What is Image Compression?
Image compression reduces the file size of an image by removing redundant or less important data. Lossy compression (JPEG, WebP) discards some visual information for smaller files, while lossless compression (PNG) preserves every pixel. This browser-based tool uses the Canvas API for client-side compression, meaning your images are never uploaded to any server.
How to Compress Images
- Drag and drop an image or click to select a file (JPEG, PNG, WebP, BMP)
- Adjust the quality slider — lower values create smaller files
- Optionally enable resize to reduce dimensions
- Click Compress to process the image
- Download the compressed image or compare before/after sizes
Frequently Asked Questions
What image formats are supported?
This tool supports JPEG, PNG, WebP, and BMP input images. You can output to JPEG, PNG, or WebP format. JPEG and WebP offer the best compression ratios for photographs, while PNG is better for graphics with transparency.
How much can I reduce the file size?
Compression ratios vary by image content and quality setting. Photos typically achieve 60-80% size reduction at quality 80%. Graphics and screenshots may achieve 30-50% reduction. The tool shows the exact before/after sizes and savings percentage.
Does compression affect image quality?
At quality 80-90%, the visual difference is nearly imperceptible for most images. Below 60%, artifacts become visible, especially in areas with gradients or fine details. The preview lets you judge the quality before downloading.
Can I compress multiple images at once?
Yes. Use the Batch Compress tab to add multiple images and compress them all with the same quality settings. You can download each image individually or see the total savings summary.
Is my data safe?
Yes. This image compressor runs 100% in your browser using the Canvas API. No images are uploaded to any server. All processing happens locally on your device, ensuring complete privacy.
