Merging is a weekly task — and a privacy risk
Combine your application letter and CV. Attach your bank statement to a form. Bundle three invoices for your accountant. Every one of those "merge PDF" searches hands your documents to a website — and most websites mean your files are uploaded to a server you know nothing about.
For a menu you downloaded, that is fine. For documents with your account numbers, address or national ID on them, it should not be fine.
What "client-side" actually means
KiaKia Tools merge runs on WebAssembly inside your browser. In plain language: the website delivers the tool to your device, and your device does the work. The files are read from your disk into the browser's memory, combined, and saved straight back — no network upload happens at any step.
You can even prove it to yourself: open your browser's developer tools, watch the Network tab while you merge, and notice that nothing but the website's own files is transferred.
How to merge properly
- Open Merge PDF and select your files
- Drag them into the exact order you want
- Merge and download the combined document
Need to remove a page first, or fix the page order? Reorder & Delete PDF Pages handles that. Need the result smaller? Compress PDF finishes the job.
A short privacy habit worth building
Before you combine or convert anything sensitive, ask one question: does this tool need my file on its server to do the job? The honest answer for merging, splitting, signing and converting is no — all of it can be done locally, and all of it can be done on KiaKia Tools without your documents ever leaving your hands.
Your paperwork is your business. Literally.
