The Compressor

Compress by format

How to compress an image online

1. Add up to 5 images to the box above.
2. Set the quality. 70 percent keeps photos looking good at a fraction of the size.
3. Optionally set a max width or height, such as 1920 px, to downscale huge photos.
4. Click Compress images and check the savings badge on each result.

Frequently asked questions

How much smaller will my images get?

Photos converted to WebP at 70 percent quality typically shrink by 60 to 90 percent. The exact savings show on every result.

Is the compression lossless?

No, it is lossy compression, which is what makes files dramatically smaller. At sensible quality settings the difference is hard to see.

What is the best setting for web images?

WebP at 70 to 80 percent quality with a max side of 1920 px covers most website needs.

Why did my PNG not get smaller?

PNG is lossless and ignores the quality slider. Choose WebP or JPEG output for real size reduction.

How do I compress an image to under 1 MB or even 100 KB?

Set the quality to around 70 percent and add a max width or height such as 1920 px, then check the size shown on the result. Still too big? Lower the quality or the max side and run it again; a 100 KB target usually means WebP at around 60 percent quality and 1280 px.

Does compressing images make my website faster?

Yes, noticeably. Images are usually the heaviest part of a page, so smaller files directly improve load time and Core Web Vitals, which Google uses as a ranking signal.

Will compressed photos still look good on social media?

Yes. Social platforms re-compress every upload anyway, so a sensibly compressed photo (70 to 80 percent quality) looks identical after upload while being much faster to post.
