How to Use Image Compressor
To compress images, drag and drop your image files onto the upload area or click to browse. You can upload multiple images at once. Each image is processed in your browser using canvas-based compression. Use the quality slider to balance file size reduction against image quality.
After compression, each image shows the original size, compressed size, and savings percentage. You can download individual compressed images or use Download All to save everything at once. This tool is ideal for reducing image file sizes before uploading to websites, blogs, or social media.
Frequently Asked Questions
What image formats can be compressed? expand_more
The tool supports JPG, PNG, and WebP images. Output is typically saved as JPG or WebP for the best compression ratios.
How much can image compression reduce file size? expand_more
JPG images can often be compressed by 50–80% with minimal visible quality loss. PNG compression varies more depending on image content. Photos compress more effectively than images with flat colours or text.
Does compression affect image dimensions? expand_more
No. This tool compresses image data quality without changing the pixel dimensions. Width and height remain the same; only the file size changes.
Are my images uploaded to a server? expand_more
No. All compression is performed locally in your browser using the HTML5 Canvas API. Your images never leave your device.
What quality setting should I use? expand_more
For web images where quality matters (photos, product images), 75–85% quality usually provides the best balance. For thumbnails or background images, 60–70% is often acceptable.
