Tips for online shops and blogs
- Exact size (crop to fill) makes every product image the same shape for a tidy shop grid.
- Name files with keywords, such as blue-running-shoes-{n}, to help image SEO.
- WebP at 80–85% keeps pages fast without visible quality loss.
- Leave “Allow enlarging” off so small images don’t turn blurry.
Frequently asked questions
How many images can I process?
There’s no fixed limit. Very large batches depend on your device’s memory – try batches of 50–100 on a phone.
What does {n} do in the file name?
It adds a number, such as 01, 02, 03, so files stay in order.
Are my images uploaded?
No. Everything is processed in your browser.
