How to Convert WebP to PNG
Add Your WebP Files
Drag and drop WebP images into the converter or click to browse. Multiple files are supported for fast batch conversion — add as many as you need.
Instant Lossless Conversion
Each WebP image is decoded and re-encoded as PNG using the browser's native Canvas API. The output is lossless — every pixel is preserved exactly, including transparent areas.
Download Your PNG Files
Download converted files individually or as a single ZIP archive. Your original WebP files are never modified — they remain safely on your device.
What Is the WebP Format?
WebP is a modern image format developed by Google, first released in 2010 as part of the broader effort to make the web faster. It supports both lossy compression (smaller than JPEG) and lossless compression (smaller than PNG), plus transparency and animation. This versatility has made it the default image format on many content management systems, e-commerce platforms, and CDN services.
However, WebP's strength on the web is also its weakness off the web. Many desktop applications — including older versions of Adobe Photoshop, Affinity Photo, and Microsoft Paint — cannot open WebP files. Graphic designers who download assets from the web frequently encounter WebP images they cannot import into their workflow without first converting to a more standard format.
PNG (Portable Network Graphics) is the gold standard for lossless raster images. It supports full alpha-channel transparency, 16-bit color depth, and is universally recognized by every operating system, browser, and image editor. Converting WebP to PNG gives you a pixel-perfect copy that works everywhere, with transparency fully intact.
WebP vs PNG — Format Comparison
| Feature | WebP (Input) | PNG (Output) |
|---|---|---|
| Compression type | Lossy or lossless | Lossless only |
| Transparency | Supported | Full alpha channel |
| Animation | Supported | Not supported (use APNG) |
| Browser support | All modern browsers | All browsers, all versions |
| Desktop app support | Limited (recent apps only) | Universal |
| File size (typical image) | 150–600 KB | 400 KB–3 MB |
| Color depth | 8-bit per channel | Up to 16-bit per channel |
Why Convert WebP to PNG?
PNG offers several advantages over WebP when you need the image outside of a web browser:
- •Preserving transparency — PNG maintains the exact same alpha channel as your WebP file, making it perfect for logos, icons, and product images with transparent backgrounds.
- •Graphic design workflows — Photoshop, Illustrator, Figma, and Sketch all handle PNG natively. Converting WebP assets to PNG lets you integrate web-sourced images into design projects seamlessly.
- •Lossless quality guarantee — Unlike JPG, PNG preserves every pixel without compression artifacts. When you convert a lossy WebP to PNG, you lock in the current quality level and prevent further degradation from additional saves.
- •Document embedding — Word processors, presentation software, and PDF generators handle PNG images more reliably than WebP. Converting ensures your images display correctly in reports and slides.
- •Cross-platform sharing — Not everyone uses a modern browser or device. PNG is recognized by virtually every piece of software ever made, from ancient Windows XP apps to the latest macOS tools.
- •Archival purposes — PNG's lossless nature makes it ideal for long-term storage. Unlike WebP, which may face future compatibility challenges as formats evolve, PNG is an ISO standard with guaranteed long-term support.
Real-World File Size Examples
Below are typical file sizes when converting WebP images to lossless PNG. Since PNG is uncompressed at the pixel level, files will generally be larger.
| Source | WebP Size | PNG Size |
|---|---|---|
| Logo with transparency (500×200) | 18 KB | 45 KB |
| Product photo (1200×800) | 95 KB | 1.8 MB |
| UI screenshot (1920×1080) | 185 KB | 980 KB |
| Illustration with flat colors (2000×1500) | 120 KB | 350 KB |
Sizes vary by image content. Images with large flat-color areas (screenshots, illustrations) compress well as PNG. Photographic images produce significantly larger PNG files.
Your Privacy Is Built In
WebP-to-PNG conversion runs entirely in your browser using the Canvas API. The image is drawn onto an in-memory canvas, exported as a PNG blob, and made available for download — without any data leaving your device. There is no server upload, no cloud processing, and no third-party access.
This local-first approach means you can convert sensitive images — design mockups under NDA, proprietary product photos, confidential documents — with total confidence. The process works even when you are offline. All image data is cleared from memory when you close the browser tab.
Free WebP to PNG Converter — Lossless, No Sign-up — Frequently asked questions
Why convert WebP to PNG?
PNG is a lossless format that preserves transparency. Use PNG when you need to edit the image further, need a transparent background, or want to avoid any compression loss.
Are my images sent over the internet?
No! Conversion happens entirely in your browser using the native Canvas API. Your images never leave your device.
Will transparency be preserved?
Yes. PNG fully supports transparency. If your WebP image has a transparent background, it will be preserved in the PNG output.
Will the PNG be larger than the WebP?
Usually yes, since PNG is lossless and WebP uses advanced compression. If file size matters, use our WebP to JPG converter instead.
Can I convert animated WebP to PNG?
Our converter processes the first frame of an animated WebP and produces a static PNG. For multi-frame animation, consider APNG or GIF formats instead.
Does WebP to PNG conversion affect image resolution?
No. The conversion preserves the exact pixel dimensions of the original WebP file. A 1920×1080 WebP will produce a 1920×1080 PNG with identical visual content.
Why can't I open WebP files in Photoshop?
Older versions of Adobe Photoshop (before 2024) do not support WebP natively. Converting to PNG gives you a universally compatible file that opens instantly in any version of Photoshop, GIMP, or any other editor.
Is PNG better than WebP for printing?
For printing, PNG is more universally accepted by print services and prepress software. While both formats can deliver high-quality output, PNG avoids potential compatibility issues with print RIP software.
How do I download a WebP image from a website?
Right-click the image and select 'Save image as…'. Most browsers will save it with a .webp extension. Then simply upload it to our converter to get a PNG version that works everywhere.
Can I use this converter on my phone?
Yes! The converter works on any device with a modern browser — iPhone, Android, iPad, or desktop. Since processing happens locally, performance depends on your device, but most smartphones handle it without issues.
