About PXLTool
PXLTool is a growing collection of free online design utilities, originally built for the Korean design community and now expanding to English-speaking users. Every tool runs entirely in your browser using the Canvas API and File API — your images and inputs never touch our servers.
We currently offer 25+ tools in English (with more on the way) covering color palette generation, image resizing and conversion, CSS code generators, QR codes, OG image makers, and more. The full Korean version offers 129+ tools including Korea-specific utilities for Hangul fonts, Korean passport photos, and Naver Blog assets.

🔐 Privacy by design
PXLTool is built around the principle that your images and data should never leave your device. All processing — image resizing, color extraction, text conversion — happens locally in your browser. We don't have a database, we don't store your uploads, and we don't track individual users. The site is monetized only through Google AdSense ads.

Frequently Asked Questions
Is PXLTool really free?
Yes, every tool is completely free with no sign-up, no paywall, and no hidden fees. The site is supported by Google AdSense advertisements only.
Are my images uploaded to your server?
No. All image processing happens in your browser via the Canvas API. Your files never leave your device. Even sensitive material like company logos or personal photos are safe to use.
Can I use the outputs commercially?
Yes. All output (palettes, CSS code, images, QR codes, etc.) is yours to use for any purpose, including commercial work. No attribution required.
What browsers are supported?
All modern browsers — Chrome, Edge, Safari, Firefox, Opera. Some advanced features (AVIF, certain filters) require browsers from 2022 or later. Internet Explorer is not supported.
Why are there fewer tools in English than in Korean?
PXLTool started as a Korean-language site and is gradually being translated. The 25+ English tools cover the most universally useful utilities. Korea-specific tools (Hangul fonts, Korean passport photos, Naver Blog assets, etc.) remain Korean-only because they're not useful internationally.
