Fast, free tools for PDFs, images, audio, QR codes & more

The ConvertHub is a browser-based platform that consolidates everyday file tools into a single, streamlined interface. It supports common workflows across PDFs, images, audio, and QR codes, allowing users to convert, compress, and create without switching between multiple websites.
Built for students, creators, and businesses, The ConvertHub emphasizes quick completion of routine tasks with a minimal user interface. Core tools require no installation or sign-up and are accessible from any modern browser on desktop or mobile devices.
Users select a tool category (PDF, image, audio, or QR) and perform the required action directly in the browser. Typical workflows include uploading files, choosing an operation (such as merge or resize), and downloading the processed output. QR code generation supports customization, including logos and dynamic tracking.
Processing runs on optimized cloud infrastructure to deliver results quickly. Files are encrypted during handling and stored temporarily. By default, files are retained for 24 hours, with an optional Pro setting that extends retention up to 30 days. Core tools can be used without creating an account.
