About

Tools that mind their own business.

Most "free" online converters ask you to upload your file to their server first. For a quick image resize or a one-off PDF merge, that always felt like more than the job called for — your file, sitting on someone else's server, for a task your own browser is perfectly capable of doing itself.

ConvertKro was built around a simple rule: if a browser can do it alone, it should. Every tool here — the QR generator, the image converter, the PDF tools, the product feed converter — runs entirely on your device. Nothing you upload is ever sent anywhere.

No accounts. No file uploads. No "sign up to continue." Just the tool, doing the one thing you opened it for.

ConvertKro currently has four tools, with more planned:

• QR Code Generator — links, text, WiFi, contact cards
• Image Converter & Compressor — PNG, JPG, WEBP
• PDF Tools — merge, split, convert to and from images
• Product Feed Converter — Shopify, WooCommerce, and more

The site is free to use and supported by advertising. If something breaks or you'd like a tool that isn't here yet, let us know.
