How to Convert WebP to PNG: The Complete Guide (Free & Lossless)

To convert WebP to PNG, open a free online converter such as FlashFile WebP to PNG, add your .webp images, click convert and download the PNG files. The conversion takes seconds, keeps transparency, and happens entirely in your browser — your images are never uploaded.

WebP is the modern image format Google created for the web, and most websites now serve their pictures as WebP. That is great for page speed, but it can be a headache when you save an image and then try to edit it, upload it to a form, or open it in an older app that only understands PNG and JPG.

This guide explains what a WebP file is, when PNG is the better choice, and every way to change WebP to PNG — online, in bulk, and with the built-in apps on Windows, Mac, iPhone and Android.

What Is a WebP File?

WebP is an image format developed by Google that can store pictures with either lossy or lossless compression. It also supports transparency (an alpha channel) and animation, which lets one format replace JPG, PNG and GIF on many websites.

According to Google’s WebP documentation, lossless WebP images are about 26% smaller than PNGs, and lossy WebP images are 25–34% smaller than comparable JPEGs. Smaller files mean faster pages, which is why browsers, CMS platforms and CDNs adopted WebP so widely.

The catch is compatibility outside the browser. Some image editors, office programs, printing services, upload forms and older operating systems still do not accept .webp files. Converting to PNG solves that instantly.

Why Convert WebP to PNG?

PNG is one of the most widely supported image formats in the world. Converting a WebP image to PNG is the right move when you need to:

• Edit the image in software that does not open WebP, or keep editing without adding compression artifacts.
• Keep a transparent background for logos, icons, stickers and product cutouts.
• Upload to a form or platform that only accepts PNG or JPG, such as some job portals, marketplaces and print shops.
• Archive a master copy in a lossless format that will open everywhere for years.
• Share with anyone without worrying about whether their device or app can display WebP.

WebP vs PNG: Key Differences

Both formats are excellent — they are simply built for different jobs. Here is how they compare:

In short: keep WebP for publishing on the web, and convert to PNG when you need maximum compatibility or a lossless file to edit. For a deeper look at PNG itself, read What Is PNG and JPG?

How to Convert WebP to PNG Online in 4 Steps

The fastest way to change WebP to PNG on any device is a browser-based converter. With FlashFile there is no account and no upload:

1. 1

   Open the WebP to PNG converter

   Go to the free FlashFile WebP to PNG converter. It works in any modern browser on Windows, Mac, Android, iPhone and Chromebook — nothing to install.

2. 2

   Add your WebP images

   Click Select files or drag and drop one or more .webp files into the box. You can add as many images as you like for batch conversion.

3. 3

   Click "Run WebP to PNG"

   Each image is decoded and re-saved as PNG directly on your device, usually in under a second per image. Your files are never uploaded to a server.

4. 4

   Download your PNG files

   Click each download button to save the new .png files. Transparent areas from the original WebP stay transparent in the PNG.

Because the conversion runs on your own device, it also works with private images — screenshots, ID scans or client work — that you would rather not send to an online server.

How to Batch Convert WebP to PNG

Saving a whole product gallery or a folder of downloaded images? Select all the WebP files at once (or drag the whole selection into the drop zone) in the WebP to PNG converter. Every file is converted in the same run, and you get a separate download for each PNG.

Tip: PNG files are larger than WebP. If you are converting many photos for email or upload, run the results through the Image Compressor afterwards, or convert to JPG instead with WebP to JPG.

How to Convert WebP to PNG on Windows, Mac and Mobile

If you prefer the apps already on your computer, these built-in methods work too:

Windows: Photos or Paint

1. Right-click the WebP file and choose Open with → Photos.
2. Click the … menu and select Save a copy (or Save as).
3. Change the file type to PNG and save.

You can also open the image in Paint and use File → Save as → PNG picture. Note that Paint does not keep transparency — transparent areas become white — so use Photos or an online converter for logos and cutouts.

Mac: Preview

1. Open the WebP image in Preview.
2. Choose File → Export.
3. Select PNG in the Format menu and click Save.

To convert several files, open them all in Preview, select every thumbnail in the sidebar with Cmd + A, then use File → Export Selected Images.

iPhone, iPad and Android

Phones rarely offer a built-in "save as PNG" option. The simplest method is to open flashfile.pro/tools/webp-to-png in Safari or Chrome, tap Select files, pick the image from Photos or Files, convert, and save the PNG to your device.

Which Method Should You Use?

Tips for Perfect WebP to PNG Conversions

1. Start from the largest version available. Converting cannot add resolution, so save the original-size WebP, not a thumbnail.
2. Use PNG for graphics, JPG for photos. If the image is a photo and you do not need transparency, JPG gives a much smaller file — see PNG vs JPG.
3. Check transparency after converting. Open the PNG on a dark background to confirm the edges look clean.
4. Remember animations become still images. An animated WebP turns into a single PNG frame.
5. Compress if size matters. The Image Compressor can shrink large PNGs for faster uploads.
