How to compress images
- Choose one or more images (JPG, PNG, WebP, GIF).
- Pick a quality — 70–80 is a good balance for photos on websites.
- Optionally set a maximum width, e.g. 1920 px, to shrink very large photos.
- Download each image or all of them as a ZIP.
Which format gives the smallest files?
| Format | Best for |
|---|---|
| WebP | Photos and graphics on the web — usually 25–35 % smaller than JPG |
| JPG | Photos where maximum compatibility matters |
| PNG | Screenshots, logos and images that need lossless quality |
By default PNG photos are converted to WebP, which keeps transparency and is far smaller. If a compressed file would end up larger than the original, the original is kept.
Private by design
Compression runs on your device with the browser's own image encoder — no file ever leaves your computer, so it is safe for private photos and client work.

At quality 75–85 the difference is usually invisible on screen, while the file becomes much smaller.
How many images can I compress?
As many as your device can handle; dozens of photos at once work well on modern computers and phones.
