May 16, 2025

Having images on your device means having a lot of files. Even more so, when they are in the JPG format as they ease compatibility and the quality/size ratio is acceptable. However, when trying to manage high resolution images, storage space may become an issue. One way to solve this problem is to change JPGs into the PDF format.

Advice for Optimizing Storage Space While Compressing Files

Tips: The step of converting JPGs to PDFs is already an optimization. However, there are additional tips that may further enhance your storage.

  • Resize Images Before Conversion: It is always preferable to use a photo editor that can resize (downscale) images, especially when ultra high resolutions are not a necessity.
  • Batch Process Images: Place all related images into a single PDF. This way you eliminate an excess amount of files whilst also retaining space.
  • Choose Compression Settings Wisely: It is known that large compressions tend to reduce the file size, but also lower the quality of the image. Therefore, identify what would work best for you.
  • Use Greyscale or Black & White: If the colors are not important in the image, changing the setting to greyscale can significantly reduce the overall file size.
  • Delete Metadata: Extras like GPS data and even metadata about the images which include time stamps or even the camera which took the photo add unwanted bloated data. These images also need tools that stride away irrelvant data during conversion.
