Free browser-based file tools & test file generator
ByteRivet is a free, browser-based toolkit for working with files. Generate dummy test files at any exact size across 19 formats — PDF, PNG, ZIP, DOCX, and more — or merge, convert and edit PDFs and images. Everything runs locally in your browser, so your files are never uploaded, never stored, and the tools even work offline. Built for developers, QA engineers, and anyone who needs a quick file task done without signing up or handing their data to a server.
