Multilingual Word & Character Counter
Count words, characters, sentences, paragraphs, and estimate reading time with CJK Unicode support.
Case & Code Identifier Converter

Tool Selection Guide
Choose PDF Merger to concatenate files, PDF Splitter to extract ranges or burst pages, Word Counter to measure multilingual drafts, Case Converter to reshape identifiers and headings, and QR Code Generator when the output must be a scannable matrix rather than editable text.
Assemble vs disassemble PDFs
Merger combines independent documents into one file. Splitter carves ranges or single pages from one document, including ZIP bundles. Neither tool edits hidden annotations as a full PDF suite would.
Analyze text vs encode an optical code
Word Counter and Case Converter work with Unicode strings. QR generation turns content into a QR matrix with Reed-Solomon error correction that you can style; it is not a live analytics tracker.
