The Right Way to Resize PNG

When it comes to changing pixel dimensions of your PNGs, our app can be a great helper. It will make the entire resizing process much easier and more convenient. All your graphics, logos, screenshots and other kinds of images can look crisp and clear, but only if resizing PNG is done correctly.

You should avoid downsizing or upscaling an image excessively – this will inevitably lead to the degradation of image quality. Never neglect the aspect ratio, otherwise your image will get stretched, squished or distorted in some other way. In other words, either your new pixel dimensions should match the original aspect ratio, or the aspect ratio needs to be changed to match the new pixel dimensions. Keeping both of these things in mind will help you get amazing-looking images. Plus, Watermarkly’s PNG resizer will do its best to maintain high image quality.

How to use Watermarkly’s PNG Resizer

  1. Go to > Tools > Resize Photos
  2. Click on “Select images” or drag the files into the editor. You don’t have to work solely with PNGs – it’s perfectly possible to import images of various formats, if necessary. Watermarkly’s app allows you to resize JPGs as well as GIFs.
  3. Pick how you want to resize PNGs – by entering new pixel dimensions or a specific number of percent. Type in new values. resize png
  4. There are some additional options that you can make use of. Pick any of them if needed. Our app can generate new pixels around the image, add white pixels, crop image, convert PNG to JPEG or convert to WEBP, keep metadata, blur faces or blur license plates.
  5. Tell the app to process your images by clicking on the “Resize Images” button.

Your resized PNGs can be saved to your device or imported to Google Photos or Dropbox.

Do you want to know how resizing PNG affects image quality? Let’s take a look at these examples!

Example #1. Here’s the original PNG image that has the size of 711 x 720 px.

resize png - example 1

And this is the resized PNG to 300 x 304 px.

resize png - example 1

As you can see, Watermarkly’s PNG resizer maintained excellent quality. There’s no distortion because new pixel dimensions match the original aspect ratio.

Example #2. Original logo with the size 200 x 200 px.

resize png - example 2

The logo’s pixel dimensions after resizing PNG : 400 x 400 px.

This example clearly demonstrates another advantage of our PNG resizer. The lines in the resized PNG look sharper and clearer than in the original. Usually, when you make an image bigger, it can get quite blurry and pixelated. But with Watermarkly, you’ll get a different result. You see, our resizer adds pixels and sharpens the lines when you upscale an image. Thus, your resized PNG will look crisp and neat.

Example #3. Original PNG file with transparent background: 348 x 348 px.

resize png - example 3

The same logo downsized to 200 x 200 px. The transparency has been preserved.

Example #4. Portrait PNG image with original size 480 x 720 px.

This is the resized version. Here you can see that it’s possible to resize PNG as well as change its aspect ratio by generating new pixels. And just like that a vertical picture was turned into a horizontal one!

When PNG Can Be Suitable for Your Images

It might be a good idea to opt for saving your images in PNG in the following cases:

  • Sharp lines and text: PNG can handle thin and thick lines, rough edges and solid colors quite well. It’s an ideal choice for text-heavy images even if you have a scan with lots of handwritten text. In a PNG image every letter will look sharp and clear. That’s why this format is great for logos, screenshots, infographics, illustrations and basically any image that contains a lot of text, various shapes and sharp lines. Moreover, PNG uses lossless compression and thanks to this, image content will be clearly visible and perfectly readable even if you need to resize or compress PNGs.
  • Transparency: This format supports transparency, thus it’s possible for some areas of a PNG image to be semi- or fully transparent. Due to this, PNG is an ideal choice for logos and icons because they often need to have a transparent background. Thanks to the transparent background, your PNG logo will fit in anywhere. It can easily be used on a website, added to a PowerPoint presentation or overlayed on a photo, regardless of the content, color scheme or background.
  • Frequent editing: If you need to edit one and the same image several times, it’s better for it to be in the PNG format. Since PNG supports lossless compression, no data loss occurs, and any kind of editing will be non-destructive. You can edit or resize PNG however many times you want, its quality will stay the same. In comparison, if you edit a JPG image multiple times, its quality will get worse. That’s because JPG is a lossy format, so every time you edit and export a JPG image, some data is lost.
  • Fewer colors: PNG is a great fit for images with a limited color palette.

When You Should Resize PNG Files

Here are the reasons why you might need to resize PNG files or images of any other format:

  • Meeting the size requirements: It doesn’t matter if you want to post an image on a webpage, your blog or social media account, it’s of high importance for it to have the correct pixel dimensions. This can be achieved by resizing a PNG. Thanks to this, your image will look sharp, clear and professional. It won’t get awkwardly stretched or distorted. It won’t get all blurry and pixelated. And if you want to insert it into a blog post, it won’t overlap the textual content.
  • Device compatibility: Different devices have different screen sizes and resolution. If you want to post an image on a website, you’ll need to resize PNGs so that they look sharp and clear on any device, regardless of whether they are viewed on a big screen of a desktop computer or a small screen of a smartphone.
  • Freeing some storage space: Because of all the perks that PNG has, a file in this format usually takes up more memory space than a JPG. If you make its image size smaller, its file size will decrease, too. This will make storing PNG images easier and more manageable especially if you have quite a lot of them.

Typically, if you change the size of a PNG, its quality won’t get worse. There’s an exception, of course. If you need to resize a PNG file of a large size to much smaller pixel dimensions, some loss of details and quality might occur.
