80 is the sweet spot for blogs — much smaller files, no visible difference. Lower = smaller file, softer image. (PNG output ignores quality.)
Blog content rarely needs more than 1200 px wide.
WebP usually wins for photos. PNG keeps transparency.

Why image size matters for SEO
Images are usually the heaviest part of a blog page. One uncompressed phone photo can weigh 4–5 MB — more than the rest of the page put together. Heavy images slow your page down, and page speed is a Google ranking factor (Core Web Vitals). Slow pages also lose readers: on mobile, people leave a page that takes more than a few seconds to load.
Compressing an image before you upload it to WordPress is the single easiest speed win most bloggers have. The same photo at quality 80 is often 60–80% smaller, and readers cannot see the difference. Do it for every featured image and every in-post image, and your whole site gets faster.
How to use this compressor
- Drag your images onto the box above, or click it and choose files (up to 10 at once).
- Pick a quality — 80 is recommended for blog images. Choose a max width if your images are wider than your blog needs.
- Choose an output format. WebP gives the smallest files for most photos; keep PNG only when you need transparency.
- Compression runs automatically. Check the before/after preview and the % saved on each image.
- Click Download on each image and upload the compressed version to your site instead of the original.
JPG vs WebP vs PNG — which should you use?
| Format | Best for | File size | Transparency | Notes |
|---|---|---|---|---|
| JPEG (JPG) | Photos, featured images | Small | No | Works everywhere. Quality 75–85 looks identical to most readers. |
| WebP | Photos and graphics — the modern default | Smallest (often 25–35% below JPEG) | Yes | Supported by all modern browsers. Best choice for most blog images. |
| PNG | Logos, screenshots, graphics with text, transparency | Large for photos | No | Lossless, so text stays sharp — but never use PNG for big photos. |
Simple rule: photos → WebP (or JPEG), logos and screenshots → PNG, and always compress before you upload.
