Set your goal: optimal size by use
Choose image width and format based on your platform (blog, online store, social media).
Recommended widths by platform
| Platform | Recommended width | Reason |
|---|---|---|
| Blog posts | 600–800px | Readability and load speed |
| 1200px | Standard size | |
| 1080px | Mobile display size | |
| Thumbnails | ≤ 300px | List optimization |
Format comparison
JPEG — Best for photos. Quality 70–80% is usually sufficient, and file size is smallest.
PNG — Transparent background only. Avoid for regular photos (large file size).
WebP — Modern browsers. About 30% smaller than JPEG at same quality.
