DevToolCore is a collection of 30 free browser-based tools for developers and SEO practitioners. The JSON tools format, validate, and minify payloads. The PDF tools compress documents to exact size limits for upload portals and count words without uploading the file. Image tools hit exact KB targets for forms with size caps. SEO tools analyze meta tags, check favicon setup, measure keyword density, and preview meta descriptions as search results. QR tools create codes and decode them before you scan. Everything runs client-side in the browser, so data stays on your device, and no account is ever required.
