In today’s digital age, the ability to manipulate images on your smartphone is not just a luxury; it’s a necessity. Whether you’re prepping files for social media, sending pictures via email, or simply saving space on your device, knowing how to change picture size on your Samsung S20 can streamline your digital life. This comprehensive guide will not only educate you on resizing images but also provide context on why it matters.
Understanding Image Size and Dimensions
Before delving into the step-by-step process of resizing images on your Samsung S20, it’s crucial to understand what image size and dimensions entail.
Image Size Vs. Dimensions
Image Size refers to the file size of an image, usually measured in kilobytes (KB) or megabytes (MB). This size impacts how quickly you can upload, download, or share photos.
Dimensions refer to the physical width and height of an image, commonly measured in pixels (e.g., 1920×1080). Larger dimensions may mean more detail, but also a larger file size.
Why Resizing is Important
- Space Management: Resizing images can free up storage on your device, allowing you to save more important files.
- Faster Sharing: Smaller images can be shared more swiftly via email or social media, enhancing your communication speed.
- Photo Quality: Sometimes lowering the resolution can improve the overall quality when uploading to specific platforms, aligning with their size limitations.
Preliminary Steps Before Resizing
Before resizing pictures on your Samsung S20, it’s essential to prepare your images. Here’s what you need to do:
Backing Up Your Images
Always ensure that your original images are backed up. You could use Samsung Cloud, Google Photos, or any external storage to keep your source files.
Identifying the Images to Resize
Browse through your gallery and identify the images that either require resizing or will be shared on platforms with strict size limits.
How to Change Picture Size on Samsung S20
There are several approaches to resize images on your Samsung S20, depending on whether you want to use the built-in tools or a third-party application. Let’s explore each method in detail.
Using the Built-in Gallery App
Samsung S20 comes equipped with a functional Gallery app that allows basic image editing, including resizing.
Step-by-Step Guide
- Open the Gallery App: Locate and open the Gallery app on your Samsung S20.
- Select the Image: Browse through your pictures and select the image you wish to resize.
- Tap on Edit: Look for the pencil icon at the bottom of the screen and tap on it to enter edit mode.
- Choose Resize Option: Once in edit mode, navigate to the crop icon. On most Samsung devices, this is usually located at the bottom.
- Adjust Size: When cropping, you can drag the corners or sides to resize to your desired dimensions. You also might see options showing specific aspect ratios.
- Save Your Changes: After adjusting the image size, click on “Save” to keep the resized image.
Note: The original image will still remain in your gallery unless you choose to overwrite it.
Using Third-Party Apps
While the built-in tools are handy, third-party applications can provide more control and options to resize your images on the Samsung S20.
Recommended Applications
-
Photo & Picture Resizer: This app is user-friendly and specifically designed for resizing images. It allows batch resizing and can quickly compress images.
-
PicsArt: Beyond resizing, PicsArt offers an extensive range of editing features, including custom aspect ratios, filters, and touch-up tools.
Step-by-Step Guide for Third-Party Apps
- Download and Install: Open the Google Play Store, search for “Photo & Picture Resizer” (or your chosen app), and install it.
- Open the App: Launch the app from your app drawer.
- Select Images: Navigate to the option where you can select images or a batch of images.
- Choose Resizing Options: The app will generally offer preset sizes and custom dimensions. Select your preferred option or enter specific width and height in pixels.
- Save the Resized Images: Review your changes and save the images to your gallery or external storage.
Tips for Effective Image Resizing
While resizing images can seem straightforward, adhering to best practices can make a significant difference:
Maintain Aspect Ratio
When resizing images, always maintain the aspect ratio (the proportional relationship between width and height) to prevent skewing and ensure that your images look natural.
Watch Out for Quality Loss
Excessive resizing can lead to quality loss. If you are decreasing the size, the loss may not be significantly noticeable. However, if you are increasing the size, images might become pixelated.
Consider File Format
The file format of an image plays a crucial role in its quality and size. JPEG is popular for photography due to its compression but may lose details. PNG is often better for graphics with text because it preserves clarity but tends to have larger file sizes.
Common Problems and Solutions
Lost Quality After Resizing
If you notice that your photos have lost quality after resizing, it is usually because of the format or the method used to resize. Make sure to resize images using applications that maintain quality.
