  1. v1.6

    Elite tier + purchasable Vectorize API

    New
    • New Elite plan adds programmatic access to the PNG→SVG vectorizer over HTTP — convert raster art to clean SVG straight from your build pipeline.
    • Generate, rotate, and revoke API keys from a new account area, scoped per workspace.
    • A usage dashboard tracks calls, conversions, and remaining quota in real time.
  2. v1.5

    PNG → SVG Vectorizer

    New
    • Trace PNG, JPG, and WebP images into editable, infinitely scalable SVG paths — all in the browser, nothing uploaded.
    • Tune color count, path smoothing, and detail before exporting optimized SVG markup.
  3. v1.4

    Stripe subscriptions + billing portal

    New
    • Introduced Basic and Premium plans with Clerk-backed entitlements gating the catalog.
    • Self-serve billing portal lets you upgrade, downgrade, update payment methods, and view invoices.
  4. v1.3

    Marketing site + new information architecture

    Improved
    • Launched the public homepage, pricing, roadmap, and contact pages with a refreshed Toolumen identity.
    • Reorganized the tools catalog into clear categories so the right utility is one click away.
  5. v1.2

    Faster, lighter HEIC Converter

    Improved
    • Switched the decoder to lazy-loaded WASM so the page stays light until you drop a file.
    • Batch conversion now zips outputs and handles large iPhone exports without stalling.

  6. HEIC Converter

    New
    • Drag-drop iPhone HEIC files and convert to JPG, PNG, or WebP — batch, zipped, and never uploaded.

  7. Contrast Checker

    New
    • Check any two colors against WCAG AA and AAA, with the contrast ratio and a brand-safe suggestion in one click.

  8. Webflow Embed Sizer

    New
    • Minify an embed, measure real character and KB size, and confirm it fits Webflow’s embed cap before you paste it.

  9. Open Graph Preview

    New
    • See exactly how a link renders across Slack, iMessage, Twitter, LinkedIn, Discord, and Google.

  10. SEO + AEO Audit

    New
    • Paste a URL for a graded report on title, meta, canonical, OG, JSON-LD, h1, robots, sitemap, and llms.txt.
  11. v1.0

    Toolumen launches

    New
    • The first browser-first tools go live at toolumen.com — fast, private, and built to ship.
