FAQ
How does image compression work here?
Your image is drawn onto a browser canvas, then re-encoded as JPEG/WebP at the quality you choose. Lower quality means less detail but a smaller file.
How much quality is lost?
Around 0.8 quality is usually visually indistinguishable while cutting size significantly. Lower values shrink further but can show blockiness — check the preview before saving.
What formats are supported?
Most browser-readable images (JPG, PNG, WebP) can be loaded, and output can keep the original format or convert to JPEG/WebP/PNG. PNG is lossless, so quality only affects re-encoding, not compression ratio.
Is my photo uploaded to a server?
No. Loading, compressing, previewing and downloading all happen in your browser only — nothing is sent or stored on a server.
