Tips on maintaining photo quality during resizing

Maintaining photo quality during resizing is crucial to ensure that your images continue to look sharp and visually appealing. Here are some tips to help you preserve image quality while resizing photos on an iPhone:

  • Use a High-Quality Resizing Tool

Choose a reliable resizing tool or app that is known for maintaining image quality during the resizing process. The built-in Photos app on the iPhone is a good option as it usually does a good job of preserving quality.

  • Aspect Ratio Consideration

When resizing, maintain the original aspect ratio of the image. This means that if you change the width, the height should change proportionally, and vice versa. Distorting the aspect ratio can lead to stretched or squished images.

  • Choose the Right Resolution

Pay attention to the resolution settings when resizing. Select a resolution that is appropriate for the intended use of the image. For example, lower resolutions are suitable for web sharing, while higher resolutions are better for printing.

  • JPEG Compression

If you’re saving your resized image as a JPEG file, be cautious with the compression level. Lower compression (higher quality) results in larger file sizes but better image quality. Higher compression (lower quality) reduces file size but can introduce artifacts and reduce image quality.

  • Avoid Repeated Resizing

Try to resize images only once or as few times as possible. Repeated resizing can lead to a cumulative loss of quality. If you need multiple versions of an image at different sizes, it’s best to resize from the original, high-resolution file each time.

  • Zoom In for Fine Adjustments

When fine-tuning the resizing process, consider zooming in on the image to closely inspect the details. This can help you ensure that the resized image maintains its sharpness and clarity.

  • Regularly Backup Originals

Before resizing any image, it’s a good practice to back up the original, high-resolution version. This way, you can always revert to the original if the resized image doesn’t meet your expectations.

  • Test with Sample Images

If you are resizing images for an important project, consider testing the resizing process with sample images first to gauge the results and make adjustments as necessary.

  • Use Dedicated Editing Apps

Dedicated photo editing apps, such as Adobe Lightroom or Snapseed, offer more advanced resizing and quality preservation options. These apps often provide greater control over the resizing process.


There are several powerful and user-friendly tools available on the App Store for resizing photos on iPhones, each catering to different user needs and preferences. These apps, including PicWish, Image Size, Pixlr, PicsArt, and InsFit, offer a range of features for precise resizing, aspect ratio preservation, batch resizing, compression options, and creative enhancements.
