About

SpeedOf.Me is a free, browser-based internet speed test that measures download, upload, latency and jitter on any device: desktop, mobile, tablet, game console, smart TV or car. No app, no plugin, no download. Launched in 2011 as the first HTML5 speed test, it runs a single stream from your browser to neutral CDN edge servers in 130+ locations, so the result reflects real browsing performance instead of a lab-style peak. We call it Real-World Speed. Developers can embed the same engine with the SpeedOf.Me API: a few lines of JavaScript, white-label, with callbacks for every metric and an analytics dashboard for usage, geography and devices. Ready-to-run examples cover React, Vue, Angular, Electron, Flutter, iOS, Android and more. An MCP server and CLI (@speedofme/mcp) let AI agents and CI pipelines run real speed tests. The Internet Speed Atlas publishes real-world averages for 119 countries.

Pros & Cons from Real Users

Pros

  • Bringing a 20mb scan down to under 3mb without visible quality loss was impressive. The process ran fast and the output stayed readable across every page.
  • Encryption workflow is minimal: upload, set a password, choose print and edit permissions, download. No unnecessary screens or upsells between starting the process and getting a secured file back.
  • Custom page ranges with individual file naming kept everything organized from the start. Each output section opened cleanly, formatting held, and no content went missing at split boundaries across the entire document.
  • Fifteen product photos merged into one PDF with sharp resolution, correct ordering, and proper orientation on every page. Layout toggle between portrait and landscape handled mixed aspect ratios without cropping anything.
  • Highlighting and sticky notes render crisply without affecting page load times. Color coding works well for organizing feedback by category, and every markup exports exactly as placed when downloading the final version.

Cons

  • A compression strength selector with labeled presets would help users pick the right balance.
  • Expiring passwords or time-limited access would add flexibility for documents shared temporarily. Right now protection is permanent unless manually removed, which works but doesn't cover every sharing scenario cleanly.
  • A visual page picker where you click pages to define ranges would feel more intuitive than manual number entry. Counting pages on a 200-page document and typing ranges introduces avoidable room for human error.
  • Resolution presets labeled for specific use cases like "screen," "print," or "email" would make choosing output quality more intuitive than the current auto-setting, especially for users unfamiliar with DPI terminology.
  • Annotation search or filtering by type would help on heavily marked-up documents. Scrolling through forty pages to find a specific comment gets inefficient, especially when multiple reviewers have added their own notes.

Pros & Cons from Real Users
