Convert TIFF to PNG

How it works

1. Drop a .tiff file (or any image) onto the page.
2. The PNG output preset is already selected — hit Convert Now.
3. Download the result. The whole conversion ran in your browser via WebCodecs or FFmpeg.wasm. No file left your device.

Why convert TIFF to PNG?

Convert TIFF to PNG. PNG is lossless like TIFF but with much smaller files and universal browser support.

Is my file uploaded anywhere?

No. poqpoq is a static site — the page you're looking at is a bunch of JavaScript your browser downloaded once. It runs entirely on your device. There is no upload endpoint. When you open your browser's Network tab during a conversion, you'll see zero requests going out.
