If you want to resize photos quickly on your Android device, Photo & Picture Resizer is a great choice. This app allows you to easily reduce image size without losing quality. You don’t have to manually save resized pictures, because they are automatically saved in a separate folder for you.
Choose File > Reduce File Size (from the File menu at the top of the screen). Select the adjustments you want to make: Scale down large images: Images are scaled to the resolution used in the document while preserving visual quality.
The Photo Compress app available at Google Play does the same thing for Android users. Download the app and launch it. Select the photos to compress and adjust the size by choosing Resize Image. Be sure to keep the aspect ratio on so the resizing doesn’t distort the height or width of the photo.
Get Info panel
For any file or folder, you can quickly view its size by control-clicking it and selecting Get Info. In the top right of the Get Info panel, you’ll see its size. You can also highlight a file in Finder and use the keyboard shortcut Command-I to open the Get Info panel.
Right-click this folder, select “Send To” and choose “Compressed (zipped) Folder“. After doing so, a zip file of the folder containing your PDF files will appear. You have now successfully made PDF files smaller for uploads.
Remove unnecessary images, formatting and macros. Save the file as a recent Word version. Reduce the file size of the images before they are added to the document. If it is still too large, save the file as a PDF.

Width in pixels of the long side of the image, divided by inches of the long side of the print. So, a 4×6 is 200 DPI for this image because 1200 (long side of the image) divided by 6 (inches of long side of the print) = 200 DPI. A key piece of information to understand is that a digital image has no DPI, only pixels.
