About SmartPic Converter

SmartPic Converter is a small, focused tool for one job: converting images between common formats — PNG, JPG, WebP, BMP, and HEIC — quickly and privately.

How it works

Everything runs in your browser using the HTML canvas API. When you drop an image into the tool, it's decoded, redrawn onto a canvas, and re-encoded into your chosen format — all on your device. No image data is ever sent to a server, because there is no server involved in the conversion at all.

Why we built it this way

Most online converters require uploading your file, waiting in a queue, and downloading the result from a server — which means your images pass through someone else's infrastructure. For a task as simple as changing a file format, that always felt like more than necessary. A browser can do this conversion itself, instantly, for free.

Who maintains this site

SmartPic Converter is an independently run project. If you spot an issue or have a suggestion for a format pair we should add, feel free to reach out via the contact details on our social channels.
