Image Compressor
Compress JPEG and PNG images with adjustable quality
About Image Compressor
Image Compressor is a browser-based tool that reduces file sizes for JPEG and PNG images while maintaining visual quality. Whether you are optimizing images for web, email, or storage, this tool processes everything locally on your device with no uploads or server involvement.
Perfect for photographers, web developers, content creators, and anyone needing to shrink image files quickly. Adjust compression quality on a sliding scale to find the ideal balance between file size and image clarity for your specific needs.
How to use Image Compressor
Upload Your Images
Select one or multiple JPEG or PNG files from your device by clicking the upload area or dragging files directly.
Adjust Compression Settings
Use the quality slider to set your desired compression level and preview the results in real-time.
Download Compressed Files
Review the file size savings and download your optimized images individually or all at once.
Pro Tips
- Start with 75-80% quality for web images-most viewers will not notice quality loss while saving significant file size.
- Use 85-90% quality for images you'll print or display on high-resolution screens to maintain visual fidelity.
- Compress images before uploading to social media to avoid platform re-compression that can degrade quality further.
- Keep original files backed up before compression-lower quality settings are permanent once downloaded.
