About FileConverter

FileConverter is a collection of 43 small, fast tools for everyday file jobs: converting images between JPG, PNG, WebP and iPhone HEIC, compressing photos to any KB size, resizing, combining images into a PDF, formatting and validating JSON, converting between JSON, CSV and YAML, and encoding Base64.

Why it is different

• No upload. Every tool runs inside your browser, so your files stay on your device.
• Instant. There is no waiting for an upload or a server queue; results appear in a moment.
• No sign-up. Open a tool and use it. Nothing to install or register.
• Checks your files. Each tool reads the real file type and tells you if you picked the wrong tool.
