Guide

Complete Guide: How to Compress Images

Reducing image file size is crucial for faster website loading, smaller email attachments, and efficient storage. Our tool uses smart compression algorithms to shrink images while preserving visual quality.

1

Capture or Upload Images

Choose files from storage or click 'Camera' to capture photos. Our mobile-optimized capture makes it easy to process physical documents or receipts on the fly.

2

Choose Compression Level

Select your preferred quality level: 'High Quality' (minimal compression, ~80-90% quality), 'Balanced' (good compression, ~70-80% quality), or 'Maximum' (smallest size, ~50-70% quality).

3

Preview File Size Reduction

See the estimated file size reduction for each image before downloading. This helps you decide if you need to adjust the compression level.

4

Download Compressed Images

Click 'Download' to save individual images or 'Download All' to get a ZIP file with all compressed images.

Pro Tips

  • For web images, 'Balanced' compression usually provides the best quality-to-size ratio.
  • Use 'High Quality' for images you plan to print or edit further.
  • Convert PNG to JPG before compressing for even better file size reduction (if transparency isn't needed).

Common Issues

Image quality looks poor?

Switch to 'High Quality' or 'Balanced' compression mode. Maximum compression is designed for web thumbnails and may reduce clarity.

File didn't compress much?

Images that are already optimized won't compress significantly. Try converting to a more efficient format (e.g., WebP) for better results.
