Before joining several PDFs, check their order, whether you can upload them, and the cost. This page helps you choose an official service for your circumstances; SiteCurio does not process the files for you.
Quick choice
Merge in a browser without registration: PDF24
About PDF24 · Its official merge tool lets you select files, rearrange them, merge them and download the result. PDF24 describes the online tool as free and available without registration. Processing occurs on its servers, and the operator says uploaded files are deleted within one hour after processing.
Work with cloud files: iLovePDF
About iLovePDF · The service says you can bring in PDFs from a device, Google Drive or Dropbox, reorder them and merge them. Limits on a free account can vary by plan and task, so confirm the current allowance before starting.
Keep the pages in the right order
- Make copies of the original files.
- Select only the PDFs to be merged.
- Check file and page order before merging.
- Download the result, then inspect the first and last pages, page count and displayed text.
Check each service’s separate rules for password-protected PDFs.
When uploading is not appropriate
For contracts or customer records that must not go to an external server, check your organization’s security policy before using an online tool. PDF24 also describes an offline merge option in PDF24 Creator for Windows. You must check whether installation is allowed and fits your policy.
