Frequently Asked Questions
It depends on the compression level. At high quality settings (80–90%), the visual difference is usually invisible to the human eye while reducing file size by 30–60%. At lower quality settings, you will see artefacts and blurring. The quality slider lets you find the right balance for your use case.
For web use, 75–85 is the recommended range — it produces significant file size reduction with minimal visible quality loss. For print, stay at 90 or above. For thumbnails and small previews, you can go as low as 60 without noticeable degradation.
Set the quality slider to 85 or higher. At these levels, compression is nearly lossless to the human eye but still reduces file size. The tool shows the before and after file sizes so you can see exactly how much you are saving.
This tool compresses JPG, PNG, and WebP images. The output is always a JPG file. If you need to compress and keep the PNG or WebP format, use the Image Format Converter tool after compressing.
Typical reductions are 30–70% depending on the original image content and your quality setting. Images with large flat areas of color (like graphics and illustrations) compress more aggressively than photographs with lots of detail.
