Frequently Asked Questions
What is lossless compression?
Lossless compression reduces file size by removing redundant or unnecessary data without changing any pixel values. The output image is mathematically identical to the input.
How much can lossless compression reduce file size?
Typically 10-30% for PNG files. For greater reductions, consider lossy compression at 90%+ quality, which is visually indistinguishable for most images.
What formats support lossless compression?
PNG and WebP both support lossless compression. JPEG is inherently lossy and cannot be compressed losslessly.
