Frequently Asked Questions

What image format is best for web? ▼
JPEG is best for photos, PNG for graphics with transparency, and WebP for modern browsers (better compression). Use the format that matches your content type.
How much can I compress an image without losing quality? ▼
For JPEG, 70-80% quality typically reduces file size by 60-80% with minimal visible difference. For PNG, lossless compression typically reduces size by 20-40%.

Yes. First resize to the maximum display size needed, then compress. Don't upload a 4000px image if it will only display at 800px.
