Editorial interest 78/100 Selection signal · not a rating of the site

A free collection of in-browser utilities for converting files, cleaning SVGs, merging PDFs, formatting data, generating codes, and more.

Landing page captured for the 2026-09-08 issue.

Field notes

The workbench groups eleven browser utilities behind a repeated “Open tool” interface rather than sending visitors to separate products. Its image converter offers sixteen output choices, including AVIF, ICO, embedded Base64 HTML, CSS background-image code, and grayscale variants, while the data tools handle JSON prettification and JSON-to-CSV conversion. The page also exposes developer-facing tasks such as SVG cleanup into React JSX and SHA-1 through SHA-512 hashing.
