How To Resize An Image on Android

Android users are sometimes skeptical about resizing images on their devices. They wonder if the tools and features would be sufficient or not, or maybe they will have to download third-party apps to resize images. Worry not, because we are revealing all the ways to resize on your Android device. Your use case could vary from cropping a picture for social media to bulk resizing images for websites. We assure you that this guide will help you cover all your image-resizing needs on Android devices.

But why does image resizing matter so much?Because it helps to save storage space on your Android device, alter pixels and percentages of an image and transfer files quickly. During the process of image resizing, several shortcomings may pop up out of nowhere. Without further ado, let's start by understanding the common mistakes to avoid when resizing images on Android devices.

Part 1. Common Mistakes to Avoid When Resizing Images on Android

1. Not Locking the Aspect Ratio

Android devices have drag-and-adjust features to resize an image. Users sometimes tend to overlook the presence of aspect ratios ( 1:1, 4:3, 16:9). And saving the image without freezing the aspect ratio can lead to blurry and stretched images.

Now, how to avoid this mistake? It's simple. Try to use the built-in aspect ratio selection on your Android device. It will set the frame for your image according to your needs and make it ideal for social media posting as well.

2. Saving the Image in the Wrong Format

Imagine saving a PNG as your profile picture. That’s disastrous. It happens when you resize your image but do not save it in the right format. If you edit a PNG and save it as a JPEG, your image will have a solid white (or black) background that you won’t be able to get rid of. Or you may end up converting your JPG file to a BMP, and suddenly, the image size has touched the clouds.

What happens next? That’s why you should ensure that your resized image has the preferred file format. It will refrain from losing quality and maintain an optimum file size that is necessary for uploading everywhere.

3. Over-compressing the File

You want to reduce the image size and make it ideal for uploading. But along the way, you end up over-shrinking the file size, and thus, the pixels burn out, and the quality depletes like a drying well.

Been there? No worries. The simple solution for this mistake is to determine the pixel size beforehand so that you can maintain an ideal compression for the image. For example, the ideal pixel ratio for your image could be 100 x 100 DPI, but if your input goes below that number, your image quality would end up being depleted. Thus, you must always look for the preferred pixel range and enter it if you are looking to reduce the file size.

4. Guessing Instead of Checking the Output Size

Another common mistake when resizing images on Android is guessing the output size. Your required dimensions could be precise, but because you aren’t sure, you just guess a number and input it into the field. That’s where the struggle really starts. Now that you have guessed the output size, your image could end up being stretched, squashed, or flattened (Which you obviously did not want to happen).

So, the solution is to check the output size and dimensions that you want your resized image to have, and then start resizing it on your Android device.

5. Using the Wrong App for the Task

Now, resizing has numerous use cases. You might want to resize the file size, upscale the image, or crop unwanted elements in the image. All of that may not be possible in one single native app. What do you do then? Most people end up using the wrong app for the task. Their actual need could be to reduce the file size, but they end up cropping the image or compressing it. This model also sacrifices the quality of the image and does not give much in return.

Getting rid of this menace is not hard. You just need to use a tool that is versatile and supports every type of image resizing that you might need. For instance, UniConverter! This software runs on your desktop and helps resize images like a pro! The best part? You can use it for free.

Part 2. Resize Images on Android With Built-in Tool

Every Android smartphone or tablet has a Photos app. This application is native or built-in, so you can do basic image resizing without being reliant on third-party apps. Every Photos app has somewhat similar features. Let's understand how to use the Photos app step by step for resizing images:

1. Open the Photos App

Navigate to the Photos App on your Android device and open it. Tap on the image that you want to resize. The options to optimize or share this image would be available at the bottom of the screen.

2. Tap Edit and Explore the Options

When you tap ‘Edit’, you will find another pop-up with multiple options. You will be able to crop the image, set the aspect ratio, and use basic editing features such as sharpening, tone enhancement, and adding filters.

3. Choose Crop or Resize

If you are looking for an aspect ratio that already exists, you will find it in the Crop or Resize option. If not, you can manually drag the cropper to remove the unwanted elements in the picture.

4. Make the changes and tap “Save.”

As a final step, preview the final output after cropping the picture. If you are satisfied with the results, tap ‘Save,’ and the image will be saved to your Android device.

The Photos app generally has the ability to crop and set the aspect ratios of the images that you are working on. However, it might not be able to alter the file size or upscale or downscale the image. In that case, it is important to use third-party tools that support advanced resizing options.

Part 5. Tips for Resizing Images on Android

Not every app can have the feature that you specifically need. Hence, follow these tips when you are resizing images on Android devices. They will help you to complete your resizing task efficiently and avoid pitfalls along the way:

1. Bulk Resize Images to Save Time

The apps that you are currently using might not have a bulk resizing option. Resizing one picture at a time can drain tons of hours and seem hectic. But guess what, you can avoid this and save those hours.

You must always choose an application that has a bulk resizing option for saving time and storage. Like UniConverter! It has all the advanced image resizing options to deliver quality images in an instant.

2. Use Preset Sizes for Social Media

Your image resizing app may offer preset sizes specifically for social media. You can use that to resize your image and get the accurate aspect ratio for each image. Without the presets, you might end up creating inaccurate images.

3. Rename for Better Organization

Rename the original images for better categorisation. Images that look similar might sometimes create confusion. You can also create a separate folder for all your resized images to keep your files organized.

4. Preview Before Saving

Before you export your images, you need to preview the images and cross-check the new file size and resolutions. Some apps do not have preview options, so you must ensure if its there before starting the bulk resizing procedure.

5. Beware of Watermarks

Your resized images may have a watermark. That may happen when you use the free version of an application. To avoid this, use an application that does not force the watermark on your images, even if you are on the free plan.

Conclusion

Resizing images on Android is not difficult. You have the option to choose the built-in Photos app or use a third-party application from the Play Store to resize the images. However, it is important to remember that the built-in application may not have the pixel modification feature. It will limit you to resizing the aspect ratio, but won’t help you with image compression.

In such a case, it is advisable to use a third-party tool or use UniConverter on a desktop. It is a versatile tool that is used to resize images, videos, and audio files. Through its free version, anyone can resize their images and save storage.
