Online PNG Editor: A Guide to Using the Internet for PNG Editing


Photography originated as a way to capture the moment, but with recent technological advances in photo editing, a photograph is simply the starting point for an artistic endeavor. The prospects aren't limited to pictures you take with your camera. Digitally generated images are just as versatile with the multitude of tools the internet provides. Out of the many options for image features such as transparency and animation, different image formats have developed for optimal storage, and PNGs have become a very popular format for websites and graphic design.

What is a PNG?

When a text file is stored, your computer knows that its contents are limited to a preset collection of characters. These vary from language to language, but there is a finite number of shapes that can be considered text. With image files, there is no such guarantee, so storage is more complicated. Images come in many different formats, depending on whether they are static or animated. The most common image formats are

  • GIF - Graphics Interchange Format. The pronunciation debate rages on despite the creator telling us it's said with a soft G.
  • PNG - Portable Network Graphics.
  • JPEG - Joint Photographic Experts Groups.
  • BMP - Bitmap Image File. Developed for Windows, so alternate formats are recommended.
  • TIFF - Tagged Image File Format.
  • EPS - Encapsulated PostScript. Intended for use in vector applications, such as CorelDRAW.

If you are creating images, you are limited to the formats available for export in your editor, but within that subset, you can select whichever format best suits your needs for animation, file size, transparency, and color variation.

PNGs in particular have become popular for several reasons.

  • Accessibility - You don't need a copyright license or additional software on your device to open a PNG file. The GIF, however, is a patented format.
  • Transparency - Images with transparent backgrounds have a wider variety of uses in graphic design than those with opaque backgrounds. PNGs also allow for partial transparency, where GIFs require pixels to be fully opaque or transparent.
  • Color options - PNGs were created to replace GIFs. They can use up to 16 million colors compared to the GIF's 256.
  • Lossless compression - PNGs do not lose any of their quality when they are compressed. Unfortunately, this can lead to some large file sizes.
  • Animation - Like GIFs, the PNG can be turned into animated images, stored as APNGs.

How to find an online PNG editor

There are several online image editors available for free, though some of them offer additional features at their premium tiers. With an online PNG editor, you can do things as simple as cropping, shading, or resizing your image, or you could use some of the more advanced features to add or remove entire sections from your image. If photo editing software isn't in your budget, an online editor may give you the same functionality for free or at a fraction of the price.

You aren't limited to editing existing files - several of these tools allow you to make your own images from a blank canvas, even giving you the option of using layers to mimic the desktop editing experience. Some of them also offer watermarking capabilities so you can protect your intellectual property from digital art thieves. If a PNG isn't the best format for your project, you can also find tools to help you convert your image to a different format.
