Image Compressor: reduce image file size

Make JPG, PNG and WebP files smaller by adjusting quality, format and dimensions. Compression happens in your browser, so your image isn't uploaded anywhere.

This tool runs in your browser. Your image is compressed on your device and isn't uploaded to ClearCut or anywhere else.

The format affects how small the file can get. WebP is often the smallest. PNG is lossless and is usually the largest for photos.

Lower quality gives a smaller file but can show blocky areas or banding. Check the preview after compressing.

Making the image smaller often reduces the file size more than lowering the quality. Images are never enlarged.

How to compress an image

  1. Choose an image

    Drag a JPG, PNG or WebP file onto the tool, or pick one from your device. Your browser opens it locally.

  2. Adjust the settings

    Enter a target file size in KB or MB, or pick a quality level yourself. Choose whether to keep the format or switch to JPG or WebP, and optionally reduce the dimensions.

  3. Compare and download

    See the original and compressed versions side by side, along with both file sizes. Download the result if you're happy with it.

What to expect

How much smaller a file gets depends entirely on the image, so we don't promise a particular percentage.

  • Large photos from cameras and phones often shrink a lot, especially when you also reduce their dimensions for use on a website or in an email.
  • Images that are already compressed may only get a little smaller, and occasionally the result is larger. The tool shows the exact sizes, so you can simply keep your original.
  • PNG files are re-saved without quality loss when you keep them as PNG. The browser's PNG encoder is designed for correctness rather than the smallest possible file, so a re-saved PNG can come out larger. Saving as WebP usually makes a much bigger difference, and WebP keeps transparency.
  • JPG output fills transparent areas with white, because JPG doesn't support transparency.
  • Metadata such as camera details and location isn't copied to the compressed file.

Image Compressor FAQ

Is my image uploaded?

No. The Image Compressor processes your image in your browser, and the compressed file is created on your device. This is different from ClearCut's Background Remover, which uploads images to our servers for processing.

Which formats are supported?

You can compress JPG, PNG and WebP images. You can keep the original format or save the result as JPG or WebP. Saving as WebP needs a browser that can create WebP files.

Can I compress an image to a specific file size?

Yes, approximately. Enter a target such as 500 KB or 1 MB. For JPG and WebP, the tool tries a range of quality settings and keeps the result closest to your target. The final size can vary depending on the image, format and browser encoder, so it won't always be exact. PNG is lossless in the browser, so its size can't be tuned this way. If a target can't be reached, the tool tells you and shows the actual result. It never pads a file with meaningless data to make it bigger.

What quality setting should I use?

There's no single right answer, because it depends on the image. The default of 75% is a sensible starting point for photos. Compare the result with the original at the size it will actually be shown, and lower the quality until you start to notice a difference.

Why is my compressed image larger than the original?

Some images are already compressed very efficiently, and the browser's encoder can't improve on them at the settings you chose. This is most common with PNG files kept as PNG. Try a lower quality, WebP, or smaller dimensions, or keep your original file.

Does compression change the image dimensions?

Only if you choose a maximum size. Otherwise the width and height stay the same, and only the way the pixels are stored changes.

Is there a file size limit?

Yes. Files can be up to 25 MB and up to 16 megapixels. The work happens on your device, and some browsers, especially on phones, can't handle larger images.
