Image Optimization Tips
- For photos: Use JPEG with 75-85% quality. This typically reduces file size by 60-80% with minimal visible quality loss.
- For graphics/logos: Use PNG for images with transparency or sharp edges. PNG compression is lossless.
- For web: Consider WebP format - it often achieves 25-35% smaller file sizes than JPEG at similar quality.
- Batch resize: Use the resize presets in batch mode to create thumbnails, social media images, or optimized web images efficiently.
- Privacy: Enable "Remove EXIF data" in Advanced mode to strip location and camera metadata before sharing photos online.
What is Image Compression?
Image compression reduces the file size of images by removing redundant data or using more efficient encoding. There are two main types:
- Lossy compression (JPEG, WebP) - Reduces file size by discarding some image data. Higher compression = smaller file but lower quality.
- Lossless compression (PNG) - Reduces file size without any quality loss by using more efficient data encoding.
Smaller images load faster, use less bandwidth, and improve your website's performance. This is especially important for mobile users and SEO rankings.
Frequently Asked Questions
Yes, this image compressor is completely free to use. There are no limits on the number of images you can compress, no watermarks, and no signup required. All features including batch processing, format conversion, and ZIP download are available at no cost.
Absolutely. All image compression happens entirely in your browser using JavaScript. No images are ever uploaded to our servers - your photos and images never leave your device. This makes it completely safe to compress sensitive or personal images.
The compressor supports JPEG (JPG), PNG, and WebP formats. In Advanced mode, you can also convert between these formats - for example, convert a PNG to WebP for better compression while maintaining quality, or convert WebP to JPEG for broader compatibility.
In Batch mode, you can compress up to 20 images at once. Each image is processed individually with progress indicators, and you can download them all as a single ZIP file or download each image separately.
For photos and general web use, 75-85% quality provides an excellent balance between file size and visual quality - typically reducing file size by 60-80% with minimal visible difference. For images that need to stay crisp (like screenshots or graphics), use 85-95%. For maximum compression where some quality loss is acceptable, try 60-70%.
JPEG and WebP use lossy compression, meaning some data is discarded to achieve smaller file sizes. However, at 75-85% quality, the difference is usually imperceptible to the human eye. PNG compression is lossless - the visual quality remains identical, only the file encoding is optimized for smaller size.
Yes! In Batch mode, you can resize images using preset sizes (thumbnail 150px, small 300px, medium 800px, large 1920px) or enter custom dimensions. The aspect ratio is automatically preserved to prevent distortion.
WebP is a modern image format developed by Google that typically achieves 25-35% smaller file sizes compared to JPEG at equivalent quality. It's supported by all modern browsers. Use WebP for web images when file size is a priority. For maximum compatibility (email, older software), stick with JPEG or PNG.
