Control JPEG or WebP image export quality

This tool uses the browser image encoder. JPEG and WebP are lossy formats; lowering the quality slider may produce fewer bytes but can blur fine patterns, text, and high-contrast edges.

How to use this tool

Import the image you want to share or upload.
Select JPEG or WebP in Export Format.
Begin with a high quality setting, export once, and inspect the result.
Lower quality incrementally and compare actual file sizes until the result is acceptable.

Practical tips

For logos or text-heavy screenshots, test carefully: JPEG can add halos around fine edges.
WebP may be smaller than JPEG for some photos, but the exact outcome depends on the image and browser.
The download size cannot be guaranteed in advance because source complexity varies.

Common questions

Does the tool guarantee a certain KB size?

No. It offers quality control, not a target-file-size algorithm.

Why is the exported file larger?

Some source files were already optimized; re-encoding can increase their size.

Limitations: Transparent areas become an opaque background in JPEG; choose an appropriate format if transparency matters.
