Abect Developer Tools

Abect is a collection of 53 browser-based developer utilities: text and code converters (HTML to Markdown, JSON to CSV), image format converters and compressors, a favicon generator, QR code generators, and SEO schema markup generators. Everything runs client-side; the site states no files are uploaded to a server and no data is transmitted over the network. It is free, with no signup, file size limits or watermarks.
