Compress Image

Why compress an image?

Large image files slow down web pages, fill up storage, and get blocked by the upload limits on forms, email, and chat apps. Compression strips out the wasted data and re-encodes the picture at a smaller size, so it loads faster and sends easily while still looking right to the eye. You can compress by quality, trading a little fine detail for a big drop in file size, or set an exact target in kilobytes or megabytes and let the tool get as close as it can without going over. JPG and WebP squeeze down the most, while PNG stays sharp for graphics and screenshots with flat colour. Add several images and compress them in one batch. Everything runs in your browser on the original file, so nothing is uploaded and your photos never leave your device. If you also need smaller pixel dimensions rather than a smaller file, resize the image instead.

How do I compress an image online for free?

Upload a JPG, PNG, or WebP, then shrink it by quality or to a target file size in KB or MB, and download the smaller image. It runs entirely in your browser, so your photos are never uploaded.

Frequently asked questions

How much smaller can the file get?
It depends on the image and how much quality you are willing to trade. Photos saved as JPG or WebP often drop by 60 to 90 percent, while graphics and screenshots compress less. Set a target size and the tool gets as close as it can without exceeding it.
Will compressing reduce the quality?
A little, if you push hard. JPG and WebP are lossy, so smaller files give up some fine detail, though a moderate setting is usually indistinguishable. PNG compression is lossless and keeps the image exact, but it shrinks less.
Which formats can I compress?
JPG, PNG, and WebP, plus HEIC photos from an iPhone (converted to JPG on the way in). Any format the browser cannot re-encode is saved as a JPG.
Can I compress an image to an exact size, like 100 KB?
Yes. Switch to a custom target in KB or MB and the tool compresses to land under it. There are also ready-made pages for the most common size requirements. Compress to 100 KB
Can I compress several images at once?
Yes. Add a batch and the tool compresses each one with the same settings, then you download them individually or as a ZIP.
Are my images uploaded to a server?
No. Compression happens entirely in your browser, so your images never leave your device, with no watermark and no signup.
