FAQ
Does compression reduce image quality?
Yes, lossy compression reduces quality slightly to shrink file size. You control the balance with the quality slider — 80% usually offers great size savings with minimal visible difference.
Are my images uploaded to a server?
No. All compression happens in your browser using the Canvas API. Images never leave your device, ensuring complete privacy.
Which formats can I compress?
JPG, PNG, and WebP. JPG and WebP support quality adjustment, while PNG uses lossless compression.

How Image Compression Works

Image compression reduces file size by removing data the human eye is less likely to notice. Lossy compression (used for JPG and WebP) discards some image data permanently, while lossless compression (PNG) reduces size without quality loss but achieves smaller reductions.

The quality slider controls the compression level. At 80% quality, most images retain excellent visual quality while reducing file size by 50-70%. Lower settings produce smaller files but may introduce visible artifacts, especially in areas with fine detail or gradients.

Compressing images is essential for faster website loading, easier email sharing, and saving storage space. This tool processes everything in your browser using the Canvas API, so your images remain completely private.
