Why did my PNG barely shrink?

PNG is lossless, so there is little to remove. Convert it to WebP or JPG, or reduce its dimensions, for a large saving.

How does the target size work?

Quality is reduced step by step until the file fits. If the lowest acceptable quality is still too large, the dimensions are reduced as well.

Are my images uploaded?

No. Images are decoded, processed and re-encoded by your browser on your own device. They are never sent to a server, and closing the tab discards them.

Can I process several images at once?

Yes. Add as many as you need (up to 50), then download them one by one or all together as a ZIP file.
