Kaazo Guides

The reasoning behind the tools: limits, failure modes and better ways to check your output.

These guides explain the awkward parts around the tools—the trade-offs, failure modes and details a button label can't fit.

File and document work

• Browser-Based File Processing: What “Local” Really Means
  What stays on your device, what still loads from the web, and where browser memory becomes the real bottleneck.
• PDF Browser Tools: Which Job Needs Which Tool?
  Merge, crop, redact, OCR, flatten and convert PDFs without confusing one operation for another.
• OCR Accuracy: Fix the Scan Before Blaming the Engine
  Practical ways to improve OCR results—and the characters you should always verify by hand.
• JPG vs PNG vs WebP: Pick the Format by What You Need to Keep
  A practical comparison of compression, transparency, metadata and repeated re-encoding.
• EXIF and GPS Metadata: What a Photo Can Carry Without Showing You
  Dates, camera details and coordinates can travel inside a JPEG even when the visible image reveals nothing.
• Why PDF-to-Word and Word-to-PDF Layouts Shift
  PDF fixes a page; Word reflows a document. Understanding that mismatch explains most conversion surprises.
• CSV and JSON Conversion: Where Data Quietly Goes Wrong
  Headers, quoting, types and uneven rows are the boring details that decide whether a conversion is safe.
• SEO Generators vs Search Engines: What the Tools Can Actually Control
  Canonicals, robots rules, sitemaps and schema help implementation; Google still makes the crawling and indexing decisions.
• QR Code Reliability: Test the Version People Will Actually Scan
  Quiet zones, contrast, print size and payload checks matter more than a perfect desktop preview.
• Online Calculators: The Formula Can Be Right and the Decision Still Wrong
  How to use ROI, ROAS, EMI, CAGR, GST, VAT and other quick calculations without hiding assumptions.
• Text Cleaning Without Accidentally Changing Meaning
  Whitespace, line breaks, duplicate lines and Unicode can make simple cleanup less simple than it looks.
• Browser Security Utilities: Useful Jobs, Important Boundaries
  Passwords, hashes, UUIDs, signatures and redaction each solve a different security problem.
• Browser Video Editing: When It Works Well—and When to Stop Fighting the Tab
  Memory, codecs and export behaviour set the practical limits for in-browser editing.

Why these pages exist

A tool page should help you finish a job. A guide has more room to explain why the job behaves the way it does. That difference matters for PDF layout, OCR, metadata, search-engine signals and data conversion, where a technically valid output can still be the wrong practical result.

We update guides when a real tool limitation, user mistake or regression exposes something worth explaining.
