About ImageCaddy

ImageCaddy is a set of free, focused image tools: format converters (including HEIC, TIFF and PDF), a circle cropper, an image splitter, an Instagram resizer and simple adjustments like blur and grayscale.

How it works

Every tool runs inside your web browser, using its built-in image features and the open-source libraries listed below. When you add a file, it's read and processed on your own device. It is never uploaded to a server. That's why the tools are fast, work with private photos, and need no account or upload limits.

What we're working on

We add new tools regularly. GIF, ICO (favicon) and SVG output are next.

Open-source software
