- Click Compress images and download them one by one or together as a ZIP.
About the Compress Image tool
Large photos slow down websites and get rejected by upload forms. Compressing an image removes detail your eyes won't notice, often cutting the file size by 60–80%. For the biggest savings, also limit the width — a phone photo resized to 1920 pixels wide still looks great on any screen but is a fraction of the size.

Frequently asked questions
What quality setting should I use?
Between 60% and 80% is ideal for most photos. Lower values make smaller files but can show blocky areas.
Should I choose JPG or WebP?
JPG works everywhere. WebP files are usually 25–35% smaller, keep transparent backgrounds, and work in all modern browsers.
What happens to transparent PNG backgrounds?
Choose WebP or PNG to keep transparency. Converting to JPG fills transparent areas with white.
Is there a limit on the number of images?
No. Add as many images as you like and download them all at once as a ZIP file.
