About Zevqi

Zevqi is a growing collection of free utilities for the small jobs that interrupt a workday: shrinking a PDF so it fits an email, converting a WebP image that a website refuses to accept, formatting a blob of JSON, or generating a password you do not have to invent yourself. Every tool is built to do one thing well, with no signup and no watermark.

Who is behind it

Zevqi is founded, owned and run by Neha Singh. Neha Singh designs the tools, writes the guides on the blog and answers every email sent to hello@zevqi.com. You can follow along, send feedback or request a tool on X: @heynehasingh.

Why it exists

Most online file tools make you upload your documents to a server you know nothing about, then bury the result behind a signup wall or a watermark. That is a poor trade for something as ordinary as merging two PDFs. Zevqi exists to offer the opposite: fast tools, clear explanations and respect for your files.

What we believe

• Common tasks should take one click, not five.
• Your files should stay yours. When the work can be done inside your browser, it is, and the file never reaches our servers.
• A tool is only useful if you understand what it did. That is why each tool page explains how it works, what its limits are and what to try if the result is not what you expected.
• Honest limits beat vague promises. If a tool cannot do something, we say so.

How the tools are built and tested

Image and PDF tools run on your device using the browser’s own canvas and well-known open-source libraries such as pdf-lib and qrcode. Password and UUID generation use the browser’s cryptographically secure random number generator. New tools and changes are tested against real-world files — phone photos, scanned documents, large exports — before they are published, and the guides on the blog are written from that hands-on testing.

How the site is funded

Zevqi is free to use. To cover hosting and development we display advertising through Google AdSense. Ads never see the contents of your files, and they are kept separate from the tools themselves. Details are in our privacy policy.
