Which format keeps the most quality?
WebP usually compresses smallest for the same visual quality. PNG is lossless, so the quality slider does nothing there, it just optimizes the file structure.
How do I pick the right quality?
Drag the slider and check the preview before downloading. There's no one right number, it depends on the image.
How small can I make an image without it looking bad?
Around 70 to 80 percent quality is the usual sweet spot for photos. Drop the slider until the preview looks wrong, then go back one step.
Does this upload my files anywhere?
No. Everything runs in your browser. Files never leave your device, there's no server to send them to, and no account or log.
