Bubbles helps you master German, French, Kannada and/or Hindi through puzzles and tutorials. It helps you gain a deeper understanding of the vocabulary and grammar of your chosen language.

I built PdfCombine because I got tired of tools that ask you to upload sensitive documents on their server or limit how many PDFs you can merge. So here’s a simple solution that is completely free and works directly in your browser!

Hey! I built PdfCombine to solve a simple problem: merging PDFs shouldn't be complicated, paid or risky. So I made my own tool - everything runs right in your browser so no uploads, no worrying about where your files go. It’s fast, totally free, and super easy to use. You can upload files one by one, reorder them however you like and download the final PDF in seconds. No limits, no signup, just a clean little tool that does one thing well. Hope it saves your time!
