FAQ

Will compression reduce image quality?

Default 80% quality looks virtually lossless and usually shrinks the file 60-80%. Raise the slider to 90-95% in quality mode for near-original fidelity.

Are JPEGs uploaded to a server?

No. All compression happens locally in your browser. Photos never leave your device and are cleared on refresh or close.

How many images can I compress at once?

Up to 20. Batch compression applies the same setting to all, then you can download them as a single ZIP.

Can I compress a JPG to a specific size?

Yes. Switch to target size mode, enter the KB you want (e.g. 200), and the tool auto-adjusts quality and dimensions to hit it.

Is JPG or WebP smaller?

At equal quality, WebP is typically 25-35% smaller than JPG. If your target platform supports WebP, choose WebP output for the smallest file.
