Quality or size limit: which should I use?
Use quality when you just want smaller files that still look good. Use asize limit when a website or form says something like “maximum 1 MB”. The tool then makes every photo fit under that limit.
Which format makes the smallest files?
| Format | File size | Best for |
|---|---|---|
| AVIF | Smallest | Modern websites |
| WebP | Small | Websites, sharing |
| JPG | Medium | Photos that must open everywhere |
| PNG | Large for photos | Screenshots, logos, transparency |
