How to Reduce the File Size of an Image or Picture on Android

There are several ways to reduce the file size of an image or picture on Android. 

  • First, you can change the resolution of the photo before saving it. This will reduce the quality and detail of the image, but also its storage size. To do this from your camera app, tap ‘Settings’, then ‘Resolution’ and select a lower-resolution option (e.g. 2MP) for saving your images in future. 
  • Another way to reduce file size on Android is to compress images before you save them or upload them online. You can accomplish this with third-party apps, such as JPEG Optimizer and TinyPNG Compress & Resize Image that offer various compression settings depending on your requirements. Alternatively, you can use an online service, such as Compress Image to quickly and easily reduce the file size of your pictures without having to download any additional software. 
  • If you’d like to further reduce image file sizes but keep the same quality, consider using a lossless format, such as PNG instead of JPEG. This will give you smaller files that look just as good, but won’t take up so much space. To do this, save your images in PNG format rather than JPEG when given the option in your camera or photo editor app. 

These steps will help you effectively reduce the file size of images and pictures on Android while still keeping them looking great.

How to Reduce the File Size of an Image or Picture on Windows

Now that you have all of the prerequisites, it’s time to reduce your image or picture file size. There are a few different methods you can use depending on the type of file and your software. 

  • If you’re using Windows Photo Gallery, open the image in question. Then click “Organize” from the menu bar at the top of the window and select “Make a Copy” from the dropdown list. This will create an exact duplicate of your original photo but with a reduced quality level and/or resolution (depending on which settings you choose). You can also find this by going to File>Save As… for older versions of Windows Photo Gallery. 
  • Another option is to use a free online image resizer, such as This website will allow you to upload your picture and reduce the file size without losing any quality. All you need to do is select the “reduce file size” option and choose the desired resolution before downloading the new version of your image. 
  • Finally, if you have Adobe Photoshop installed on your computer, the process is even simpler. Just open up the image in question, go to File>Save for Web & Devices, then adjust the settings until you reach your desired file size. You can also try adjusting other options like sharpening or quality level if needed. 

No matter which method you decide to use, reducing an image or picture file size can be a quick and easy way to save space on your computer. With the right tools, you’ll be able to maintain the quality of your images while keeping the file size as small as possible. And remember: always make sure to back up your original photo before making any changes.
