Compress Images Online Without Losing Quality

Oversized images slow down websites, fill up phones, and hit upload limits on forms, email, and social platforms. This tool shrinks JPG, PNG, WebP, BMP, TIFF and GIF files while keeping them looking sharp — the same resolution, with far fewer bytes.

Everything happens on your device. Your images are decoded and re-encoded in the browser without touching a server, so nothing is uploaded and no copy of your files exists anywhere. Adjust the quality slider, pick an output format, and watch the before-and-after sizes before you download.

Need a different size first? Use the image resizer to change pixel dimensions, or the image converter to change the file format before you compress.

When you should compress images

Every website, online form, and CMS benefits from smaller images: pages load faster, uploads finish sooner, and storage lasts longer. Compress photos before posting them to social media, attaching them to email, or publishing them on a blog — the visual result is the same, but the file is a fraction of the size.

Choosing the right format and quality

JPG and WebP use adjustable quality, so the slider gives you direct control over the size-versus-detail trade-off — 85 is a safe default for photographs. PNG stays lossless, which suits screenshots, logos, and graphics with text where every pixel matters. Compare the before-and-after sizes shown for each file to dial in the right setting.

Private by design

Because every image is compressed in the browser, nothing is ever sent to us. That makes this tool a sensible choice for client work, product photos, unreleased designs, and anything else you would rather not share.
