Compression features
• More efficient than JPG/PNG compression
• Both lossy and lossless compression modes

Frequently Asked Questions
How do I compress a WebP image to make it even smaller?
Upload the WebP file, set your preferred quality level, and download the optimized version. Because WebP supports both lossy and lossless modes, lowering the quality slider reduces file size at the cost of some fine detail — useful when bandwidth savings matter more than absolute pixel fidelity.
Is WebP lossy or lossless?
WebP supports both modes. Lossy WebP (based on VP8) is typically used for photographs and produces very small files with minor quality trade-offs. Lossless WebP (based on VP8L) preserves every pixel and is suited for graphics and text. Most web images use lossy WebP for the best size-to-quality ratio.
How do I reduce WebP file size for faster website loading?
Upload your WebP and lower the quality setting until you reach a file size within your performance budget. Combine smaller WebP files with proper caching headers for the best page-load improvement — the in-browser processing means no server round-trip is needed to prepare the optimized file.
Can I compress a WebP without converting it to JPG or PNG?
Yes — Image Machine outputs a compressed WebP file, not a converted one. This keeps all the format advantages, including better compression efficiency and wide browser support, while producing a file that is smaller than the version you started with.
Does re-compressing a WebP file damage quality significantly?
Every lossy compression pass discards some data, so re-encoding an already-lossy WebP will reduce quality further. To minimize generation loss, always start from the highest-quality source available and compress once to your target size, rather than repeatedly compressing from already-compressed files.
