About Me
klzth helps you turn multiple PDF files into one organized document, right from your browser.
Add the files you need, rearrange them with ease, and merge them without installing an app or creating an account. Because processing takes place locally in your browser, your documents can stay on your device instead of being sent to an online service.
The tool supports filename sorting, flexible file ordering, and optional A4 sizing for PDFs with mixed page dimensions. The original PDF content is kept intact during the merge, helping preserve text quality and embedded images.
Use klzth 3 times per month for free, or purchase extra usage whenever necessary. One-time plans include 30 merges for $5.50 and 100 merges for $9.90. There are no subscriptions and no watermarks.
A practical PDF merger for people who value simplicity, privacy, and control.
