What is FastConvert?

A complete suite of image and PDF tools that run entirely in your browser.

FastConvert is a free online platform that provides a comprehensive collection of image conversion, compression, editing, and PDF manipulation tools. Unlike traditional online converters that require you to upload your files to remote servers, FastConvert processes everything locally using modern browser technologies like the HTML5 Canvas API and JavaScript libraries.

This privacy-first approach means your sensitive documents — passport photos, government ID scans, financial PDFs, personal images — never leave your device. There are no file size limits imposed by server constraints, no waiting in processing queues, and no risk of your files being stored on third-party servers.

Built for Real-World Needs

FastConvert was specifically designed to solve common, everyday problems that millions of people face. Students applying for competitive exams need to compress passport photos to exactly 20KB or 50KB. Web developers need to convert images to WebP format for better performance. iPhone users need to convert HEIC photos to JPG for compatibility. Professionals need to merge multiple PDFs into a single document for email. Our tools handle all of these scenarios and more, with a clean interface that works on any device.

Every tool on FastConvert is completely free to use — no hidden fees, no premium tiers, no watermarks, and no registration required. We believe powerful file utilities should be accessible to everyone, regardless of their budget or technical expertise.
