Compress Image

Shrink JPG, PNG, and WebP images to smaller files while keeping them sharp.

About Compress Image

Large photos slow down web pages, fill inboxes, and hit upload limits. Compressing an image keeps the same dimensions but removes data the eye barely notices, so the file gets smaller while still looking good.

Upload a JPG, PNG, or WebP, set the quality level from 1 to 100 (85 is a sensible default), and pick the output format. Lower quality means a smaller file with more visible artifacts; higher quality keeps detail at the cost of size. Converting a photo to WebP often saves the most space for the same visual quality.

Web developers compress hero images and product photos to improve load time and Core Web Vitals; everyone else uses it to fit attachments under email and form limits. For photographs, JPG or WebP work best; for screenshots and graphics with sharp edges or transparency, PNG or WebP preserve quality better.

Frequently asked questions

Will compression reduce my image's dimensions?

No - dimensions stay the same. Only the file size and stored detail change. Use Image Resize to change dimensions.

Which format gives the smallest file?

WebP usually produces the smallest file at a given quality, followed by JPG. PNG is best for graphics and transparency.

What quality should I choose?

80-85 is a good balance for photos. Go lower only if you need a very small file and can accept softer detail.

Is compression lossless?

JPG and quality-based WebP are lossy. PNG compression is lossless but produces larger files for photos.

Can I compress transparent images?

Yes - keep PNG or WebP as the output to preserve transparency; JPG will fill transparent areas with a solid color.
