WebP to PNG Converter — Free, Private, No Upload
Turn WebP images into lossless PNGs that open in any editor and keep transparency, right on your device. Nothing is uploaded, no limits, no signups.
Converting WebP to PNG gives you a lossless image with transparency that opens in any editor or viewer, including older software that doesn't recognise WebP. It's the right target when you need to edit the picture or hand it to a tool that specifically expects PNG — the cost is a larger file, since PNG doesn't compress as tightly as WebP.

Most converters send your photos to a server you know nothing about. Filexum can't, because it never asks for them: the conversion runs inside your browser, on your own device. You don't have to take our word for it — open your browser's Network tab and watch it stay empty, or turn off Wi-Fi and convert anyway.

Why WebP?
WebP is a modern image format Google released in 2010, built to make photos smaller on the web without a visible drop in quality. It supports both lossy and lossless compression as well as transparency, and typically produces files noticeably smaller than an equivalent JPG or PNG.
Every current browser — Chrome, Safari, Firefox and Edge — displays WebP, so it's an excellent choice for websites and for saving space on your own device. A handful of older apps still don't accept it, so when maximum compatibility matters, JPG remains the safest bet.
Why PNG?
PNG arrived in 1996 as a free, patent-unencumbered image format, and it does something JPG can't: it is lossless. Every pixel is preserved exactly, and it supports full alpha transparency — which makes it the go-to format for screenshots, logos, diagrams and any image with sharp edges or text.
That perfect quality has a cost in size: a photographic PNG can be several times larger than the same picture as a JPG. If you want a pristine, editable copy of a HEIC photo — or you need transparency — PNG is the right target. For small, shareable files, JPG or WebP will serve you better.

WebP to PNG — frequently asked
Are my WebP files uploaded anywhere?
No. Everything runs inside your browser, on your own device — no file, filename or hash ever leaves your machine. You can convert in airplane mode.
Why convert WebP to PNG?
Because PNG opens in virtually every image editor and viewer, including older ones that reject WebP, and because it's lossless — ideal when you plan to edit or archive the image.
Does the PNG keep the WebP's transparency?
Yes. PNG supports full alpha transparency, so any transparent areas in the WebP carry over exactly into the PNG.
Why is the PNG bigger than the WebP?
PNG is lossless and doesn't compress as aggressively as WebP, so files grow — especially for photos. You're trading size for perfect quality and broad compatibility.
Is the conversion lossless?
The PNG itself is lossless. If the original WebP was saved in lossy mode, the PNG faithfully preserves that already-compressed image without adding any further loss.
Is it free with no limits?
Yes — no signup, no ads, no watermark, and no cap on how many WebP files you convert beyond your device's memory.
