Evergreen guides for the work that happens around our tools — format decisions, workflow stacking, and the small details that separate a good output from a great one.
People who handle files for work and want to get them right the first time. That includes office staff sending contracts and ID copies, people who publish images to the web, and developers who decode tokens and convert data between formats. Each guide is short. It explains the decision behind a task, like which format to pick or how far to compress, then points to the tools that do it.
The file tools these guides point to run in your browser, so your file stays on your device. The guides say where that makes a real difference, mostly with documents you would not want sitting on someone else's server.
Why PDF holds its layout on every device, and why that same rigidity makes it hard to edit. It explains the trade between lossless compression, which strips metadata and duplicate data without touching a pixel, and lossy compression, which shrinks the images inside. It ends with the safest way to handle contracts and financial PDFs: keep them off servers you do not control. The featured workflow walks through preparing a document to send, from blacking out what the recipient does not need to getting the file under an email size limit.

When to use JPG, PNG, or WebP. PNG keeps every pixel and suits screenshots and graphics with text. JPG is built for photos. WebP handles both and supports transparency. The guide also covers why heavy images slow pages down, and how that shows up in Largest Contentful Paint, one of the Core Web Vitals Google measures. The featured workflow resizes one original into posts for social platforms, with a WebP copy for the web.

Why files get bloated in the first place: embedded images, full fonts, thumbnails, and leftover save history. It lays out the three levers, in order: structural cleanup that changes nothing visible, downsampling images to the resolution the reader needs (150 DPI for screens, 300 for office printing), and recompressing them. It also says when not to compress hard. Legal filings, technical drawings, and scans with a text layer can break. For images, it makes one rule clear: resize first, then compress.

A working guide to the formats developers and analysts handle every day: JSON, CSV, Base64, URL encoding, and JSON Web Tokens. It covers the syntax mistakes that silently break JSON, how CSV bridges spreadsheets and code, and why Base64 and URL encoding hide nothing, since anyone can decode them. The JWT section explains that decoding a token only reads its claims. It does not verify the signature, and no decoder should ask for your secret key.

The small jobs that keep files clean and safe to share. Photos and documents carry hidden details like author names, GPS coordinates, and revision history, and the guide shows what to strip before sending. It covers why SVG exports from design tools carry extra weight an optimizer can remove, how live word and character counts help you hit platform limits, and why a password from the browser's Web Crypto API is safer than one built with Math.random().
