What compressing a photo looks like
The picture looks the same at normal size, but the file is far lighter. That is the difference between a page that loads in a blink and one that crawls.
Compression changes how the picture is stored, not its dimensions. To make it physically smaller as well, use the Image Resizer.
How much to compress
Start in the middle and only go further if you are still over the limit.
| Level | What you get | Use it for |
|---|---|---|
| Lossless / highest quality | A smaller file, every pixel the same | Pictures you will edit again, or print. |
| Balanced | Much smaller; the difference is hard to see | Almost everything: websites, email, social posts. |
| Smallest | The lightest file; soft detail and some blocky areas on close inspection | Upload limits and very slow connections. |
Compression removes detail permanently. Always compress a copy.
What goes in, what comes out
| Format | As input | As output | Notes |
|---|---|---|---|
| JPG / JPEG | Yes | Yes | The biggest savings on photographs. |
| PNG | Yes | Yes | Savings are smaller; use WebP for more. |
| WebP | Yes | Yes | Already efficient. |
| AVIF | Yes | Yes | Smallest at the same quality. |
