About this tool Privacy, tips and file size

01 / PRIVATE

Made to stay local.

Your photo is processed in this browser. No upload is needed.

02 / FILE SIZE

Check the result.

PNG is lossless, and an encoded image can be larger than its source. The actual output size appears before download.

03 / COMPARE

Find your balance.

Compare before and result with the slider. A target size may reduce image dimensions.

Tool guide

Compress an image in your browser

Choose a JPEG, PNG or WebP image, then set a quality level or a maximum file size. The preview updates locally so you can compare the original with the result before downloading.

JPEG and WebP quality settings can reduce visual detail. PNG remains lossless. A tight size target may reduce image dimensions when quality alone cannot reach it.

How to use it

Choose a photo from your device.
Move the compression slider. Use More options for format or a size target.
Compare both sides, check the output size, then download the result.

Common questions

Does the photo leave my device?

No. Encoding runs in a browser Worker, and the download is created locally.

Why is the result sometimes larger?

Different formats and lossless PNG can use more bytes than the source. Check the displayed output size before downloading.
