Image compressor questions
What quality should I use?
For most photos, a quality between 70 and 85 looks almost the same as the original at a much smaller file size. Check the downloaded file and adjust if you see blur or blocky areas.
Why did a file get bigger?
Images that are already well compressed, or simple graphics saved as PNG, can grow when re-encoded. The tool tells you, so you can keep the original.
Does resizing help as much as compression?
Often more. An image shown 800 px wide on the page but saved 4000 px wide wastes a lot of data, so setting a maximum width is one of the biggest savings.
