klzth is a lightweight PDF merging tool built for people who want to get the job done without handing their documents to a third-party server.

Select your PDF files, arrange them in the right order, and merge them directly from your browser. Your documents stay on your device during the process, making the tool especially useful for files that contain personal or business information.

The merger works with the existing PDF pages instead of rebuilding them from scratch, helping preserve text quality, images, and document structure. Different page sizes can also be normalized to A4 when needed, while filenames can be used to quickly organize larger batches of files.

There is nothing to install and no account to create. No subscription is required, and merged PDFs come without watermarks.

Free users get 3 merges per month. For occasional heavier use, klzth offers simple one-time options: $5.50 for 30 merges or $9.90 for 100 merges.

Simple PDF merging, processed in your browser and paid for only when you need more.website:https://www.klzth.com/
