Why use Aback Images for webp to png
Where the PNG goes next
PNG opens in every browser, operating system and image editor.
PNG next to WebP
The PNG keeps the decoded pixels without lossy compression, so expect it to be larger than the WebP.
No new artefacts
WebP is already lossy, since it stores lossy VP8 coding or lossless VP8L; the PNG keeps the decoded pixels losslessly, so this step adds no compression damage of its own.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
WebP vs PNG
What changes from WebP to PNG
Encoding: the WebP uses lossy VP8 coding or lossless VP8L; PNG uses lossless DEFLATE with a prediction filter chosen per row, and the download is a lossless 8-bit PNG with full alpha.
Bit depth: 8 bits per channel in the WebP; PNG allows 1, 2, 4, 8 or 16 bits per channel, and the PNG written here has 8 bits per channel.
Colour: RGB; lossy WebP stores colour at half resolution (4:2:0) in the WebP; PNG supports RGB, greyscale, or an indexed palette of up to 256 colours, written here as 8-bit sRGB.
Transparency: the WebP stores it as a separate alpha plane, available in lossy as well as lossless files; the PNG keeps it as a full alpha channel, so edges and shadows can fade smoothly.
Animation: ANMF frame chunks, each with its own delay and blending; the PNG holds one image, so only the first frame is converted.
Metadata: the WebP can carry EXIF, XMP and ICC chunks; PNG can carry text chunks, an ICC profile, physical resolution and EXIF in an eXIf chunk, but nothing is copied across.
About WebP
WebP is Google's web image format. It supports lossy and lossless compression, transparency and animation, and is typically 25 to 35 percent smaller than JPEG at the same visual quality.
A WebP is a RIFF file: 'RIFF', a length, 'WEBP', then chunks. A simple lossy file is one VP8 chunk and a lossless one is VP8L; the extended VP8X header announces alpha, animation, ICC, EXIF or XMP chunks.
WebP files usually come from websites, Chrome's Save image as, CDNs and Android apps.
About PNG
PNG stores pixels losslessly with full alpha transparency. It is ideal for screenshots, logos, UI and anything with sharp edges, but photos saved as PNG are several times larger than JPEG.
A PNG opens with an 8-byte signature and is a chain of chunks, each with its own CRC: IHDR (size, depth, colour type), optional PLTE and tRNS for palettes, one or more IDAT chunks with the compressed rows, and IEND.
When converting WebP to PNG makes sense
PNG is the better choice for screenshots, logos, graphics and anything that needs transparency, while WebP suits images on websites and in apps.
PNG strengths: Lossless: no quality loss, ever; Full transparency with smooth edges; Perfect for text, screenshots and graphics. Drawbacks to weigh: Large files for photographs; No standard animation (that is APNG).
Limitations
- WebP images saved from websites are often already resized and compressed for the page, so the result cannot be sharper than that copy.
- A PNG of a photograph is often several times larger than a JPG; PNG pays off for screenshots, graphics and anything with transparency.
- The PNG is written in full colour; Compress PNG can shrink it further with a palette.

Frequently asked questions
Does converting WebP to PNG lose quality?
PNG is written losslessly, so the pixels are stored exactly as decoded. Artefacts already in the WebP stay, but nothing new is lost.
Is transparency kept in the PNG?
Yes. WebP stores it as a separate alpha plane, available in lossy as well as lossless files, and the PNG is written with an alpha channel, so transparent areas stay transparent.
Will my animated WebP stay animated?
No. PNG holds a single image, so only the first frame is kept. Convert to animated WebP, APNG or GIF to keep the motion, or export every frame with the GIF Frame Extractor.
Which apps open PNG files?
Every browser, operating system and image editor.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
