WebP files are everywhere now. Google pushed the format hard, and most websites serve images in WebP to save bandwidth. The problem? Try opening one in older software, uploading it to a platform that doesn’t support WebP, or just sharing it with someone who has no idea what a .webp file even is. You need PNG.
I spent a week testing every WebP-to-PNG converter I could find. Online tools, desktop apps, command-line utilities, built-in OS features. Here’s what actually works well, what’s slow, and what tries to upsell you on every click. If you also need JPG output instead of PNG, check my guide on how to convert WebP to JPG free.

Why Convert WebP to PNG (and Not JPG)?
Quick version: PNG keeps transparency. If your WebP image has a transparent background, converting to JPG will fill it with white (or black, depending on the tool). PNG preserves the alpha channel perfectly.
PNG is also lossless. Every pixel stays exactly as it was. JPG compresses and throws away data you can’t get back. For screenshots, logos, graphics with text, or anything where you need pixel-perfect accuracy, PNG is the right target format.
The tradeoff? PNG files are bigger than JPG. A photo that’s 200 KB as WebP might be 1.5 MB as PNG. For photos where transparency doesn’t matter, JPG is the better choice.
1. CloudConvert – Best Overall
CloudConvert handles WebP to PNG conversion without any quality loss, and it preserves transparency perfectly. I tested it with 40+ images including some with complex semi-transparent edges, and every single one came out identical to the original.
How to use it:
- Go to CloudConvert’s WebP to PNG converter page
- Click “Select File” and upload your WebP image (or drag and drop)
- The output format should already be set to PNG
- Hit “Convert” and download when it’s done
Free tier gives you 25 conversions per day, and you can upload files up to 1 GB. That’s generous. The conversion is fast too – most images finished in under 3 seconds.
What I liked: Clean interface, no ads in your face, reliable transparency handling. You can also connect Google Drive or Dropbox to pull files directly.
What I didn’t: The 25/day limit can be annoying if you’re doing a big batch. Paid plans start at $8/month for 500 conversions.
2. FreeConvert – Best for Large Files
FreeConvert is solid for big WebP files. The 1 GB limit on the free tier is among the highest I found. Honestly, if your WebP file is over 100 MB, most other online tools will just reject it.
How to use it:
- Open FreeConvert’s image converter
- Upload your WebP file
- Select PNG as the output format
- Click “Convert” then download
You get 5 free conversions at a time. Speed was decent in my tests – a 15 MB WebP file converted in about 7 seconds. Transparency preserved correctly.
What I liked: High file size limit, straightforward process, no account required.
What I didn’t: There are ads, and the download page has a countdown timer that feels unnecessary. Also, only 25 free conversions per day.
3. Convertio – Quick and Simple
Convertio has been around forever and it works. The interface is clean, conversion is fast, and it supports basically every image format you can think of.
How to use it:
- Go to Convertio
- Upload your WebP file (drag and drop works)
- Choose PNG as output
- Click “Convert” and download
The free tier limits you to 100 MB files and 2 simultaneous conversions. For occasional use, that’s fine. I converted a batch of 12 WebP files (screenshots with transparency) and every one came out clean.
What I liked: Supports pulling files from Google Drive, Dropbox, and URLs. Fast conversion.
What I didn’t: 100 MB limit is tight for high-res images. The free tier caps at 10 minutes of conversion time per day, which sounds like a lot but adds up if you’re doing batches.
4. Ezgif – Best for Preview Before Download
Ezgif is known for GIF editing, but their image converter is surprisingly good. The killer feature? You can see the converted PNG right in the browser before downloading it. No other tool on this list does that as smoothly.
How to use it:
- Go to Ezgif’s WebP to PNG page
- Upload your WebP file or paste an image URL
- Click “Convert” and preview the result
- Download if it looks good
Max file size is 50 MB on the free tier. No batch conversion – it’s one file at a time. But for quick one-off conversions where you want to visually verify the output, it’s great.
What I liked: Preview feature, URL import support, no signup needed.
What I didn’t: Single file only, 50 MB cap, dated-looking interface.
5. IrfanView – Best Desktop Tool for Windows
If you’re on Windows and need to convert a pile of WebP images, IrfanView is hard to beat. It’s been around since 1996, it’s completely free, it’s tiny (under 5 MB), and it rips through batch conversions faster than any online tool.
How to use it:
- Download and install IrfanView (free from irfanview.com)
- Open your WebP file (File > Open)
- Save as PNG (File > Save As, select PNG)
For batch conversion:
- Go to File > Batch Conversion/Rename
- Add your WebP files
- Set output format to PNG
- Choose output folder and click “Start Batch”
I batch-converted 200 WebP files in under 10 seconds on a mid-range laptop. No file size limits, no daily caps, no internet needed. Transparency preserved on every file.
What I liked: Blazing fast, unlimited batch, tiny footprint, works offline. If you need to process files regularly, this is the tool to install once and forget about.
What I didn’t: Windows only. The UI looks like it’s from 2005. But honestly, for a file converter, who cares.
6. XnConvert – Best Cross-Platform Batch Converter
XnConvert runs on Windows, macOS, and Linux. It’s free for personal use and handles batch image conversion with options online tools can’t match – you can resize, rotate, add watermarks, and convert format all in one pass.
How to use it:
- Download XnConvert from xnview.com
- Drag your WebP files into the Input tab
- Go to the Output tab and select PNG
- Set your output folder and click “Convert”
I ran 500 WebP files through it and the whole batch took about 45 seconds. Transparency was preserved on all files, and the output quality was identical to CloudConvert’s results.
