Pro Tips

Easy Reordering

In merge mode, you can easily change the merge order by dragging and dropping the file list with your mouse.

Range Specification Tips

In split mode, entering comma-separated values like '1-3, 5, 7' will divide and download them as 3 separate PDF files.

100% Privacy Protection

All PDF merging and splitting processes occur entirely within your browser. You can rest assured as no documents are sent to external servers.

Large File Handling Precaution

Since this uses browser capabilities rather than server processing, merging files over 50MB may slow down your browser depending on your environment.

Frequently Asked Questions

Are the split results downloaded as a compressed ZIP file?

No. For browser processing speed and stability, each comma-separated range is sequentially downloaded as an individual PDF file.

Can I merge or split password-protected PDFs?

Currently, secured (password-protected) PDFs cannot be edited or split directly in the browser. Please remove the password before use.

Is it safe to upload important company documents?

Yes, it is very safe. DDTool's PDF tools do not send files to a server, performing conversions entirely within the visitor's PC/smartphone browser.

Can an error occur if the file size is too large?

Due to memory limits allocated to browsers (Chrome, Safari, etc.), dealing with very large or complex files (over 50MB) may cause the browser to temporarily freeze or crash.
