About K4Converter

Our Mission

K4Converter was created with one simple goal: to make everyday file conversions fast, free and private. Whether you need to turn a PNG into a JPG for an email, shrink images for your website, or combine photos into a PDF, you shouldn't have to create an account, wait in an upload queue or worry about who can see your files.

How We're Different

Most online converters upload your files to their servers. K4Converter works differently: our tools run entirely inside your web browser using modern web technology. Your files are processed on your own device and are never uploaded, stored or shared. That means faster results and complete peace of mind.

What We Offer

• Image converters — change PNG, JPG and WebP images between formats and into PDF.
• Image tools — compress and resize images (coming soon).
• Everyday converters — units, time, temperature and numbers (coming soon).

We add new tools regularly based on what our users need most. Have an idea for a converter? Let us know.

Who Builds K4Converter

K4Converter is designed and built by Prakhar Singh, a software engineer who works on web applications every day. After getting frustrated with converters that upload private files, cover pages in pop-ups and add watermarks, he built a faster and more private alternative where every tool runs entirely in your browser.

Every tool is tested on Chrome, Safari, Edge and Firefox across desktop and mobile before it goes live. You can connect with Prakhar on LinkedIn, see more of his work on his portfolio, or email prakharsingh2809@gmail.com.

Free for Everyone

All K4Converter tools are free to use. We keep the site running through non-intrusive advertising, which allows us to keep every tool free with no limits and no watermarks.
