Compress Image
Reduce the file size of your photos and images: adjust quality and the maximum dimension, re-encode as JPEG or WebP, and see the before/after size and savings instantly. Compression runs entirely in your browser (on your device) — your image is never uploaded. Ideal for email, WhatsApp and the web; no signup or installation needed.
Frequently Asked Questions
How do I compress an image?
Upload your images, choose the quality and maximum dimension, and click 'Compress'; download the smaller version of each image. It happens on your device.
Is my image uploaded to a server?
No. Compression runs entirely in your browser; your image is never sent to the internet and stays 100% private.
Which formats are supported?
You can upload JPG, PNG and WebP, and export as JPEG or WebP. WebP usually produces a smaller file at the same quality.
Will quality drop?
You control the balance with the quality slider. Around 70% gives a big size reduction with loss that's usually invisible for photos.
Is compressing images free?
Yes. It's free and needs no signup or installation; it runs directly in the browser and can process several images at once.
