Guides to the tasks the tools here are for — what actually works, what does not, and why. Written against what each tool really does, so nothing below promises something the tool cannot deliver.

Read the guideEvery guide exists to answer a question a tool page cannot answer well at the same time as being a tool. A tool page should let you do the thing; a guide can explain why the thing behaves the way it does — why a QR code that looks fine will not scan off a printed card, why splitting a PDF beats compressing it, what a HEIC conversion actually costs you.
They are written against what the tools genuinely do. Where something is not possible — recovering the page under a flattened watermark, reading handwriting with OCR, undoing JPEG compression — the guide says so rather than routing you to a tool that will fail quietly. Limitations are more useful than features when you are trying to finish a task.
Start from a category if you are not sure what you need: PDF tools, image tools, OCR and extraction, text and data, or developer utilities. Or see every tool in one list.
