How to Choose Compression Settings
Image compression is a balance between file size and visible quality. For photos, JPG or WebP usually gives the smallest result. For screenshots, logos, and images with text, PNG or WebP can keep edges sharper.
| Image type | Recommended format | Starting quality |
|---|---|---|
| Product photo | WebP or JPG | 0.75 to 0.85 |
| Blog image | WebP | 0.70 to 0.82 |
| Screenshot with text | PNG or WebP | 0.85 to 0.95 |
| Email attachment | JPG | 0.65 to 0.80 |
Common mistakes
Avoid compressing the same JPG many times because quality loss can stack up. If the result looks blurry, raise the quality slider or resize the image dimensions instead of lowering quality further.
