25 free PDF and image tools that run inside your browser. Compress, convert, merge, split and sign files without sending them to a processing server, creating an account or adding a watermark. The privacy claim is narrow and testable: the site uses normal network requests, but the file you select is not uploaded for processing.
I built shrink.run because a quick PDF or image job should not require handing the file to a processing server.
The site currently has 25 free tools for images and PDFs. They run in the browser with JavaScript and WebAssembly, require no account, and add no watermark. The privacy claim is deliberately narrow and testable: the page and processing engines use ordinary network requests, but the file you select is not uploaded for processing. There is a guide showing how to verify that in the browser network panel.
I would especially value feedback on mobile use, which tools are missing, and whether the local-processing explanation is clear before a file is selected.
