Founder of Jaggaro
Punjab, India
Pritam Brar is the founder of Jaggaro — the independent software company behind SnapToolz. He builds privacy-first browser tools, writes long-form technical guides on file formats, WebAssembly, and applied cryptography, and is the editorial voice behind every article on this site.
Every guide on this site is researched, written, and maintained by Pritam personally — not auto-generated, not outsourced. Articles cite primary sources (RFCs, OWASP, NIST, W3C, WHO) so claims can be checked independently, and every long-form piece links back to the actual SnapToolz tool that implements the technique under discussion.

AES-256-GCM encryption explained — what GCM mode actually buys you
AES is the cipher. GCM is the mode that makes it safe to use. Here's the difference, and why getting the nonce wrong is the bug that ends careers.
JWT explained — anatomy, security pitfalls, and what to check in a token
Three base64url-encoded parts joined by dots. Most of the bugs aren't in the format — they're in how people verify it.
EMI / loan calculator — the math behind your monthly payment
Where the EMI formula comes from, why the same rate can cost wildly different totals, and how a single extra payment per year shaves years off a mortgage.
Understanding BMI — what the number actually measures and what it ignores
BMI was invented in the 1830s for population statistics, not for diagnosing individuals. Here's what it really tells you, and what it leaves out.
JPG vs PNG vs WebP vs AVIF — the 2026 image format decision guide
Four formats, four different strengths, and a lot of wrong defaults out there. Here's which to use for photos, graphics, the web, email, and your phone — with real file-size numbers.
The complete guide to PDF compression — algorithms, trade-offs, and how to hit a target size
What's actually happening inside a PDF when you shrink it, why some files refuse to get smaller, and how to land on 100 KB, 1 MB, or any other ceiling without ruining the file.

JSON, Base64, regex, hash, diff, JWT — the everyday utilities developers reach for, all in one place, all local.
A browser-only image pipeline that never touches a server
Resize, compress, strip EXIF, convert format — the full prep workflow for social, blog, and email images.
Optimize PDFs for email — without uploading them anywhere
Mail servers have a 25 MB hard cap. Here's how to combine, shrink, and send a clean PDF entirely in your browser.
Why local-first tools are faster, safer, and more dependable
