Privacy

Your photos are not uploaded. Opening, cropping, rotating, resizing, batch cropping and zipping all run in your browser with the Canvas API. Image files are not sent to a server, and they are gone when you close the tab.

The optional alt-text & caption writer

If you open “Write alt text & a caption” and press Write, a small JPEG preview of your current crop (at most 512 px wide), the chosen platform and tone, and any context you typed are sent to our server. The server forwards them to an AI model through Vercel AI Gateway and streams back the text. We don’t save the preview or the result. Your IP address is kept in memory for a few minutes to limit abuse.

What’s stored on your device

CropMaster remembers your last preset, file format and quality in your browser’s localStorage, so they are ready next time. No images are stored. You can clear it here:
