What is Project52?

Project52 is a collection of web-based tools designed to help with the small but frequent 'clean up / convert / verify' tasks that happen in real work. You may need to merge or split PDFs for submission, resize or convert images to meet platform requirements, or clean up pasted text that contains awkward spacing and line breaks. In developer and operations workflows, it’s also common to inspect JSON responses, URL-encoded parameters, JWT claims, or Unix timestamps. Project52 focuses on helping you move from input to a usable result quickly, with clear page-level guidance so you can verify outcomes before you share or submit them.

What problems does it help reduce?

Tool categories

Each tool is built around a specific outcome. Reading the short guide on each page helps avoid common mistakes—especially when preparing files for submission. A practical workflow is: keep originals → generate a processed copy → verify before sending.

Privacy and processing approach

Where possible, inputs are processed in your browser to reduce unnecessary transfers. Some features (for example, URL preview) require a request to fetch metadata from external pages, and certain file workflows may involve server-side processing depending on the task. Each tool page includes notes about how inputs are handled. If you’re working with sensitive content, review the notes and avoid sharing confidential information unless it’s truly necessary.
