Compress without uploading
Large photos slow down websites, fill up cloud storage, and cause slow loading times. This tool re-encodes your image at a lower quality setting to significantly reduce file size, all inside your browser. No files are ever uploaded to any server - your images stay completely private.
JPG and WebP formats provide the best compression for photographs, while PNG works best for graphics with transparency or sharp lines. Adjust the quality slider to balance between file size reduction and image quality.
How It Works
The image compressor uses your browser's built-in canvas technology to re-encode your image. When you upload an image, it is read directly in your browser (not sent to any server). The tool then creates a compressed version at the quality level you specify. You can download the compressed file instantly.
Supported Formats
- JPG / JPEG: Best for photos and complex images with many colors. Excellent compression ratios.
- WebP: Modern format that provides smaller files than JPG with similar or better quality.
- PNG: Best for images with transparency or sharp text and graphics.
Why Compress Images?
- Faster Websites: Smaller images load faster, improving user experience and SEO rankings
- Save Storage: Reduce file sizes by 50-80% for photos
- Email Attachments: Stay within email size limits
- Social Media: Optimize images before uploading to platforms
- Backup Savings: Store more photos with less space
Tips for Best Results
- For photos, use JPG format with 70-85% quality for a good balance
- WebP typically produces 25-35% smaller files than JPG
- For images with text or sharp lines, PNG may provide better visual quality
- The original file is never modified - only a new compressed copy is created
- All processing happens client-side; no internet upload is required
