Image Optimizer

How it works

1. Upload. Choose the image you want to optimize (up to 25 MB).
2. Optimize. Press Optimize — the image is re-encoded at web quality and metadata is stripped.
3. Download. Your lighter image downloads automatically in the same format.

About this tool

Image Optimizer is the one-click version of the compressor: it re-encodes your image at a sensible web-quality setting, strips the metadata that bloats a file, and keeps the same format, so you don't have to fiddle with sliders. It's aimed at the common job of making site images lighter and faster without thinking about settings. For full manual control over quality and output format, use the Image Compressor instead. No watermark, no signup, processed in memory.

What people use it for

• Make site images load faster with no decisions to make
• Strip GPS and camera metadata while shrinking a photo
• Batch-prep images for a blog at a sensible default
• Lighten a photo for email without choosing a quality
