How to Convert an Image to PNG Format

The short answer

To convert an image to PNG, open the original file and export or save a copy in PNG format. You get a new file whose name ends in .png. The original stays as it is until you choose to replace it.

PNG, short for Portable Network Graphics, stores still-image pixels with lossless compression. The copy keeps the pixels you export, and it can store transparency (see-through areas). That is why PNG is a common choice for logos, graphics, screenshots, and edited photo backgrounds.

Before you convert

Have the source image on the device you will use, enough storage for a second file, and an app that can open that source and offer PNG as an export or save format. Typical sources include JPEG, HEIC, WebP, GIF, and BMP. This guide does not verify a named converter, so confirm that PNG appears in the app’s format list before you depend on it.

How to convert the image

• Open the original image in an image viewer or editor.
• Choose Save As, Export, or an equivalent command, and keep the original until you have checked the PNG.
• Select PNG as the format. Some editors label it PNG-24 or PNG-32; those names still produce a .png file.
• If you need see-through areas, leave transparency enabled. Choose an opaque background only when you want every pixel filled.
• Save the new file and note its name and folder.
• Open the PNG on its own and inspect framing, color, and detail.

How you will know it worked

• The new file’s name ends with .png.
• The image opens and shows the framing, colors, and detail you meant to keep.
• If you needed transparency, empty areas let another picture show through when you place the PNG on top of it. A checkerboard in the editor is a preview of those empty pixels; it is not part of the saved photo.
• The original file is still present and opens as before.

File size is a weak success check. A detailed photograph stored as PNG is often larger than the same picture stored as JPEG, because PNG keeps the pixel data instead of discarding it to shrink the file.

What conversion preserves

The PNG copy preserves the pixels you export, including any blur, noise, or compression already in the original. Saving a JPEG as PNG stops further JPEG-style loss from that point on; it does not reconstruct detail the JPEG already removed.

Use PNG when you need transparency, a graphic you will edit again, or a copy you can reopen without extra photographic compression. For a large photograph that will only be viewed as a photo, a photographic format such as JPEG often yields a much smaller file and an opaque image.

Using the PNG as a background

A physical background is the real scene or backdrop behind you. A virtual call background is an effect the call app applies to live video. An edited photo background is a still image whose empty or replaced areas were prepared in an editor. Export that still as PNG when you want those empty areas to stay transparent.

If the PNG is meant for a virtual-call background, convert it first, then open it in the call app and check that the app accepts the file and that the image fills the frame as you expect. Acceptance, cropping, and how the still is composited onto live video are properties of that app. This conversion creates only the still PNG file; it leaves camera access, live video capture, call quality, microphone detection, and whether speech is intelligible untested.

No input-level audio or video targets apply here. Maximum dimensions, color depth, and file-size limits belong to the app that will open the PNG next, and those limits are not specified in this guide. If a later step rejects the file, change the image size or follow that app’s own format rules, then export PNG again.
