Free online image compressor — shrink JPG and WebP in your browser
This free image compressor reduces file size so photos load faster on websites, WhatsApp, email, and forms. Upload a JPG, PNG, or WebP, pick a quality level and output format, preview the result, and download — with no account and no upload to a remote server.
How to compress an image
- Select an image from your device (up to 20 MB).
- Choose JPEG or WebP for the best size reduction, set the quality slider, then click Compress.
- Compare original vs compressed size, preview the result, and click Download.
When to use JPEG or WebP vs PNG
JPEG and WebP use lossy compression that usually cuts file size a lot. PNG is lossless — re-encoding as PNG often stays large or even grows, so prefer JPEG/WebP when size matters. Need a format change without tuning quality? Use our image converter. Need exact pixel dimensions? Use the image resizer.
Common uses
- Web pages — shrink hero images and product photos for faster loads.
- WhatsApp and email — stay under attachment limits without a blurry mess.
- Forms and portals — meet “max file size” requirements before upload.
Runs entirely in your browser
Your data never leaves your device — compression uses the HTML canvas API locally. Nothing is uploaded or stored on our servers.
