Two ways to make an image smaller
File size depends on two things: pixel dimensions and compression. To reduce image size, first scale the dimensions down - for example to 50% - then, for JPEG or WebP output, lower the quality slider. Each result shows its new file size in KB.

Frequently asked questions
How can I reduce an image file size?
Scale down the dimensions (for example to 50%) and, for JPEG or WebP, lower the quality slider. The new size in KB is shown for each result.
How do I reduce an image to a specific KB size?
Resize the dimensions first, then adjust the quality slider and check the KB shown next to each result until you reach your target.
Which format gives the smallest file?
JPEG and WebP compress photos far smaller than PNG. WebP is usually the smallest for a given quality.
Are my images uploaded anywhere?
No. Compression happens entirely in your browser, so your images are never uploaded or stored.
