  • How Long Does It Take to Read a Blog Post? Reading Speed Facts

    How Long Does It Take to Read a Blog Post? Reading Speed Facts

    How Google measures reading time

    Google’s index uses roughly 130 words per minute for plain text and factors scroll behaviour too. Medium calculates at 238 wpm. Whichever you publish on, knowing your article’s true duration helps you plan structure and ad placement.

    Average reading speeds

    • Skimming: 400–700 wpm
    • Casual adult reading: 200–250 wpm
    • Focused study reading: 100–150 wpm
    • Spending on a web page: only ~20% of words get read

    Why reading time matters for SEO

    Longer dwell time signals satisfaction. If your estimated read time is 6 minutes but analytics shows 40 seconds, your intro, headings or formatting are failing — not your topic. Break walls of text, add jump links, and put the answer first.

    Speed up your own comprehension

    1. Preview headings before reading line-by-line.
    2. Read the conclusion first, then decide if the body adds value.
    3. Minimise subvocalising by tracking with your cursor.

    Estimate your article’s read time

    Drop your draft into the free Reading Time Calculator — it counts words and converts them to minutes at 238 wpm. Pair it with the Word Counter for character-level stats.

  • How to Resize Images Without Losing Quality (Complete Guide)

    How to Resize Images Without Losing Quality (Complete Guide)

    Why image size decides your page speed

    Oversized images are the #1 cause of slow pages. A 4,000-pixel photo exported at 5 MB can usually become a 1,500-pixel WebP file under 200 KB with no visible quality loss — that’s Core Web Vitals points and better search performance.

    Ideal dimensions cheat sheet

    • Blog hero image: 1,200 × 675 px (16:9)
    • Featured/social share image: 1,200 × 630 px
    • Instagram square: 1,080 × 1,080 px
    • Instagram story / Reels: 1,080 × 1,920 px
    • YouTube thumbnail: 1,280 × 720 px
    • Website banner: 1,920 × 600 px max

    JPEG vs PNG vs WebP

    • JPEG: photos, 80–85% quality is the sweet spot
    • PNG: logos, screenshots, anything needing transparency
    • WebP: best compression for modern browsers — typically 30% smaller than JPEG

    Resize without losing quality — 5 steps

    1. Start from the highest-resolution original.
    2. Resize to the exact display size (never larger).
    3. Export as WebP at 80–85% quality, or JPEG at 85%.
    4. Strip EXIF metadata to shave extra kilobytes.
    5. Always add alt text when you upload — it helps SEO and accessibility.

    Do it privately, in your browser

    Our Image Resizer processes everything locally — your files are never uploaded to a server, which matters if you edit client work or confidential images. For video creators, grab thumbnails with the YouTube Thumbnail Downloader.
