Resizing images: reasons why photos lose quality

It's not uncommon for images to lose quality during various processes. Understanding the reasons behind this degradation can help us prevent it and ensure that our visuals remain sharp and clear. In this article, we'll explore some common reasons why images lose quality.

  • Compression

One of the most prevalent causes of image quality loss is compression. When an image is compressed, data is removed or simplified to reduce file size. While compression is necessary for web optimization and reducing storage space, excessive compression can result in noticeable loss of detail and sharpness. JPEG files, for instance, are prone to compression artifacts when saved with high compression ratios.

  • Resizing without proper techniques

Resizing an image without using the right techniques can lead to quality degradation. Enlarging a small image often causes pixelation, making it appear blurry or jagged. When you shrink an image it can also result in loss of detail if not done correctly, as some software may use algorithms that sacrifice quality for speed.

  • Wrong file format

Choosing the wrong file format can impact image quality. For example, using a lossy format like JPEG for images with transparency or sharp edges can lead to artifacts and a decrease in quality. It's crucial to select the appropriate format based on the content and intended use of the image.

  • Inadequate source material

Starting with a low-quality source image can limit your ability to maintain image quality. If the original photo or graphic is blurry, noisy, or has a low resolution, attempts to enhance or resize it may exacerbate these issues rather than improving the quality.

  • Overprocessing

Overprocessing an image with excessive filters, adjustments, or edits can result in quality loss. Each edit introduces the potential for artifacts, color shifts, and loss of detail. To preserve quality, it's advisable to make non-destructive edits and use high-resolution source files.

  • Multiple saves

Repeatedly saving an image in a lossy format like JPEG can compound quality loss over time. Each save may introduce additional compression artifacts. To mitigate this, consider working with lossless formats like PNG or TIFF for editing and only save the final version in a lossy format if necessary.

  • Improper color management

Incorrect color profiles or mismatched color spaces can lead to color shifts and loss of image quality, especially when printing. Ensure that your image editing software is set to the correct color profile and that you are working with consistent color management practices.

  • Low bit depth

Images with a low bit depth may exhibit banding, especially in gradients and subtle color transitions. Increasing the bit depth can help preserve image quality by providing more color information.

Understanding the reasons behind image quality loss is crucial for maintaining the visual integrity of your pictures and graphics. By avoiding excessive compression, using proper resizing techniques, choosing the right file formats, starting with high-quality source material, and practicing careful editing, you can minimize the loss of image quality and ensure that your visuals remain crisp and vibrant.

Why it’s important to keep quality when resizing your images

The importance of maintaining image quality during resizing cannot be overstated. Let's explore why it's crucial to keep the quality intact when resizing your images.

  • Visual appeal

The most apparent reason for preserving image quality is visual appeal. A high-quality image is pleasing to the eye, displaying sharp details, vibrant colors, and smooth transitions. When images lose quality during resizing, they can become blurry, pixelated, or distorted, detracting from their visual impact.

  • Professionalism

In professional settings, maintaining image quality is essential. Whether you're designing a website, creating marketing materials, or producing content for a client, the quality of your visuals reflects your professionalism. A low-quality, resized logo can convey a lack of attention to detail and expertise.

  • Brand image

For businesses and brands, consistency in image quality is crucial for brand identity. Distorted or poor-quality visuals can undermine brand credibility and erode trust. A cohesive and high-quality visual presence helps establish a strong and reputable brand image.

  • Printed materials

When resizing images for print, maintaining quality is paramount. Low-quality prints can result in images that look grainy or have visible artifacts. For marketing collateral, brochures, posters, and more, high-resolution images are essential to ensure a polished and professional finish.

  • User experience

On websites and apps, image quality significantly impacts user experience. Slow-loading, pixelated images can frustrate users and drive them away. To provide a seamless and engaging online experience, it's crucial to optimize images for the web without sacrificing quality.

  • Photographic integrity

Photographers understand the importance of preserving image quality. For them, resizing images while maintaining quality is about preserving the integrity of their work. High-quality photographs capture fleeting moments, emotions, and details, and resizing should not compromise these aspects.

  • Accessibility

In some cases, resized images are used in educational materials or presentations. Maintaining image quality ensures that important details remain visible, making the content more accessible to the audience. This is particularly relevant in fields like education and research.

  • Future-proofing

As technology advances, larger and higher-resolution displays become more common. Images that are resized with quality preservation in mind are more likely to remain relevant and visually appealing in the future. This future-proofing ensures that your visuals will stand the test of time.

  • Efficiency

Efficient techniques that help keep quality can save time and resources. Repeatedly editing and replacing low-quality images can be time-consuming and counterproductive. Investing in quality resizing upfront streamlines your workflow and prevents the need for constant adjustments.

Ways to resize photo without losing quality

Here’s how to resize images without losing quality and maintain the sharpness and clarity.

