TDN Converter Tools

Why waste time juggling multiple apps when one tool handles all your conversion needs?

Meet TDN Converter Tools — the all-in-one utility suite that transforms files, units, currencies, and data formats with zero friction. Whether you're a student, freelancer, or power user, this app eliminates the "wrong format" bottleneck. No more searching for separate converters, no more copy-pasting between tools. Everything lives in one clean, offline-ready interface.

What TDN Converter Tools actually does

File format conversion — convert documents, images, audio, and video between 50+ formats. PDF to Word, PNG to JPG, MP3 to WAV, or MP4 to GIF. Batch processing supported: select multiple files and convert them all at once.

Unit & currency converter — 200+ units across 12 categories: length, mass, volume, temperature, speed, pressure, energy, power, data storage, time, area, and cooking. Currency rates update via live API (requires internet). Includes historical rate lookup for the past 30 days.

Text & data transformer — encode/decode Base64, URL, HTML entities, and JSON. Convert between CSV, JSON, XML, and YAML. Extract text from images using built-in OCR (supports 15 languages). Generate QR codes and barcodes from any input.

Advanced calculator suite — scientific calculator, date/time difference calculator, tip calculator, percentage calculator, and a unit-aware equation solver. All calculations log to history for later reference.

Custom conversion profiles — save frequently used conversion pairs (e.g., Celsius→Fahrenheit, USD→EUR) as one-tap shortcuts. Create batch conversion templates for recurring tasks.
