Image Compressor

Reduce image size to a target KB. Files stay on your device.

If you set a target size, quality is adjusted automatically, and the image is scaled down if needed. PNG files are converted to JPG or WebP, and transparent areas become white.

About this image compressor

Large photos are slow to upload and are often rejected by forms that allow only 50 KB, 100 KB or 200 KB files, which is common for exam applications, job portals and ID uploads. This tool re-encodes your image in the browser. With a target size, it searches for the highest quality that fits, and scales the image down if even the lowest quality is too big. Nothing is uploaded, so it is safe for personal photos and documents.

How to use it

  1. Add one or more images.
  2. Set a quality, or enter the target size in KB.
  3. Press Compress images and download each file or the ZIP.

Frequently asked questions

Why is the result sometimes larger than the target?

Very small targets may be impossible for large images. Add a max width to shrink the dimensions too.

Does it keep transparency?

No. Images are saved as JPG or WebP with a white background.
