Free, Unlimited Image Compressor

Reduce your image's file size by as much as 90% using our free, unlimited tool.

Use our image compressor to reduce your PNG, JPG, GIF, or other image file and free up space on your hard drive, phone, or cloud storage service, with minimal impact on quality.


Quality controls how much the image is compressed and how much quality can be lost. 1 is the lowest quality and most compression.




How to Compress a PNG, JPG, GIF, or Other Image


  1. Click Upload Image and choose any image on your computer that is taking up too much space or that you wish to compress for any reason.

  2. Press Compress Image and wait a few moments for your image to compress. Depending on its size, it could take a few seconds.

  3. Once the image has compressed, save the image by either pressing "Download as ZIP" or by right-clicking the image and selecting Save As.
  4. We allow you to download images as ZIPs so that you can download multiple compressed images at once, and also because Zip compression may help to compress the file even further.

  5. Enjoy your compressed image! Or, compress some more! There's no limit to how many images you can compress.

  6. For more assistance, refer to our guides, tutorials, and troubleshooting page.


Frequently Asked Questions


  • What is image compression?

  • Image compression makes the file sizes of images smaller, while usually preserving as much of the original quality and resolution as possible. This makes it easier to share and store images on your hard drive or online cloud storage service.

    The processes and algorithms used for compression vary, but they usually work by recognizing patterns in your image's binary data and also by identifying and removing non-essential information. This data is then used to convert the image into a format that requires fewer bytes (1s and 0s) to be interpreted and displayed by computers and devices.


  • Why should I compress my images?

  • In addition to reducing the file size of your images, allowing you to store more on your device or cloud storage service such as pCloud, iCloud, Google Drive, or DropBox, compressed images load faster on web browsers. This improves the user experience for visitors and for search crawlers, which is important for things like SEO, and especially important for users accessing your site with low-speed mobile data. They will also send faster over text message or email.

    Other reasons to compress your images include situations where you may be using an outdated, low-storage media format such as Compact Disc (CD) or similar. If you're planning to store many images on a CD, USB flash drive, SD card, or similar mobile media storage format, compressing your photos first will allow you to fit as many as possible.


  • Is there a limit to how many images I can compress?

  • No, there is no limit to how many images you can compress using our tool. You can upload and compress as many images as you'd like, free of charge. Whether you have one image or one hundred images to compress, our tool can handle it. We want to make it as easy as possible for you to compress your images and reduce their file size.


  • What types of images can I compress?

  • Our image compression tool can compress PNG, JPG, JPEG, GIF, and other common image file types. If you have an image that is not one of these file types, you may need to convert it to a PNG, JPG, or GIF first before compressing it. You also can use our video to GIF converter to convert your video to a GIF first, and then compress it using this tool.


  • How much can I compress an image?

  • Our image compression tool allows you to set the quality level of the image, which determines how much the image is compressed. The quality level ranges from 1 to 10, with 1 being the lowest quality and most compression, and 10 being the highest quality and least compression. You can try different quality levels to find the right balance between image quality and file size.

    Note that if you upload a JPG or other optimized image format and select a Quality setting of 10, the image will not be compressed. This is because JPG images are already an optimized image format, and a setting of 10 on our compressor simply converts an image to JPG format and does limited other processing to it.


  • What happens to my image when I press Upload or Convert? Is it uploaded to a server somewhere?

  • No. Our conversion script runs entirely on JavaScript, which is a programming language that runs on your web browser using your computer's CPU. We use an Open Source library called compressor.js to power our tool.

    With ConvertSecure, your files never leave your computer and are seen by nobody other than you and whom you choose to share it with. In fact, our web host won't even let us allow users to upload files to our server.

    Most similar online image compressors upload your image to a database or data center and offload the processing to a large server. This is because some of them will then hold your image hostage, forcing you to sign up for an account or provide your email address in order to download your photos. Not with ConvertSecure.

    We take your privacy and security seriously, which is why we do not even attempt to store your data or files. As they say, the best solution to a problem is often the easiest.
