ToolPix is a collection of free online tools built with one core principle: your files should never leave your device.
Every tool on this site processes your data entirely in your web browser using JavaScript. There is no server-side processing, no file uploads, no accounts, and no tracking of your files. When you compress an image, merge a PDF, or format JSON on ToolPix, the work happens locally on your computer — nothing is transmitted over the internet.
The internet is full of online tools that promise to be "free" but come with hidden costs: they upload your files to unknown servers, bombard you with pop-up ads, require you to create an account for basic functionality, or limit you to a handful of uses before demanding payment.
We found this frustrating. Simple tasks like resizing an image or merging two PDFs should not require trusting a third party with your files. Modern browsers are powerful enough to handle these tasks locally, so we built ToolPix to prove it.
ToolPix is built with vanilla JavaScript and static HTML. There are no frameworks, no backend servers, and no databases. The entire site is deployed as static files on Vercel's edge network, which means it loads fast from anywhere in the world and there is literally no server that could receive your files even if we wanted it to.
We use well-established open-source libraries for specialized tasks: pdf-lib for PDF manipulation, the Web Crypto API for hash generation, and the Canvas API for image processing. Everything else is standard browser APIs.
ToolPix currently includes 17 free tools across five categories:
Image Tools — Compress, resize, convert (PNG/JPG/WebP/BMP), and crop images.
PDF Tools — Merge multiple PDFs into one or split/extract specific pages.
Text Tools — Word counter, case converter (7 styles), text diff comparison, and lorem ipsum generator.
Developer Tools — JSON formatter and validator, Base64 encoder/decoder, SHA hash generator (SHA-1/256/384/512), color converter (HEX/RGB/HSL), and QR code generator.
SEO Tools — Meta tag generator (with Open Graph and Twitter Card support) and URL slug generator.
We know a huge part of our audience is PC gamers — people who need to compress screenshots for Discord, resize images for stream overlays, verify game file integrity with SHA hashes, edit JSON game configs, pick RGB values for their setup, and create QR codes for their server. We built ToolPix with you in mind. Check out our gaming guides for tips on getting the most out of these tools.
We use minimal analytics to understand which tools are most useful (so we can prioritize improvements) and serve non-intrusive ads to keep the site running. We never track individual users, never store your files, and never share any data with third parties beyond what is required for analytics and advertising. You can decline cookies and still use every tool on the site.
We are actively developing new tools and improving existing ones. Some features on our roadmap include a markdown editor, favicon generator, screenshot-to-code converter, and batch processing for Pro users. If you have suggestions for tools you would like to see, we would love to hear from you.
