Image Compressor

No image selected yet.

An Image Compressor reduces the file size of a photo or graphic so it loads faster, uploads more easily, and takes less storage space. Large images from phones and cameras often slow down websites, fill up email inboxes, and fail to upload on forms with size limits. This free tool shrinks your image right here in your browser, so you can share it, post it, or store it without the extra weight.

Everything happens locally on your device. Your image is never sent to a server, never stored by us, and never shared with anyone else. The tool uses your browser to redraw the image and save it again at a lower quality or in a different format. That means it works quickly, respects your privacy, and can even be used for personal or sensitive pictures with confidence.

How to use

  1. Click the file box and choose an image from your phone or computer.
  2. Check the original size shown below the picker.
  3. Move the quality slider. Lower quality gives a smaller file, while higher quality keeps more detail.
  4. Choose JPEG for most photos, or PNG when you need transparency or sharper edges.
  5. Look at the preview and the new size, including the percentage saved.
  6. Adjust the slider again if you want a different balance of size and quality.
  7. Click the download button to save the compressed image to your device.

Frequently asked questions

Will compressing reduce image quality?

A little, depending on the setting you choose. At eighty percent quality, most people cannot see any difference in normal photos, yet the file is often much smaller. If you lower quality too far, you may notice softness or small blocks, so try a middle setting first and compare the preview before downloading.

Should I choose JPEG or PNG?

Choose JPEG for photographs and everyday sharing because it usually gives the smallest files. Choose PNG for logos, screenshots, text, or images with a transparent background. PNG files are often larger, and changing quality has less effect on them, because PNG uses a different, lossless method.

Is there a file size limit?

There is no fixed limit set by this tool, but very large images may take longer on older phones. Because processing is local, speed depends on your device. If an image fails, try closing other tabs or using a smaller copy first.

Are my images uploaded anywhere?

No. All processing is done locally in your browser. Your file stays on your device from start to finish.
