About image compression
This tool shrinks your images by re-encoding them with a different quality setting and optionally a different format. The goal is to keep them looking almost the same while reducing file size.
Tip
Start with a higher quality and step down until the preview looks acceptable. That usually gives the smallest file size without visible damage.
Format
Keep original auto keeps the format for each image. You can also force JPEG, PNG, WebP or AVIF if you need a specific type.
Quality
Lower quality gives smaller files but can introduce artifacts. Around 70–85 is usually a good balance for photos.
Max width / height
If set, the image is resized so that it fits within these limits while preserving aspect ratio.
Per-image quality
Lets you fine-tune the quality for each file instead of using one global value.
Target size compression
This feature compresses the image based on your target size, automatically choosing the optimized compression quality needed to stay close to that size.
Bulk actions
You can either compress and download in one step, or compress everything first and download all compressed files later.
