Why Compress Images?

Faster Website Loading

Large images slow down your website, leading to higher bounce rates and lower conversions. Compressed images load faster, improving user experience.

Save Storage Space

Reduce the amount of storage space needed for your images, allowing you to store more files or reduce cloud storage costs.

Faster Email Sharing

Send images via email more quickly with smaller file sizes, avoiding attachment size limits.

Better SEO

Page speed is a ranking factor for search engines. Faster-loading pages with optimized images rank higher in search results.

Frequently Asked Questions

Will compression affect image quality?

Our tool uses compression which reduces file size by selectively discarding some image data. Higher compression levels will result in smaller files but may introduce visible artifacts. At lower compression levels (higher quality settings), the differences are usually imperceptible for most uses. You can adjust the compression level to find the right balance between file size and quality for your specific needs.

Is there a file size limit?

Since all processing happens in your browser, the file size limit depends on your device's memory. Most modern devices can handle images up to 20MB or more without issues.

Will I lose my original image?

No, your original image remains untouched. Our tool creates a new compressed version of your image, leaving the original intact. You can download the compressed version while keeping your original file.

Image Compression Tips

Optimizing images is crucial for website performance. Here are some tips to get the most out of our image compression tool:

1
Choose the right compression level

Higher compression reduces file size but may affect quality. For photographs, a compression level of 60-80% usually provides a good balance.

2
Resize before compressing

If your image is larger than needed, resize it first before compression for better results.

3
Use WebP when possible

If your target platforms support WebP, it generally provides better compression than JPEG or PNG.

4
Check the results

Always review your compressed images to ensure they meet your quality standards.
