About this tool
Big photos slow down websites and fail to upload on forms that ask for "under 200 KB". This compressor re-encodes your image in your own browser, so nothing is uploaded anywhere. Move the quality slider until the size is right and download the result.
Frequently asked questions
Are my images uploaded to a server?
No. Compression runs entirely in your browser using the Canvas API, so your photos stay on your device.
What quality should I choose?
75–85% keeps photos looking the same to the eye while cutting the size by half or more. Go lower for thumbnails.
How do I get an image under 100 KB?
Use WebP or JPG, lower the quality to around 60% and, if needed, reduce the width with our Image Resizer first.
