CodeKitHub's answer
CodeKitHub's answer
Compared to single-purpose sites like JSONFormatter.org or CodeBeautify that only handle one task, CodeKitHub covers the same ground plus image, PDF, QR, and calculator tools in one place — useful if you regularly switch between different tool types during a workday.
Unlike FreeFormatter (which recently shut down its service), CodeKitHub's tools require no backend at all — everything runs as static, client-side JavaScript, so there's no server cost pressure driving ads, paywalls, or future shutdowns of the kind that killed similar sites.
If you need a tool site in a language other than English — Spanish, French, German, Japanese, Korean, Chinese, and others — CodeKitHub is one of the few free tool sites that actually localizes the full interface rather than just running it through machine translation on top of an English-only tool.
CodeKitHub's answer
CodeKitHub serves two overlapping groups:
Traffic data shows both groups in practice: technical tools (QR generator/decoder, Base64 encoder, JSON tools) draw developer-heavy referral sources like Hacker News and ChatGPT, alongside broader organic search traffic for everyday utility tasks.
CodeKitHub's answer
CodeKitHub started as a small set of browser-based developer utilities and grew into a 120+ tool collection covering JSON formatting, encoding, image/PDF processing, calculators and more. The core principle from the start was that every tool should run entirely client-side — no backend, no data leaving the user's browser — which keeps the tools fast, private, and cheap enough to run without ads getting in the way. The site has since expanded to 13 languages to serve users beyond English-speaking markets.

I mainly use offline means: organising all my files in a hierarchy of folders and using pureref (which I highly recommend) to make moodboards, and ofc an external hard drive to save backups. The only online means I use is google drive... Source: about 4 years ago
If you just want the image to be a transparent overlay while you draw 'through the image'(with it being unchanged) you can use something like Pureref(pureref.com) to set the image as always on top + turn opacity down a bit. Source: over 4 years ago
If you can’t get it to work inside of max, I thought of a free easy workaround you could try. I use the software pureref to manage and quickly access reference images. You could just resize an empty pureref window to cover your username.... Source: over 4 years ago
