Is Konnect2Tools free?

Yes. These in-browser tools are completely free to use with no account required for core functionality.

Do my files leave my device?

Browser document operations run locally, except where the operation uses an external service, such as AI summarisation. Read the processing note before using sensitive inputs.

Is the Merge PDF online tool safe to use?

Local operations process document content on your device. External-service operations may send inputs as described in the processing note. Keep originals and inspect the output.

How many PDFs can I merge at once?

The browser merger accepts up to 40 files. Available device memory can impose a lower practical limit. For a large packet, try smaller groups and inspect each intermediate result.

Does merging preserve hyperlinks and bookmarks?

Do not rely on bookmarks, hyperlinks or interactive features being preserved when pages are copied into a new document. Test any links you need in the downloaded file. Keep the originals for their original navigation, form behavior and signature verification.

Can I reorder pages from different PDFs during the merge?

Yes — you can reorder entire files before merging by dragging them. For page-level reordering within a merged result, use the Organize PDF Pages tool after merging.

Will the merged PDF be larger than the sum of the individual files?

Typically, yes — very slightly larger due to the merged file header and cross-reference table. If size is a concern, compress the merged result using the Compress PDF tool.

Merging multiple PDF files into a single document is a daily task for students, professionals, and businesses. Whether you are combining chapters of a report, joining scanned invoices for an accountant, or bundling a cover letter with your resume before applying for a job, having a fast, reliable merge tool saves significant time compared to re-printing and scanning.

Select multiple PDFs and check their order before combining them into one downloadable file. This operation runs in your browser and copies pages into a new document. Inspect the output: bookmarks, interactive fields, attachments, accessibility tags and digital signatures are not guaranteed to survive page copying. Keep the originals, especially when signature verification matters.

Unlike desktop PDF software that requires installation and a licence, this online merger works on any device with a modern browser — including Android and iOS phones. Students assembling application packets, HR teams building onboarding kits, and freelancers combining project deliverables can use it without installing anything.

Tips for best results

1Check the selected file order before merging. If it is incorrect, use the available order controls or remove the files and select them again.
2If your output file is too large, run it through the Compress PDF tool immediately after merging.
3Check that all input PDFs are not password-protected; remove passwords first using the Remove PDF Password tool.
4For scanned documents with mixed orientations (portrait and landscape), use the Rotate PDF tool on individual files before merging.
5Merged PDFs inherit the page sizes of the source files — if you need a uniform page size, use the Resize PDF tool after merging.
