Merge PDF Files into One Document
ReadyCombine multiple PDFs into a single file. Arrange reports and attachments, join the PDFs in your browser and download the result without uploading the files.
All tools are free to use. File size and processing limits may vary by tool.
How to use Merge PDF
Select the files, set the order with the arrow buttons, then run. Ideal for gathering a report and its attachments. Download and verify the page count.
Browser tools keep files on your device. Advanced document tools upload files for temporary server processing; the tool shows this before upload. Web lookups send queries to the server and public lookup services.
Merging PDF files in the right order
Merging collects separate PDF documents into one file, page after page. It is useful for rental applications, school enrolment or visa paperwork where scattered attachments should become a single package. Existing pages are kept as they are; documents are not overlaid onto one page. Mixed paper sizes can coexist in the output, so merging does not equalise page dimensions. Ordering mistakes are the most common error: the cover letter goes first, supporting documents follow, and you note the starting page of each part.

Send the completed PDF to compression, page extraction, rotation, watermarking or numbering without selecting it again. Filled forms can also go to flattening. You start each step; modifying a document may affect digital signatures. Split-result ZIP files are not transferred.
Transfer happens between open tabs; we do not save the file in browser storage for this. This step does not start a new upload. Choosing server processing in the destination uploads the file again; its size limit applies.
