Learn
Plain-language guides behind the tools — what QR codes, JSON, and browser-based processing actually are, and how to use them well. For a step-by-step walkthrough of what happens when you use a tool, see how Tabreon works.
Privacy
Client-side vs. server-side processing
The difference between client-side (in-browser) and server-side data processing, and what it means for privacy.
Why browser-based file processing matters
Why processing files directly in the browser — instead of uploading them to a server — matters for privacy, speed, and reliability.
What data leaves your browser?
How to tell what data a web tool actually transmits, and the difference between the input you process and other data like analytics.
QR Codes
What is a QR code?
A plain-language explanation of what a QR code is, how it stores data, and how phones read it.
Static vs dynamic QR codes: what's the difference?
The difference between static QR codes (content baked in) and dynamic QR codes (redirect-based, editable, trackable).
QR code size and printing guide
How to size a QR code for print so it scans reliably, based on scan distance and code complexity.
QR code error correction explained
What QR code error correction levels (L, M, Q, H) mean and how much damage a code can tolerate and still scan.
PNG vs SVG for QR codes: which should you use?
When to export a QR code as PNG versus SVG, based on whether it will be used on screen or printed.
Developer
What is JSON?
A plain-language introduction to JSON — what it is, why it exists, and how it's structured.
JSON formatting vs. minification: what's the difference?
The difference between pretty-printing (formatting) JSON for readability and minifying it for size.
Best free JSON formatter: what to look for
How to choose a free JSON formatter: local processing, strict validation, format and minify, large-input handling, and no signup. A checklist, and how Tabreon measures up.
What is Base64 encoding?
A plain-language explanation of Base64 encoding — what it does, why it exists, and where it's used.
URL encoding explained
What URL encoding (percent-encoding) is, why it exists, and which characters it affects.
301 vs 302 vs 307 redirects: what's the difference?
The difference between 301, 302, and 307 HTTP redirects — which one preserves the request method, which one search engines treat as permanent, and when to use each.
Images
Image compression explained
How image compression reduces file size, and the difference between lossy and lossless compression.
Image resizing vs. compression: what's the difference?
The difference between resizing an image (changing its dimensions) and compressing it (reducing its file size at the same dimensions).
