Smaller images load faster, upload faster and fit email limits. Set exact pixel dimensions or scale by percentage, and pick a format at the same time.
Which format should I choose?
| Format | Best for |
|---|---|
| JPG | Photos. Small files, no transparency. |
| PNG | Logos, screenshots and transparency. Larger files. |
| WebP | Web images. Smaller than JPG at similar quality. |
Tips
- Keep aspect ratio on to avoid stretched images.
- For web pages, 1,200 to 1,600 px wide is enough for most photos.
- Quality 75 to 85% is usually visually lossless.
- Making an image larger than the original does not add detail.
