What counts as an operation?
An operation is one completed use of a tool, such as merging a set of PDFs, compressing one PDF, or resizing one image. Browsing tools, selecting files, changing settings, validation errors, and failed processing do not use an operation.

- 2Review the list because files are merged in that order.
- 3Create and download the combined PDF.
How it works
Merging PDF files is one of the most common document tasks. Whether you are assembling a report from multiple sections, combining scanned pages, or joining contract appendices, having all the content in one file makes sharing and archiving far easier.
ToolPDFs reads and combines the files in this browser. Document contents are not sent to ToolPDFs application APIs. Add two or more PDFs, review the list order, and create the combined file. Password protected, damaged, or unsupported PDFs may fail to load.
Free usage requires no account and accepts files up to 25 MB each. Practical file size also depends on available memory in the current browser and device.
Features
- Combines two or more readable PDF files in the listed order.
- Remove and add files again when the list order needs to change.
- Processes PDF contents in the browser without sending them to ToolPDFs application APIs.
- All tools are included on Free with 20 total operations per day shared across all tools. The allowance resets daily, and no account or card is required. Files can be up to 25 MB.
Frequently asked questions
Are my PDF files uploaded to a server?
No. The merge handler reads and combines the PDF contents in this browser. It does not send document contents to ToolPDFs application APIs.
Is there a limit to how many PDFs I can merge?
Free files can be up to 25 MB each. Pro removes the file size limit. You can combine multiple PDFs in one merge on either plan.
Can I change the order of the PDFs before merging?
Yes. Files are merged in the order they appear in the list. Remove a file and re-add it to change its position.
What can prevent a merge?
A password protected, damaged, unsupported, or very large PDF can fail to load. Available device memory also limits practical file size.
