Exporting Compressed Images in GIMP
In GIMP, use File → Export As (not Save) to compress images:
- JPEG: Export As → choose .jpg → adjust Quality slider (75–85 recommended)
- PNG: Export As → choose .png → set Compression level (higher = smaller file, slower export)
- WebP: Export As → choose .webp → adjust quality and preset settings
Compression Strategy by Image Type
| Image type | Recommended export | Starting quality |
|---|---|---|
| Product photo or portrait | JPG or WebP | 78 to 85 |
| Screenshot with small text | PNG or lossless WebP | Lossless |
| Hero image for a web page | WebP | 72 to 82 |
| Email image | JPG | 65 to 75 |
Watch flat color areas, hair, skies, and small type when lowering quality. These are the first places where compression artifacts become obvious. If the file is still too large after compression, resize the image dimensions before reducing quality further.
