A lightweight tool for extracting images from YouTube without ads, sign‑ups, or watermarks.

• Paste any YouTube URL → get the thumbnail instantly.
• Available resolutions:
  • HD (1280 × 720)
  • SD (640 × 480)
  • Default size
• Download channel profile pictures in full resolution.
• Download channel banner/cover art at full size (2560 × 1440).
• Works on videos, Shorts, live streams, and older videos.
• Zero ads, zero signup, zero watermarks.

How it works: Uses YouTube’s image CDN directly instead of scraping the page, providing near‑instant results for any public video.

Quick CPS Test – Clicks‑per‑Second Measurement

Link: https://quickcpstest.com

A no‑frills CPS tester that avoids the input lag common in other tools.

• Measures CPS with 0‑latency click detection.
• Test modes: 1 s, 5 s, 10 s, 60 s, 100 clicks.
• Tracks personal best and average CPS.
• Clean UI with zero ads or distractions.
• Fully functional on mobile (touch events).

Implementation details: Uses raw mousedown events instead of click events to eliminate the browser’s built‑in click delay, and removes unnecessary DOM reflows during the test interval.

Takeaways

• Simple tools that focus on a single purpose tend to be adopted quickly.
• Performance is a feature: users notice instantly when a tool feels fast versus sluggish.
• SEO from day one matters—clean URLs, fast load times, and descriptive meta tags help even small utilities gain visibility.

If you try either tool, feel free to share feedback, especially regarding edge cases or bugs. Continuous improvement is the goal.
