JPEG Optimizer

JPEG-Optimizer is a free online tool to bulk compress and reduce JPEG, PNG, and GIF image size, and convert them into other formats (GIF/PNG) for displaying on the web in forums or blogs, or for sharing on Instagram. Completely Free. 20 images at once.



Privacy: Files are NEVER sent to the server, and all processing is handled via your own browser. The image or any image related data is never stored.

Max Size: Maximum output size of the JPEGs in KB. Minimum is 1KB.

Max Width or Height: The uploaded JPEG image will be resized such that the larger of its height and width is reduced to the specified value. The other dimension will be scaled proportionally. For example, if you specify that the image size should be reduced to 100KB and the uploaded image has dimensions of 1280X720, it will be resized to 100X50. If the dimensions of the JPEG are 720X1280, it will be resized to 50X100.

  • The JPG compressor accepts these extensions - .jpg, .jpeg, .jfif, .pjpeg, .pjp
  • Set a value for Image quality. The default is 80%. The minimum value is 1 and the maximum value is 99. This value will decide the file size of the final image. A low value means low quality image.
  • Optional: Set a value for maximum size (in MB) for the compressed image. This value takes priority over the Image quality value.
  • Optional: If you would like to convert the final images, you can do so by selecting a format from the "Output Format" list.
  • Optional: If you would like to resize the compressed image, then enter the maximum width or height for your image. Note that these values are "maxmium", and the optimized image will be resized in the same proportion as the uploaded image.
  • Click on "Compress", and your images will start compressing one by one. You can see the progress below the form.
  • You can download these images at once in a ZIP file or can download them one by one.
