Count, compare, replace and reformat plain text. Each tool describes its matching rules and editing limitations.
Resize, crop, convert, compress, watermark and sample images in your browser. Re-encoding can lose metadata or animation.
Merge, extract and render PDF pages, create PDFs from images and explore compression or password protection. Check output and feature limitations.
Inspect JSON, XML, encodings, tokens and patterns, or generate identifiers and passwords. Decoding and heuristic checks do not establish security.
Explore financial and payroll calculations under displayed assumptions. Some models are historical; verify current rules before filing or paying.
Compare business costs, pricing and planning scenarios, and generate names or codes. Estimates and generated identifiers need independent checks.
Explore EOQ, reorder points, turnover and pricing models, and generate internal SKUs or barcodes. Models do not connect to your inventory system.
Draft business documents and text-only PDFs, project revenue or convert currencies. Inspect exports and verify commercial or legal requirements.
Practical tutorials on developer tools, Indian finance, image optimization, and privacy-first web development.
Work through EOQ and reorder-point calculations, keep annual and daily demand consistent, and check supplier pack sizes, safety stock and inventory position.
Compare contribution timing and model assumptions without treating a growth projection as a promised return.
Distinguish an account balance, a projection and a claim entitlement before making a withdrawal decision.
Understand the arithmetic in a gratuity estimate and the eligibility details it cannot determine.
