Compress Image Online

Compressing images online has become an increasingly popular way to reduce file sizes for uploading and sharing photos and graphics on the web. With high resolution cameras and ever expanding storage needs, image compression tools provide a quick and easy way to shrink files without sacrificing too much visual quality.

Compressing images online can save a significant amount of storage space and optimize JPG, PNG, GIF and other common image formats. It also makes it faster and easier to upload and share photos online. For example, compressing a 10MB photo down to 1MB will allow it to upload 10x faster. This makes it especially beneficial for optimizing images for web pages, email attachments and social media posts.


What is Image Compressor?

An image compressor is a tool, program or online service that reduces the file size of digital image files like JPG, PNG, GIF and others. Image compressors work by eliminating redundant image data and optimizing the JPEG, PNG or other encoding in order to shrink the file size while maintaining as much image quality as possible.

There are several main techniques image compressors use:

  • Lossy compression - Some data loss is acceptable to achieve smaller file size. Used by JPEG and WebP formats.

  • Lossless compression - No data loss, but less effective size reduction. Used by PNG, GIF and SVG.

  • Chroma subsampling - Reduces color data bandwidth in JPEG images.

  • Quantization - Reduces precision of image data like DCT coefficients in JPEG.

  • Optimization - Efficient encoding, metadata removal and other optimizations.


How to Compress the Image Online?

Compressing images online is easy and can be done in just a few simple steps using free online tools. Here is a quick guide on how to compress images online:

  1. Upload your image file - Select your image. Our compressor accept JPG, PNG, GIF and other common formats. Simply select your image file and click upload.

  2. Adjust settings (optional) - Some compressors allow you to tweak the compression level by adjusting the quality/size slider. Lower quality = smaller file size. Higher = better quality but larger file.

  3. Download compressed image - Once uploaded, the compressor will process your image and provide a compressed version available for download. The whole process usually takes just seconds.

  4. Check file size and quality - Review the download image to ensure an acceptable file size reduction and image quality. Re-adjust settings and re-compress if needed.

  5. Save and use image - Save the compressed image file and use as needed for your website, emails, social media posts, etc. Enjoy reduced file sizes!

The process is very fast, easy and free. With most online compressors you can drag and drop your image and download an optimized version in under a minute

Compress JPG, PNG, SVG or GIF With the Best Quality and Compression

Here are some tips for getting the best compression and quality when optimizing JPG, PNG, SVG and GIF image formats:


  • Use quality setting between 60-80% for best balance of size and quality.

  • Enable chroma subsampling to reduce color data.

  • Use baseline/standard compression instead of progressive.

  • Remove EXIF metadata if not needed.

  • Use online compressors like TinyJPG for extra optimization.


  • Convert to PNG8 format instead of PNG24 using image converter when possible.

  • Use fewer colors like 256 or fewer.

  • Remove metadata chunks if unnecessary.

  • Use TinyPNG or other online compressor for best optimization.


  • Simplify paths by combining shapes and reducing nodes.

  • Remove any unnecessary filters or effects.

  • Clean up code formatting and spacing for smaller file size.

  • Optimize and compress with SVGO or other SVG optimization tools.


  • Use fewer colors like 256 or less.

  • Reduce frame rate if possible without impacting quality.

  • Crop animation and remove any whitespace.

  • Optimize with online tools like Ezgif Gif Compressor.

Finding the optimal compression and quality balance may require testing different settings. Online compressors provide a quick and easy way to experiment. But following these tips will get you the best results when compressing JPG, PNG, SVG and GIF files.
