How we build and test file tools

A transparent explanation of local processing, automated checks, browser testing, known limits, and result review.

Start with a real task, then test it

Each tool is built around one clear job and describes its expected input, output, and browser limits.

Project-generated fixtures cover the main workflow as well as empty files, invalid formats, incorrect page ranges, and other recoverable errors.

The current tools use browser capabilities and front-end libraries. Selected files are not sent to a PixelForge server.

Local processing depends on device memory and browser support, so damaged, encrypted, or unusually large files may not work.

Changes pass type checking, code-quality rules, unit tests, production builds, and checks for titles, headings, canonical links, and sitemap entries.

Important interfaces are reviewed in a real browser on desktop and mobile, in both light and dark themes.

Open the downloaded result and check page order, text, image orientation, special characters, and filenames before relying on it.
