When you compress a digital file, you remove bits of information in order to reduce its overall size. There are two types of compression: lossless, which reduces the file size without reducing quality, and lossy, which reduces the size and quality.

Because of the nature of JPEG files, only lossy compression is possible with these kinds of images. However, you can control how much compression the image receives to find a comfortable balance between file size and image quality.

JPEGs can get pretty big. A high-resolution photograph from an expensive camera, for example, could be huge. This will cause the photo to take up a lot of space on your hard drive. Compression, in this case, could be a useful tool to reduce the size of that photo so you don’t need to delete it.

JPEGs on smartphones, especially, are good candidates for compression. Most smartphone cameras output images in JPEG format. If you have a lot of high-quality photos on your phone’s internal storage, they could be taking up a lot of room. Compressing those files could be the difference between needing to delete/backup some photos or keeping them right where they are.

Our compression tool on this page is free, easy to use, and doesn’t require you to download any software. There are no watermarks, no registration is required, and you can use the tool as much as you like.

To start, upload your JPEG/JPG files by hitting the “Upload Files” button. If you like, you can drag and drop your files onto the “Drop Your Files Here” field instead.

Once uploaded, our tool will intelligently determine the ideal compression ratio for each image. You’ll see that ratio appear on its thumbnail in the queue. If you think an image should be more or less compressed than what our server determines, that’s OK — you can control it. Just tap the photo you wish to finely tune and use the quality slider to adjust to your preference. When you are satisfied, hit the “APPLY” button. Repeat these steps with all your uploaded images until you are sure they are good to go.

Once ready, hit the “DOWNLOAD ALL” button. You’ll get a ZIP archive filled with all your compressed JPEGs. If you don’t want a ZIP file, that’s OK, because you can download each image individually by hitting the “DOWNLOAD” button under its respective thumbnail.

If you have more images you’d like to compress, hit the “CLEAR QUEUE” button to start the process over again.

Yes, it is safe to upload and compress JPEG files using our online tool. There is no need to be worried about the safety of your original files because our server has no ability to delete them from your system. Any files you upload here will still remain on your computer or mobile device.

Additionally, our server is secure. It is fully automated so no one can see what you upload. Likewise, your uploaded information will be purged after 60 minutes, so your images remain private.
