Image compression reduces file size while preserving visual quality. This is essential for faster website loading, email attachments, and saving storage space. Our tool automatically compresses your images as soon as you upload them, showing you the size reduction instantly.
Click "Select Image" or drag and drop your image file into the upload area. Compression starts automatically upon upload.
Once compression is complete, you will see detailed statistics:
Click "Download" to save your compressed image. The file will be saved with the same format as the original.
Images are compressed immediately upon upload - no extra steps needed.
Algorithm optimizes compression to maintain visual quality while reducing size.
Works with JPG, PNG, WebP, and GIF images.
See exactly how much space you saved with detailed before/after comparison.
Compare original and compressed images side by side.
All compression happens in your browser. Images never leave your device.
Compression is lossy for JPG images - some quality loss may occur.
Very high compression may cause visible artifacts.
Keep your original file if you might need uncompressed quality later.
A: Results vary by image. Photos typically compress 40-70%. Already optimized images may only reduce 10-20%. Images with lots of solid colors often achieve higher compression.
A: Our algorithm balances size reduction with quality preservation. For most images, the difference is imperceptible. Very aggressive compression can cause visible artifacts.
A: JPG achieves the highest compression for photographs. PNG is better for graphics with solid colors. WebP offers good compression for both types.
A: Currently, images are processed one at a time. Upload a new image after downloading the compressed version.
A: Some images are already optimized or contain content that does not compress well. Screenshots with text and gradients may not compress as much as photos.
