A step-by-step guide for bloggers and content creators to optimize every image before publishing — reduce file size by 70% while keeping visual quality sharp.
Unoptimized images are the #1 cause of slow blog page speeds. A single 4MB JPEG from your phone camera can slow your page load by 3-5 seconds — destroying your Core Web Vitals score and bounce rate. Here's the complete workflow to fix this, entirely in your browser for free.
Step 1: Resize to the Right Dimensions
Most blog content areas are 800-1200px wide. Uploading a 4000px wide image just makes browsers scale it down — wasting bandwidth. Use the Image Resizer to set the exact width you need. For blog post feature images, 1200x630px is the ideal size for both web display and social media sharing.
Step 2: Compress Without Losing Quality
After resizing, run the image through the Image Compressor. Set quality to 75-80% — this typically reduces file size by 60-70% with no visible quality difference. For a photo that was 800KB after resizing, you should achieve 200-300KB.
Step 3: Convert to WebP
WebP is Google's modern image format — 25-35% smaller than JPEG at equivalent quality, and supported by all modern browsers. Use the JPG to WebP Converter for the final compression step. Your 250KB JPEG often becomes a 160KB WebP.
Step 4: Generate SEO Alt Text
Never skip alt text — it helps visually impaired users and tells search engines what your image is about. Use the AI Alt Text Generator to instantly create descriptive alt text for any image.
