Best Free Online Image Compressor

Website loading speeds and bandwidth limits are heavily influenced by image file sizes. Large photos not only slow down your web pages but also consume massive amounts of storage space. Our Free Online Image Compressor is designed to reduce the size of your JPEG, PNG, and WebP files without causing noticeable degradation in image quality.

How to Compress Images to Target KB/MB?

  1. Click the Upload area or drag and drop your image files into the box. You can upload multiple files at once.
  2. Select an image from the thumbnail gallery to adjust its specific settings.
  3. Type an exact Target File Size (KB) or use the Compression Level slider. The tools sync automatically to give you perfect control.
  4. Click Compress Image. Use our interactive slider to compare the Before & After quality.
  5. Hit Download Image to save it, or click Download All (ZIP) if you processed multiple files.

Frequently Asked Questions

Does compressing an image reduce its quality?
Yes, "lossy" compression (like JPEG and WebP) removes some visual data to reduce file size. However, keeping the quality slider between 70% and 90% typically results in massive file size reductions with quality changes that are invisible to the naked human eye. Use our interactive Before/After slider to see for yourself!
Why do PNG files sometimes get larger when compressed?
PNG is a lossless format designed to preserve exact pixels. Standard browser compression engines struggle to reduce PNG file sizes without changing colors. To solve this, our tool intelligently scales down the physical dimensions (resolution) of PNG files to hit your Target KB. For better results without losing resolution, we highly recommend changing the Output Format to WebP or JPEG.
Are my images uploaded to the internet or stored on your servers?
No, absolutely not. Unlike many other online tools, our Image Compressor runs 100% locally inside your web browser. Your images never leave your device, ensuring complete privacy and maximum security.
Can I compress multiple images at once?
Yes! You can select dozens of images at once during upload. They will appear in a gallery strip. You can compress them individually or use the "Apply & Compress All" button to batch process them using your chosen settings. You can then download them all in a single ZIP file.
Which output format is best for websites?
WebP is generally the best format for modern websites because it offers superior compression rates compared to JPEG and PNG, maintaining high quality at incredibly small file sizes. If you need maximum compatibility with older software, stick to JPEG. Use PNG only if your image requires a transparent background.
