What it does

Combine separate PDFs into one document for a single upload or handover. The pages stay together in the order you choose, so a reader can follow the whole bundle without opening several attachments.

How to use it

  1. Upload PDFs

    Select or drop at least two PDF files. The tool validates file type, per-file size, and total count before merging.

  2. Arrange the order

    Preview filenames in the right panel and reorder files by dragging rows or using the up and down controls.

  3. Merge and download

    Run the merge for 1 credit, then download the single merged PDF or retrieve it later from recent history.

Benefits

Why use Merge PDFs?

Practical advantages built around real creation, selling, and operations workflows.

Simple multi-file merging

Upload several PDFs, preview their filenames, reorder them, and export one combined document.

Order control

Drag files into sequence or use arrow controls so cover pages, attachments, and appendices land exactly where they belong.

PDF-only validation

Friendly checks keep the workflow focused on supported PDF files with practical file count and size limits.

Temporary upload handling

Uploaded source PDFs are read only for processing and are not retained as permanent input files.

Works in your browser — nothing to install

Upload, process and download from your device without installing desktop software or plugins. Check the tool above for sign-in requirements before starting.

Download recent results again

Signed-in users can find recent successful results in History. Save your own copy after processing so you have it when you need it.

Merge PDFs questions

Answers to common questions before you run the tool.

How many credits does Merge PDFs use?

Merge PDFs uses 1 credit per successful merged PDF.

Which files can I upload?

The tool accepts PDF files only, with a limit of 12 files and 25MB per file.

Can I change the merge order?

Is my file kept after processing?

Your upload is used to complete the requested task. Finished files can be downloaded from recent History when you are signed in. There is currently no fixed automatic deletion period for saved results; contact support@azanai.cloud to request deletion. Download a local copy rather than relying on History as your only backup.

Where does the merged file appear?

After a successful run, the merged PDF is available from the result download link and recent history for signed-in users.

Will encrypted PDFs work?

Password-protected or encrypted PDFs may fail to merge. Remove passwords before uploading those files.

A free account starts with monthly credits. Tool access and any available guest trial are shown above; some tools require sign-in or a paid plan. Check the displayed cost before starting. Failed tasks are refunded, and paid plans include non-image tasks under fair use.
