Merge PDF
Combine multiple PDF and supported image files in one workspace. Preview, reorder and organize pages before creating your final PDF.
PRACTICAL WORKFLOW NOTES
Check the Whole Document Before You Merge It
Merging is most useful when the final document is treated as one finished file rather than a stack of sources that happen to be joined together. A contract, application, report, scan set, or project pack can include pages from different PDFs as well as supporting images, and the order often matters as much as the merge itself. The current Merge PDF workspace lets you combine PDF, JPG, PNG, WebP, and TIFF content, inspect what was added, and correct the sequence before creating the output. That means a sideways scan, an extra attachment, a missing separator page, or a page that belongs earlier in the document can be fixed before download instead of after the mistake has already been shared.
The easiest way to avoid rework is to make the important choices before creating the final file. Start with the files that belong in the final document, then add anything you notice is missing without clearing the current workspace. Use page cards for a quick check and open the larger preview when similar scans or attachments are difficult to identify from a thumbnail. Then check the sequence or settings once more before processing the full job.
A few controls make the biggest difference in Merge PDF. Rotate pages that arrived sideways, duplicate content that must appear twice, and delete material that should not be included. Insert a real A4 portrait blank page when a section needs a separator or an intentional empty page. Keep the source file until the result has been opened and checked, especially when the output is going to a client, a form, an archive, or another production step.
The current merge operation is built in the browser rather than by sending the selected document contents to a remote merge queue. Browser memory and device performance can still matter for larger jobs. If the next task is different, Compress PDF is available when you need to reduce the size of the finished document when it is too large for email, upload, or sharing. Keeping the next step separate makes it easier to tell which operation changed the document and to return to the untouched source if a different result is needed.
How to Merge PDF Files
The workflow stays simple while leaving room to correct the document before it is finished.
Add your documents
Select one or more PDFs or supported image files. Add more files later without clearing the work already in the workspace.
Check what you added
Use the page cards for a quick check or open the large preview when you need to inspect a scan, attachment, or document more closely.
Set the page order
Drag pages or items into place, move them directly to a chosen position, or use filename sorting when the source files are already numbered in sequence.
Fix the details
Rotate a page, duplicate content that needs to appear again, remove what you do not need, or place a blank page between document sections.
Create and review the PDF
Choose the output name, merge the document, then use the result preview to make sure the finished file is the one you intended to create.
Control the Document Before the Final Merge
The useful part is not just combining files. It is being able to prepare the document without moving between several separate tools.
Drag or move to an exact position
Drag for quick changes, or choose the destination position when moving something across a longer document.
Large preview with controls
Open the document at a larger size to verify the content and continue supported page actions without relying only on small thumbnails.
Rotate, duplicate, and delete
Correct sideways pages, reuse content that should appear twice, and remove a wrong page or file without restarting the merge job.
Insert a real blank page
Add an A4 portrait blank page between sections and move it like the other items. It becomes an actual page in the finished PDF.
Add more files as you work
Bring another document into the current workspace when you notice something is missing instead of rebuilding the job from the beginning.
Filename sorting and output naming
Keep your manual order or sort numbered source files by name, then give the final PDF a useful filename before it is created.
Combine PDF Files and Images in the Same Job
You do not have to convert every supporting image into a separate PDF first.
PDF documents
Existing PDF pages are copied into the combined document rather than intentionally flattened into screenshots just to join the files.
JPG, PNG, and WebP
Photos, scans, screenshots, and other supported images can become pages in the same final PDF alongside the original PDF documents.
Single-page and multi-page TIFF
The merge workflow can read TIFF input, including readable frames from a multi-page TIFF, and include them in the combined document.
Larger document sets
There is no fixed page or file-count limit in the current workflow. Larger jobs can take longer depending on browser memory and device performance.
Keep Working After the Merge
The merged PDF can be the end of the job, or the starting point for the next one.
Add Page Numbers
Number the finished document after the page order has been finalized.
Compress PDF
Reduce the file size when the combined document is too large for sharing or uploading.
PRIVACY & RESPONSIBLE USE
A Short Note About Your Files
The current Merge PDF workflow processes the selected document contents in your browser and does not create a server-side document copy for the merge operation. Files remain available to the active workspace while you are working, and reloading or closing the page clears that browser session.
See File Security & Processing and the Privacy Policy for the broader site-level details.
No remote merge queue
The merge itself is built in the browser rather than by sending the selected document contents to a remote conversion queue.
Use files you may lawfully process
Only combine documents you created, own, are licensed to use, have permission to process, or may otherwise use lawfully.
Merging does not change copyright
Combining, copying, or rearranging pages does not transfer ownership or remove an existing license, attribution duty, or other right.
Copyright: The tool does not grant permission to use third-party material or bypass passwords, encryption, DRM, or document restrictions. See the Copyright & Intellectual Property page for the full site notice.
COMMON QUESTIONS
Frequently Asked Questions About Merging PDFs
Can I merge PDF files online for free?
Yes. The current Merge PDF tool is free to use and does not require an account. Add your files, organize the document, and create the combined PDF in the same browser workspace.
Can I combine more than two PDF files?
Yes. The workflow is designed for multiple files and has no fixed page or file-count limit. Larger jobs may take longer depending on browser memory and device performance.
Can I change the page order before merging PDFs?
Yes. Reorder pages or items by dragging them, move them to an exact position, or use filename sorting when the source files are already named in sequence.
Can I rotate, delete, or duplicate pages before merging?
Yes. You can correct page orientation, remove unwanted content, duplicate content that needs to appear more than once, and keep organizing the document before the final PDF is created.
Can I combine PDF and image files together?
Yes. PDF, JPG, JPEG, PNG, WebP, TIF, and TIFF files can be used in the same merge job. Images become PDF pages, and readable frames of a multi-page TIFF can be included.
Can I add a blank page between PDF documents?
Yes. Insert a blank A4 portrait page, place it where you need it, and it becomes a real page in the finished PDF.
Are my files uploaded to a server for merging?
The current Merge PDF workflow processes the selected document contents in your browser and does not create a server-side document copy for the merge operation.
What can I do after merging the PDF?
From the result workflow you can continue with related PDF Core Tools for page numbering or PDF compression.
