Frequently Asked Questions
At moderate settings, no — modern lossy compression removes data your eye barely notices. Use the before/after preview to find the sweet spot for each image.
WebP usually beats both JPEG and PNG at the same visual quality. Use PNG when you need lossless output or full transparency support.
No. Compression runs in the browser, so private images stay on your device.
Lossless (PNG) when the image will be edited again, contains hard-edged art like pixel sprites or UI, or needs exact colors. Lossy is fine for photos and final web delivery, where small artifacts vanish into natural detail. Never re-edit from a lossy export — keep the original as your master.
No wider than they'll ever display: ~1920px covers full-width hero images, 2560px covers retina versions, and content images are usually fine at 800–1200px. Serving a 4000px camera photo into a 600px slot wastes bandwidth compression can't win back.
PNG size scales with pixel count and color complexity — a large, noisy, photographic PNG stays big because lossless can't discard detail. Either reduce dimensions or switch that image to WebP/JPEG; reserve PNG for graphics with flat color and transparency.
