Free online photo size reducer tool to compress jpg & png files
MozJpeg jpeg optimizer - Build by Mozilla, used by Instagram & Facebook
The gold standard for JPEG compression. MozJPEG improves JPEG compression efficiency achieving higher visual quality and smaller file sizes at the same time.
Image compressor that can decrease image size upto 95%
Most compression algorithms are not intelligent enough to identify distortions of little subjective importance versus those objectionable to the user.
Imagecompressor.io uses best in class compression techniques to minimize perceivable artifacts, distortion & pixelation. Result is a state of the art photo size reducer & compressor.
JPG Optimizer & Compressor - how does it work?
MozJPEG is used to compress JPEG images.
MozJPEG or Mozilla JPEG Encoder Project, an open source library developed by mozilla. MozJPEG reduces file sizes of JPEG images while retaining quality and compatibility with the vast majority of the world's deployed decoders.
PNG Optimizer & Compressor - How does it work?
PNG images are shrinked or compressed by a technique called "Quantization". It reduces the number of distinct colors in the image, usually with the intention that the new image should be as visually similar as possible to the original image.
Libraries PNGQuant and ECT are used to compress PNG images.
PNGquant is a lossy PNG compressor that significantly reduces file sizes by converting images to a more efficient 8-bit PNG format with alpha channel (quantization) - often 60-80% smaller than 24/32-bit PNG files.
More Features
Compress a folder or directory
You can now upload a folder or directory with images. Click on the Folder button to select the folder to upload. All jpeg & png files will be optimized using selected compression level.
Multiple Compression Modes
Four compression levels - Normal, Good, High, Extreme. Higher the compression, lower the image quality. We recommended Good compression mode as it maintains a fine balance between image quality & compression.
