FAQs

Will resizing reduce quality?
Making an image smaller (downscaling) usually keeps it sharp. Upscaling can look blurry. Compression quality (e.g. 80%) controls file size vs visual quality.
What format should I use for web?
WebP or AVIF when supported; JPEG for photos; PNG for graphics with transparency.
