How to Use the Image Compressor Tool
1. Upload your image by dragging and dropping it into the upload area or clicking to browse your files.
2. Adjust compression level using the slider:
- Higher values (80-100%): Better quality but larger file size
- Medium values (50-80%): Good balance between quality and file size
- Lower values (0-50%): Smaller file size but reduced quality
3. Choose output format based on your needs:
- Auto: Keeps the same format as the input image
- JPEG: Best for photographs and complex images with many colors
- PNG: Best for images with transparency or sharp edges
- WebP: Modern format with better compression and quality
4. Set maximum width (optional) to resize large images for additional file size reduction.
5. Click "Compress Image" to process your image.
6. Compare results between original and compressed images, then download the compressed version.
Frequently Asked Questions
How does image compression work?
Image compression works by reducing redundant image data and optimizing the file format. Our tool uses both lossless compression (which preserves all image data) and lossy compression (which removes some image data) depending on your settings and the image format.
Will compression affect image quality?
Yes, compression can affect image quality, especially at lower quality settings. However, our tool is designed to find the optimal balance between file size reduction and visual quality. At higher compression levels (80-100%), the difference is often imperceptible to the human eye.
What image formats are supported?
Our image compressor supports most common image formats including JPEG, PNG, GIF, BMP, and WebP. You can upload any of these formats and convert to JPEG, PNG, or WebP.
Is there a file size limit?
Yes, the maximum file size is 10MB. For larger files, you may need to use desktop software or compress in multiple steps.
Which format is best for compression?
WebP generally offers the best compression-to-quality ratio for most images. JPEG is excellent for photographs, while PNG is better for images with transparency or text. Our "Auto" option will try to determine the best format based on your image content.
Is my data secure?
Yes, all image processing happens directly in your browser. Your images are never uploaded to our servers, ensuring complete privacy and security.
Why should I compress images?
Compressed images load faster on websites, improving user experience and SEO rankings. They also take up less storage space, are easier to share via email or messaging apps, and consume less bandwidth on mobile devices.
