CHECK

Open the downloaded file and confirm that its pixel dimensions match the source and that the actual media type matches the chosen extension.
LIMITS

FAQ
Frequently asked
Why does lowering the quality slider have little effect on PNG output?
PNG is normally lossless and does not use the same quality parameter as JPEG or WebP. Choose a lossy WebP or JPG output when a smaller file matters more than exact pixels.
