Frequently asked questions

What quality setting should I use?
For web use: 70–80% gives the best balance of size and quality. For sharing on social media: 80–85%. For archiving or printing: 90–95%. Below 60% you'll see visible artifacts on photos.
What is the difference between JPEG and WebP?
WebP is a modern format from Google that typically achieves 25–35% smaller files than JPEG at equivalent visual quality. WebP is supported in all modern browsers. Use WebP for web projects, JPEG for maximum compatibility.
Why is my PNG file larger after compression?
PNG is lossless — this tool can't meaningfully reduce its size without changing the format. Convert PNG to WebP or JPEG for major size reductions. PNG output here includes a quality baseline; use dedicated PNG optimisers (like pngquant) for true lossless compression.