Images Not Saving
If resized images are not saving correctly, try checking the app permissions in Settings to ensure the app has access to the storage.
Conclusion
Resizing pictures on your Samsung S20 can significantly enhance your experience by improving storage management and image quality across various sharing platforms. Whether you use the built-in tools in the Gallery app or opt for third-party applications, the ability to easily manipulate image size is within your reach.
Mastering these techniques not only bolsters your digital organization but also prepares you for a more seamless sharing experience. Take control of your image sizes today and enjoy a more efficient smartphone experience!
What are the steps to resize an image on Samsung S20?
To resize an image on your Samsung S20, first, open the Gallery app. Navigate to the image you want to resize and tap on it to open it. Then, look for the three-dot menu icon, usually located at the top right corner of the screen. Tap on it and select “Edit” from the drop-down menu.
In the editing interface, you will see various options. Tap on the crop tool which often allows you to adjust the dimensions of your image. You can drag the corners or edges of the crop box to get the desired size. Once you are satisfied with the new dimensions, make sure to save the edited image by tapping on “Save” or the equivalent option.
Can I resize multiple images at once on Samsung S20?
Unfortunately, the Samsung S20 Gallery app does not provide a native feature to resize multiple images simultaneously. However, there are third-party apps available on the Google Play Store that offer batch resizing capabilities. Apps like Photo & Picture Resizer or Bulk Resize Photo can be a great solution for this functionality.
To use these apps, simply download and install one of them from the Play Store. Then, follow the app’s instructions to select multiple images and specify the desired dimensions. Most apps will allow you to save the resized images back to your Gallery for easy access.
What is the best image format to use after resizing?
When you resize an image, the format you choose to save it in can impact both the quality and file size. JPEG is commonly used for photographs due to its balance of quality and compressibility, making it ideal for everyday use. PNG is another excellent option, especially if you need to maintain transparency or high quality.
If you plan to use resized images for online purposes, such as social media or websites, JPEG is often the preferred format due to its smaller file size, which helps with faster loading times. However, for images requiring detail and quality retention, like graphics or logos, saving as PNG might be the better choice.
Will resizing an image affect its quality?
Yes, resizing an image can affect its quality, particularly if you are enlarging the image. When you increase the size of a smaller image, it can appear pixelated or blurred because the software attempts to fill in the extra pixels. This process is known as interpolation, and it can lead to a loss of clarity and detail.
Conversely, reducing the size of an image generally maintains better quality since you’re discarding some pixel information. It’s crucial to start with a high-resolution image if you plan to resize downwards to preserve quality. Keep in mind that once you save the resized image, the original resolution will be lost, so consider making a copy before altering the size.
Is there a way to resize images without losing quality on Samsung S20?
While resizing often involves some compromise on quality, you can take steps to minimize loss. First, start with the highest resolution version of the image you have available. When using the Gallery app or a third-party image editor, try to resize to dimensions that are closer to the original size rather than making significant changes.
Additionally, consider using editing apps that have advanced algorithms for resizing images, which are designed to maintain quality. Popular choices include Adobe Photoshop Express and Snapseed, which provide options to save images with minimal loss in quality. Always check the final output before saving, and if possible, compare with the original to ensure you’re satisfied with the result.
How can I share a resized image directly from my Samsung S20?
After resizing an image on your Samsung S20, sharing it is straightforward. Once you have saved the resized image, go back to the Gallery app and find the resized photo. Tap to open it, and look for the share icon, usually depicted by three connected dots or a share arrow.
Select the share option, which will present you with various platforms and apps, such as social media, messaging, or email. Choose your desired method of sharing, and follow the prompts to complete the process. This allows for easy sharing of resized images without the need for transferring or additional steps.
Can I undo changes after resizing an image on Samsung S20?
Once you save a resized image in the Gallery app on your Samsung S20, the original dimensions of that image are replaced. Unfortunately, this means that if you want to revert to the original size, you may not be able to do so unless you had previously made a copy or have a backup of the image. Always be cautious when editing images, particularly if they hold sentimental or significant value.
To keep the original photo safe, consider using the “Save As” feature if available, which allows you to create a new copy of the image with your edits rather than overwriting the original. This way, you retain both the resized version and the original for future use without the risk of losing quality or detail.
