Choose the Best Image Format
WebP usually provides efficient compression and supports transparency. JPG is ideal for photographs but does not support transparent backgrounds. PNG preserves transparency and uses lossless encoding, although PNG files can be larger.

Frequently Asked Questions
Is this image compressor free?
Yes. You can compress supported images for free without registering.
Are my images uploaded to a server?
No. Image processing happens locally in your browser.
Does compression reduce image quality?
JPG and WebP use lossy compression at typical quality settings, so some detail may be lost. PNG uses lossless encoding.
Why is my optimized image larger?
Some images are already highly optimized. Try WebP, a lower quality setting, or a smaller maximum width.
Can I compress transparent images?
Yes. Choose PNG or WebP to preserve transparency. JPG fills transparent areas with white.
