How to Reduce Image Size kb/mb? follow these 4 simple steps

  1. Select Images

    Drag and drop your JPG, PNG, or HEIC files into the dropzone. Use our <a href="/tools/bulk-image-resizer"><b>Bulk image resizer</b></a> tool to process up to 50 images at once if you have many files.

  2. Set Your Target Size

    Choose whether you want to reduce the size by a percentage (e.g., 50% smaller) or target a specific file size (e.g., "Under 100KB").

  3. Adjust Dimensions (Optional)

    Sometimes the easiest way to drop from MB to KB is to resize the width. A 4000px image is rarely necessary for the web; 1200px is usually plenty.

Frequently Asked Questions

Can I reduce a 5MB image to exactly 50KB?

Yes, but it usually requires a combination of resizing (reducing pixels) and lossy compression. For the best results, convert the file to WebP during the process.

Will my image look blurry after compression?

Our tool uses "smart compression" algorithms. We analyze the colors and textures to ensure that the human eye cannot detect the difference, even when the file size is reduced by 70%.

Is it safe to process my private photos?

Yes. Image York is 100% safe because your photos are never uploaded to a server. All image processing happens locally in your web browser, meaning your files never leave your device.

Can I use Image York while offline?

Yes. Because our tools run on client-side JavaScript, once the website is loaded in your browser, you can continue to compress or edit images even if you lose your internet connection.