If you need a free tool that works across platforms and handles bulk conversions, XnConvert is my top pick for desktop software. For more file conversion tools, I put together a list of the best free file converter tools that covers other formats too.
What I liked: Cross-platform, powerful batch options, add processing steps (resize, rename, etc.) during conversion.
What I didn’t: The interface is a bit cluttered with options. Takes a minute to figure out where everything is the first time.
7. macOS Preview – Zero Install for Mac Users
If you’re on a Mac, you already have a WebP to PNG converter installed. Preview handles it natively since macOS Big Sur. No downloads, no websites, no accounts.
How to use it:
- Double-click your WebP file (it opens in Preview by default)
- Go to File > Export
- Change the format dropdown to PNG
- Click Save
For batch conversion:
- Select all your WebP files in Finder
- Right-click > Open With > Preview
- In Preview, select all images in the sidebar (Cmd+A)
- File > Export Selected Images, choose PNG
It’s not the fastest for large batches (50 files took about 30 seconds), but it requires absolutely nothing extra. Transparency is preserved. Quality is lossless.
What I liked: Already on your Mac, handles batch well enough for small-to-medium jobs, perfect transparency support.
What I didn’t: Slow with very large batches (500+ files). No advanced options like compression level.
8. ImageMagick – For Developers and Automation
ImageMagick is a command-line tool that’s been around for over 30 years. If you’re comfortable with the terminal, it’s the most powerful and flexible option on this list.
Single file conversion:
magick input.webp output.png
Batch convert all WebP files in a folder:
magick mogrify -format png *.webp
That’s it. Two commands. I converted 1,000 WebP files in 22 seconds on a basic VPS. Transparency preserved, lossless quality, zero interaction required.
You can also control the PNG compression level:
magick input.webp -quality 95 output.png
Or resize during conversion:
magick input.webp -resize 50% output.png
ImageMagick is available on Windows, macOS (via Homebrew: brew install imagemagick), and Linux (usually pre-installed or available via apt/yum). If you’re dealing with automated workflows, scripts, or CI/CD pipelines, this is the tool.
What I liked: Fastest option by far, scriptable, runs anywhere, handles any volume.
What I didn’t: Requires command-line comfort. Not for everyone.
WebP vs PNG vs JPG – When to Use Each
| Feature | WebP | PNG | JPG |
|---|---|---|---|
| Transparency | Yes | Yes | No |
| Lossless mode | Yes | Always lossless | No (lossy only) |
| File size (photo) | Smallest | Largest | Medium |
| File size (graphic) | Smallest | Medium | Larger (artifacts) |
| Browser support | All modern | Universal | Universal |
| Software support | Growing but gaps | Universal | Universal |
| Best for | Web delivery | Graphics, screenshots, logos | Photos |
The short answer: use PNG when you need transparency or pixel-perfect reproduction. Use JPG for photos where file size matters and you don’t need transparency. Use WebP when you control the entire pipeline and know the receiving software supports it. For image compression tips, see our roundup of the best free image compressors.
Tips for Getting the Best Results
Check if your WebP has transparency first. If it doesn’t, PNG might be overkill. JPG will give you a much smaller file. Open the WebP file and look – if the background shows a checkerboard pattern in your image viewer, it has transparency and PNG is the right call.
Don’t re-compress. Some tools offer a “compression level” setting for PNG output. PNG compression is lossless (it doesn’t reduce quality), so crank it up. Higher compression = smaller file with zero quality loss. This is different from JPG where higher compression means lower quality.
Watch out for animated WebP. Animated WebP files (like animated GIFs but in WebP format) won’t convert cleanly to a single PNG. You’ll get just the first frame. If you need all frames, you’ll need to convert to animated PNG (APNG) or extract individual frames. Ezgif handles this well.
Batch conversion saves real time. If you have more than 5 files, skip the online tools. Grab IrfanView (Windows), use Preview (Mac), or run one ImageMagick command. Processing 50 files online means 50 uploads, 50 conversions, 50 downloads. Desktop tools do it in one shot.
Frequently Asked Questions
Is WebP to PNG conversion lossless?
Yes, if your WebP file was saved in lossless mode, converting to PNG preserves every pixel exactly. If the WebP was saved in lossy mode (which is more common on websites), the conversion to PNG is still lossless from that point forward – it captures whatever quality the WebP had, without adding any further degradation. The PNG output will be identical to the WebP input in terms of visual quality.
Does converting WebP to PNG keep transparency?
Yes. PNG supports full alpha channel transparency, just like WebP. All tools on this list preserve transparency during conversion. This is the main reason to choose PNG over JPG as your target format. JPG doesn’t support transparency at all, so transparent areas get filled with a solid color.
Why are my PNG files so much bigger than the original WebP?
WebP uses more advanced compression algorithms than PNG. A typical WebP file is 25-35% smaller than an equivalent PNG. When you convert back to PNG, the file will grow. For photos, expect the PNG to be 2-4x larger. For graphics and screenshots, it’s usually 1.5-2x larger. This is normal and doesn’t mean anything went wrong with the conversion.
Can I batch convert WebP to PNG for free?
Yes. CloudConvert handles up to 25 files per day for free. For unlimited batch conversion, use IrfanView (Windows), XnConvert (Windows/Mac/Linux), macOS Preview, or ImageMagick (command line). Desktop tools have no daily limits and process files much faster than uploading them to a website.
What’s the best free WebP to PNG converter?
For occasional use, CloudConvert is the most polished online option. For regular batch work on Windows, IrfanView is unbeatable. Mac users should just use Preview since it’s already installed. And for developers or anyone comfortable with terminal commands, ImageMagick converts faster than anything else.
