FAQ
Compression questions
Quick answers about using our free Image Compressor.
No. All compression happens in your browser using the Canvas API. Your images never leave your device.
WEBP is usually 25 to 35% smaller than JPEG at the same visual quality and is supported by all modern browsers. Use PNG only when you need lossless graphics.
75 to 85% is the sweet spot for photos on the web. Most people cannot see a difference from the original, while file size often drops by 60% or more.
No. Re-encoding strips EXIF metadata, including camera details and GPS location, which also improves privacy.
PNG is lossless, so the quality slider does not apply. Convert to WEBP or JPEG, or resize the image, for big savings.