  • Use dedicated software. Utilize image resizer without losing quality – like Adobe® Photoshop®, Movavi Photo Editor, or GIMP. These offer advanced resizing options and interpolation algorithms for quality preservation.
  • Vector graphics. Create or convert images to vector graphics when possible, as they're resolution-independent and can be scaled without loss.
  • Maintain aspect ratio. When resizing, always maintain the original aspect ratio to prevent distortion.
  • High-resolution source. Start with a high-resolution source image to provide a better foundation if you want to enlarge images without losing quality.
  • Lossless formats. Save images in formats like PNG or TIFF with no quality loss during resizing.
  • Batch processing. Use batch processing tools for resizing multiple images while ensuring consistency.
  • Upsampling techniques. When enlarging, explore upscaling techniques and interpolation methods like "bicubic" or "Lanczos" to minimize quality loss.

Upsampling vs. downsampling

Upsampling and downsampling are two distinct processes used to adjust the resolution or size of images, audio, or data in various applications. The choice between upsampling and downsampling depends on the specific goals and requirements of a given task. Let's explore both processes and when one might be considered "better" than the other.


  • Increase in resolution. Upsampling involves increasing the size or resolution of an image or data. It's often used to make an image larger or to enhance its quality by adding more pixels or data points.
  • Interpolation. When upsampling an image, interpolation techniques are employed to estimate the values of new pixels or data points. These techniques aim to preserve as much detail as possible while you scale up the image.
  • Zooming in. Upsampling is commonly used when you need to zoom in on an image without losing image quality. For example, in photography or medical imaging, you may want to magnify a portion of an image for closer examination.
  • Enhancing visuals. In graphic design, upsampling can help improve the quality of visuals for printing or digital displays, ensuring that the images remain sharp and clear.


  • Decrease in resolution. Downsampling, on the other hand, involves reducing the size or resolution of an image or data. It is often used to decrease file size, improve processing speed, or adapt content for specific devices or applications.
  • Decimation. During downsampling, data points or pixels are removed, which can result in a loss of detail. The challenge is to balance the reduction in size with the preservation of critical information.
  • Web optimization. For web developers and designers, downsampling is crucial to ensure faster loading times of web pages. Smaller images reduce the amount of data that needs to be transferred, improving the user experience.

The key is to implement these processes carefully, using appropriate techniques to minimize the loss of quality or detail, regardless of whether you are expanding or compressing your data or visuals.

Enlarging or making an image smaller without quality loss

Enlarging or reducing the size of an image without sacrificing quality can be a challenging task, as it often involves manipulating the pixel count and dimensions. However, there are some tips and techniques that can help you achieve this goal.

Tips for enlarging images without quality loss:

  • Use vector graphics. If possible, create or obtain vector graphics. Unlike raster images (e.g., JPEG, PNG), vector graphics are resolution-independent and can be scaled up infinitely without any loss of quality.
  • Upscale with interpolation. When enlarging a raster image, use advanced interpolation algorithms. These methods generate new pixels based on surrounding information, which can help maintain image quality.
  • Start with a high-resolution source. If you know you'll need to enlarge an image later, begin with the highest resolution version available. Starting with a high-quality source image provides a better foundation for enlarging without loss.
  • Consider image editing software. Professional image editing software like Adobe Photoshop provides options for upscaling images using advanced algorithms. Explore the "Image Size" or "Resample" options and experiment with different settings to find the best result.
  • Noise reduction. Enlarging an image can accentuate noise and artifacts. Apply noise reduction filters or tools to minimize unwanted visual disturbances during the upscaling process.

Tips to reduce image dimensions without quality loss:

  • Choose the right format. When you want to lower image size, consider using a lossless format like PNG or TIFF. These formats retain image quality better than lossy formats like JPEG.
  • Maintain aspect ratio. Always maintain the aspect ratio (width-to-height ratio) when reducing image size. This ensures that the image doesn't become distorted.
  • Crop instead of resizing. In some cases, cropping a portion of an image might be a better option than resizing. Cropping allows you to focus on a specific area without compromising image quality.
  • Use dedicated resampling tools. Some image editing software offers dedicated resampling or downsizing tools. These tools are optimized to decrease image size without losing quality. Explore these options in your preferred image editing software.
  • Save a copy. Before downsizing an image, save a copy of the original in its full resolution. This way, you can always return to the high-resolution version if needed.
  • Test and preview. Always preview the results of your image reduction before finalizing it. Zoom in to check for any loss of detail or artifacts.
  • Batch processing. When resizing multiple images, consider using batch processing tools in image editing software. These tools can help you maintain consistency in image quality across your project.

In both cases, remember that there may be limits to how much an image can be enlarged or reduced while still maintaining quality, as it depends on the initial resolution and the final dimensions required. It's essential to strike a balance between your desired output and the limitations of the source material. By following these tips and using appropriate software and techniques, you can significantly improve your ability to resize images without quality loss.


Resizing images without compromising their quality is a crucial skill in the digital era, whether you're a photographer, designer, or content creator.
