How to use

  1. Choose JPG, PNG or WebP images: drop them, pick them or paste one with Ctrl+V. Up to 30 at once.
  2. Pick a target size such as 200 KB, or switch to Quality to set the level yourself.
  3. Select Compress and drag the before/after slider to check the result.
  4. Download each image, or all of them in one ZIP file.

Examples

A job site asks for a photo under 200 KB

Choose your photo, pick 200 KB as the target and download. The result shows the final size, so you can check it is below 200 KB before you upload.

A large phone photo will not get under 100 KB

Turn on “Allow smaller dimensions if needed”. Very large photos often need fewer pixels as well as lower quality to reach small targets; the new width and height are shown with the result.

You want a lighter photo for email without a fixed limit

Leave the target on the suggested quality setting. Photos straight from a phone usually become much smaller with no visible difference on screen.

Limitations

  • Compression is lossy. Smaller targets remove more detail, so check the preview before you download.
  • A target is a maximum we aim for, not an exact size. When it can be reached, the result is usually a little below it. Very detailed images may stay above it when smaller dimensions are not allowed, and the result then says so.
  • PNG images with transparency are saved as WebP where your browser supports it, otherwise they stay PNG and may not reach small targets.
  • Re-encoding removes most embedded metadata such as camera details and location.
  • Images up to 20 MB and 24 megapixels each are supported, up to 30 images and 60 MB per batch.

Troubleshooting

The result is still above my target

Very detailed or very large photos may not fit a small target at an acceptable quality. Turn on Allow smaller dimensions, choose a larger target, or resize the image first.

The result is larger than the original

Your image is already well compressed. We keep the original in that case, so you never download a bigger file by accident.

My browser stopped responding

Very large images need a lot of memory. Close other tabs, or resize the image to smaller dimensions before compressing it.

Questions and answers

How do I compress an image to 200 KB?

Choose your image, select the 200 KB target and press Compress image. The tool searches for the highest quality that stays at or below 200 KB and shows you the actual result size.

Does compressing an image reduce its quality?

Yes, some detail is removed. At moderate targets the difference is often hard to see, but you should always compare the preview before downloading.

Is a KB 1000 or 1024 bytes here?

We use 1 KB = 1000 bytes, the same as most upload forms and operating systems such as macOS. The result size shown is measured from the real file.

Can I compress several images at once?

Yes. Choose or drop up to 30 images together. Each one is compressed with the same settings, you see how much each image shrank, and you can download them one by one or all together as a ZIP file.

How do I compress an image to 50 KB or 1 MB?

Choose 50 KB or 1 MB as the target size, or set any other size under Advanced options. For very small targets, keep Allow smaller dimensions turned on so large photos can reach the size with good quality.

Are my images uploaded?

No. Compression runs in your browser on your device. Your images are not sent to our servers for processing, and the ZIP file is also created on your device.
