JSONFormatter.org CodeWizToolsCodeWizTools's answer:
CodeWizTools runs 100% in the browser — no file uploads, no server processing, no login required. Every tool from PDF merger to CGPA calculator processes data locally on the user's device. Most competing tools upload your files to their servers. CodeWizTools never does. Your PDFs, images, code, and academic data stay completely private on your device.
CodeWizTools's answer:
Three reasons:
Privacy — Files and data never leave your device. No server uploads, no logs, no tracking. Competitors like Smallpdf and ILovePDF upload your documents to their cloud.
Speed — No server round-trips. Processing happens instantly in your browser tab. No waiting for uploads or downloads from a remote server.
Zero friction — No account, no email, no free trial countdown. Open the tool, use it, close the tab. 18 tools accessible in one click.
CodeWizTools's answer:
CodeWizTools started from a simple frustration — every useful online tool either requires an account, uploads your files to a server, or puts essential features behind a paywall.
A Pakistani developer who regularly works with JSON, Base64, and PDF tools noticed that students in Pakistan face the same problem — they need to merge PDFs for assignments, compress files for LMS portals, and calculate attendance margins, but existing tools are either paid, slow, or require creating accounts.
CodeWizTools was built to solve this — 18 utilities that run entirely in the browser, free forever, with zero data leaving the user's device. The tools are designed around real developer and student workflows, not generic use cases.
CodeWizTools's answer:
Two main audiences:
Developers — frontend and backend developers who need quick utilities during their workflow. JSON formatting, Base64 encoding, URL encoding, RGBA color picking, MD5 hashing, password generation, and Lorem Ipsum generation are daily needs for developers building and debugging web applications.
University students in Pakistan and South Asia — students who need to merge PDFs for assignment submissions, compress files for LMS portals, calculate CGPA and attendance percentage, and batch-rename files before submission. These tools are specifically built around the workflows of students at universities like FAST, NUST, COMSATS, and UET.

3. JSON Formatter The GeoJSON file I used is super hefty, holding nested geographical information about country border locations as coordinate pairs, and information on country geometry, name etc. There are any number of ways you can show this file to get it to make sense, but I found another online tool that helped me break it down into readable chunks was JSON Formatter. It also helps validate JSON, useful if... - Source: dev.to / about 2 years ago
Hi HN, Simple online tools on the web have become unnecessary greedy. For example, * https://jsonformatter.org/ displays 7 ads on page load * https://convertcase.net/ had 4 ads plus a Google Vignette. And many more sites do the same thing. It's just noisy, which is why I created this VS Code Extension where you don't need to even leave your editor for your small web operations. I also built a Desktop app and an... - Source: Hacker News / about 2 years ago
