Why Use Batch Image Compression?
Compressing images one by one is time-consuming and inefficient when you have multiple files. Our batch image compressor allows you to process up to 100 images simultaneously, saving you valuable time while maintaining consistent quality across all files.
Perfect for:
- Website Optimization: Compress all images for a webpage or blog post at once
- Photo Albums: Reduce the size of entire photo collections for easier sharing

Frequently Asked Questions
How many images can I compress at once?
You can compress up to 100 images simultaneously. Unlike many competitors that limit you to 20 files or impose file size restrictions, CompressPixel lets you batch process large collections of images (up to 50MB per file) completely free.
Can I use different quality settings for each image?
Currently, the batch compressor applies the same quality setting to all images for consistency and speed. If you need different settings for specific images, you can use our single image compressor for individual file processing with custom settings.
How long does batch compression take?
Compression speed depends on the number of images, their file sizes, and your device's processing power. Most batches complete in under a minute. Since all processing happens in your browser using Web Workers, compression runs in parallel for maximum speed without blocking your browser.
Will my images be uploaded to a server?
No! All compression happens locally in your browser using client-side JavaScript. Your images never leave your device, ensuring complete privacy and security. This also means faster processing since there's no upload/download time.
What happens if some images fail to compress?
If an image fails during compression (due to corruption, unsupported format, or other issues), the batch process continues with the remaining images. Failed files are clearly marked in the results, and you can still download all successfully compressed images.
Is there a limit on how many batches I can compress?
No limits! You can compress as many batches as you need, completely free. There are no daily limits, no account required, and no premium features locked behind a paywall. CompressPixel is truly free for everyone.
