Switch to the Pages view and drag individual pages anywhere, including between different source files.
Can I rotate or delete pages in Merge PDF?
Yes. Each card has a rotate button and a remove button, and the toolbar rotates or removes a whole selection at once.
Can I add a blank page?
Yes. Use the insert button between two cards and choose Insert a blank page. It is a quick way to keep double-sided printing lined up.
Can I merge images with PDFs?
Yes. JPG and PNG files can be added alongside PDFs, and each one becomes a page in the merged file.
Does Merge PDF change how my pages look?
It puts the pages into one file in the order you set. Apart from any rotation you apply, each page goes in as it was.
What is the merged file called?
It is saved as merged.pdf. Click the name on the result screen to rename it, for example to Invoices-March.pdf, before downloading.
