Questions
What's the best format for the web?
WebP and AVIF give the smallest files at high quality. Use JPG for broad compatibility and PNG when you need transparency.
Does resizing keep things crisp?
Yes — high-quality resampling keeps edges clean. Locking the aspect ratio avoids stretching.
Are files uploaded?
No. Conversion and resizing happen on your device.
