FAQ
An image compression tool is an online utility that batch-compresses common images such as JPG, PNG and WebP, reducing file size while keeping quality as high as possible, ideal for web use, emailing and storage cleanup.
Three steps: Upload images → choose a Compression Level → click Start. When done, pack download or download files one by one.
Common browser-decodable formats such as JPG, PNG, WebP are supported, and the output keeps the same format.
At Light / Normal levels the difference is barely visible; Strong / Extreme shrink files a lot but may show blur or artifacts, so choose based on your needs.
A single image should ideally stay under a few tens of MB; larger, higher-resolution images need more browser memory and may process slowly or fail.
Processing happens locally in your browser with no upload, so speed mostly depends on the number and size of images and usually finishes within seconds, faster than server-based online tools.
Images are processed entirely in your browser and are never uploaded to any server, so you can use it with confidence and better privacy.
Completely free with no sign-up or login; open the page and use every feature.
Yes. Being web-based, it opens in the browsers of phones, tablets and computers alike, and the layout adapts automatically to screen size.
The online version is install-free and instant, takes no device space, and suits everyday lightweight compression; desktop software is more advanced but must be installed. For daily compression, prefer the online version.
Re-compressing an already heavily compressed or very small image can increase its size due to encoding overhead; in that case the tool keeps the original automatically instead of forcing a replacement.
Yes. Upload multiple images at once; they are processed with the selected Compression Level and can then be packed into a ZIP for download.
The tool offers multiple strength levels. Light / Normal levels are nearly lossless, letting you freely trade off between size and quality for different scenarios.
Choose Strong or Extreme for the smallest size; if that is still not enough, convert the image to WebP for a higher compression ratio.
