What This Tool Does

Reduce image file sizes without losing a single pixel of quality. Lossless compression reorganizes image data more efficiently — the output is identical to the input, pixel for pixel. Ideal for graphics, logos, screenshots, and any image where quality is non-negotiable. Typical savings are 10-30%.

Frequently Asked Questions

What's the difference between lossy and lossless compression?

Lossy compression removes some data permanently for larger file size reductions. Lossless compression reduces size without removing any data — the decompressed image is identical to the original.
