Image compressor questions
How can I make an image file smaller?
Upload the image, reduce the quality value and process it. A lower value usually creates a smaller file, while detailed photos may need a higher setting.
Will image compression change the dimensions?
No. This compressor keeps the original pixel dimensions. Use the image resizer when you also need to change width or height.
Why does a PNG or AVIF input download as WebP?
JPEG inputs stay JPEG. Other supported inputs are exported as WebP so the quality setting has a real effect while transparent areas remain supported.
