Why JPG works well for 100KB photos
JPG is widely accepted by upload forms and performs well for portraits, product photos, and scanned documents. A 100KB JPEG usually keeps enough detail for visual review while staying small enough for strict upload systems. Avoid recompressing the same JPEG many times because repeated compression can create visible artifacts.
Best JPG settings
- Use JPG for photos and portraits
- Max width: 1200–1600px
- Crop before compressing for sharper results
- Use WebP only if the target site accepts it
