PDF Tool

PDF is a print format that the internet adopted by accident, and almost every frustration with it follows from that.

The posts here explain the consequences. Why text in a PDF has no reflow, so it looks wrong on a phone and always will. Why a scanned PDF is a picture of text, not text, and why search finds nothing in it until OCR has been run. Why merging two PDFs can quietly triple the file size when both embed the same font. What actually gets destroyed when a compressor promises to shrink your document.

There is a workflow piece on going from Markdown notes to a clean, printable PDF without a word processor in the middle — useful if you write in plain text and need to hand in something that looks finished.

For students producing coursework, developers turning docs into deliverables, and anyone whose contract, medical record or ID scan should not be passing through a free online PDF service on its way to being merged.

The PDF Merge & Split Studio keeps the file on your machine; these posts explain what it is doing to it.
