Compress Image
Reduce image file size while controlling quality
Auto mode keeps transparency lossless and uses photo compression for opaque images. Choose Photo/JPEG for smaller photos, Lossless PNG for diagrams or transparent artwork, or WebP for modern lossy compression.
Quality guide: 70–80% is the sweet spot for photos (large savings, no visible loss). Below 50% you'll start seeing JPEG artefacts. Above 90% gives diminishing returns.
