How to Merge PDF Files Online
Merging PDF files is one of the most common document tasks — whether you're combining a cover letter with a resume, assembling a report from multiple chapters, or consolidating scanned pages into a single file. With Dockitt, you can merge as many PDFs as you need directly in your browser, without installing anything.
Step-by-step instructions
- Go to the Dockitt Merge PDF tool.
- Click 'Choose PDFs' and select all the files you want to combine. You can select multiple files at once.
- Arrange the files in the order you want them to appear in the final document.
- Click 'Merge PDF' and wait a few seconds.
- Download your merged PDF file.
Common problems
The merged PDF is missing some pages.
Make sure all files uploaded correctly before merging. If a file failed to upload, remove it and re-add it.
The page order in the merged file is wrong.
Reorder the files before clicking Merge. The final document will follow the order shown in the upload list.
One of the PDFs is password protected and won't merge.
You need to unlock the PDF first. Use the Dockitt Unlock PDF tool to remove the password, then try merging again.
The merged file is very large.
After merging, you can use the Dockitt Compress PDF tool to reduce the file size without losing quality.
FAQ
How many PDF files can I merge at once?
You can merge multiple files in one go. There is no hard limit on the number of files, but very large uploads may take longer to process.
Will the formatting and fonts be preserved after merging?
Yes. Merging PDFs does not alter the content of individual files — text, images, fonts, and layout are all preserved exactly as they are.
Can I merge a scanned PDF with a regular PDF?
Yes. Scanned PDFs and regular PDFs can be merged together without any issues. The result will be a single PDF containing all pages.
Is it safe to merge PDFs online?
Yes. Dockitt processes your files in the browser where possible, and any files sent to the server are deleted immediately after processing. We do not store or access your documents.
Can I merge PDF files on my phone?
Yes. Dockitt works on mobile browsers — you can upload, merge, and download PDFs directly from your iPhone or Android device.
