Online Image Compressor

How to Use the Image Compressor

Compress Images in Just a Few Clicks

1. Choose Compression Options (Optional)

   Before uploading, you can set the maximum size and the maximum image width or height to customize the compression process according to your needs.

2. Upload and Compress Images

   Simply drag and drop your images into the designated area or click to browse and select files from your device. The tool will automatically compress the images based on your chosen settings.

3. Automatic Download

   Once the compression process is complete, the optimized images will be automatically downloaded to your device, saving you time and effort.

• JPEG (Joint Photographic Experts Group)

  JPEG is a go-to format for digital photos, as it compresses images by reducing similar colors and patterns without losing too much detail. Its compression method uses discrete cosine transform (DCT), which represents image data as a sum of frequency components. This method eliminates high-frequency components with minimal visual impact, achieving a smaller file size while maintaining acceptable image quality. However, excessive compression might introduce visible artifacts or blurriness.

• PNG (Portable Network Graphics)

  PNG is a lossless format that uses the DEFLATE compression algorithm, which combines the LZ77 algorithm and Huffman coding. This method identifies and reduces repeating patterns and colors within the image without losing any data. As a result, PNG files maintain their original quality, making them suitable for images requiring sharp edges and transparency, like logos and icons. Though PNG files can be larger than JPEGs, they're ideal when image fidelity is crucial.

• WebP (Web Picture)

  WebP, developed by Google, combines the best of JPEG and PNG, offering both lossless and lossy compression. It uses advanced techniques like predictive coding and context modeling to achieve higher compression ratios. For lossless compression, WebP employs the LZ77 algorithm and Huffman coding, similar to PNG. For lossy compression, it uses a technique based on block prediction and a transformation similar to DCT, like JPEG. WebP's flexible compression methods result in smaller file sizes without significantly impacting image quality.

• BMP (Bitmap)

  BMP is an uncompressed format that stores image data as a grid of pixels, where each pixel contains information about its color and intensity. Since there's no compression, BMP files can be quite large, but they maintain their original quality. While BMPs aren't suitable for web use or situations where storage space is limited, they're ideal for image manipulation or editing that requires lossless quality.
