FAQ
How much can I reduce image file size?
JPEG images can typically be compressed 40–80% with no visible quality loss. PNGs with few colors compress even more.
What is the difference between lossy and lossless compression?
Lossy (JPEG) permanently removes some data for smaller files. Lossless (PNG) reduces size without removing any data — the image is identical to the original.
Should I use JPEG, PNG, or WebP?
WebP offers the best compression for most use cases. Use JPEG for photos and WebP/PNG for graphics with transparency.
