About Image Compression

Compress images to reduce file size while maintaining quality:

  • Adjust quality slider to balance size vs quality
  • Choose output format (JPEG, PNG, WebP)
  • See before/after comparison and file size reduction
  • Quick presets for common compression levels

💡 Tip: WebP format offers best compression. Use 80% quality for good balance between size and quality.

What It Does

An Image Compress tool reduces image file size while preserving visual quality. It uses compression algorithms to remove unnecessary data from images, making them smaller for faster loading, easier sharing, and reduced storage requirements. You can adjust the compression level to balance between file size and quality - higher quality means larger files, lower quality means smaller files. The tool shows before/after file sizes and reduction percentages, allowing you to see the impact of compression. Perfect for optimizing images for websites, email attachments, social media, or storage. Supports JPG, PNG, and WebP formats, with different compression options for each format. All processing happens locally in your browser for privacy and speed.

Key Features:

  • Adjustable compression level (quality vs. file size)
  • Before/after file size comparison
  • File size reduction percentage display
  • Support for JPG, PNG, and WebP formats
  • Quality slider for fine-tuning compression
  • Visual preview of compressed image
  • Maintains image dimensions while reducing file size
  • Privacy-focused - all processing in browser

How To Use

Compressing images is straightforward: upload your image, adjust quality, and download the optimized result.

1

Upload Image

Upload your image file by clicking the upload area or dragging and dropping. The original file size will be displayed.

2

Adjust Compression Level

Use the quality/compression slider to adjust the balance between file size and image quality. Higher quality = larger file, lower quality = smaller file.

3

Preview Compressed Image

See a preview of the compressed image and compare it with the original. Check that quality is acceptable for your needs.

4

View File Size Reduction

See the new file size and reduction percentage. Typical reductions are 30-70% while maintaining good visual quality.

5

Download Optimized Image

Download the compressed image when satisfied with the quality/size balance. Use the optimized image for faster loading and sharing.

Pro Tips

  • •Start with medium quality and adjust based on results
  • •Photos can usually be compressed more than graphics with text
  • •WebP format offers best compression with good quality
  • •For web use, 70-80% quality is often sufficient
  • •Compare original and compressed side-by-side to judge quality
  • •Higher compression = smaller files but may show artifacts

Frequently Asked Questions

1 Will compression reduce image quality?
Compression does reduce quality to some degree, but modern compression algorithms are very good at maintaining visual quality while reducing file size. At moderate compression levels (70-80% quality), most people won't notice quality differences, but file size can be reduced by 50-70%. The tool lets you adjust the balance - you can choose higher quality (larger files) or lower quality (smaller files) based on your needs.
2 How much can I compress an image?
Compression depends on the image content and format. Photos can typically be compressed 50-70% with minimal quality loss. Images with lots of detail or text may need less compression. WebP format often provides 25-35% better compression than JPG at the same quality level. The tool shows you the file size reduction so you can see the impact.
3 What's the difference between JPG and PNG compression?
JPG uses lossy compression (some quality loss) and works best for photos. PNG uses lossless compression (no quality loss) but produces larger files, best for graphics with text or transparency. For compression, JPG can achieve much smaller file sizes than PNG. If you need transparency, use PNG or WebP. If file size is priority, use JPG or WebP.
4 Should I compress images before uploading to websites?
Yes! Compressing images before uploading improves website performance, reduces bandwidth costs, and provides better user experience. Many content management systems (WordPress, etc.) compress images automatically, but pre-compressing gives you more control over quality and ensures optimal file sizes from the start.
5 Can I compress images multiple times?
You can, but each compression adds more quality loss. It's better to compress once from the original high-quality image rather than compressing an already-compressed image. Always work from original images and compress to your target quality/size in one step for best results.
6 Is my image data kept private during compression?
Yes! All compression happens entirely in your browser. Your images are never uploaded to servers, transmitted over the internet, or stored anywhere. This ensures complete privacy and security, which is important for personal or sensitive images.
