WebP to PNG Converter
Convert WebP images into lossless PNG files in your browser. Preserve transparent pixels, resize without stretching and process one file or a complete batch without sending images to a conversion server.

Selected images remain on this device; the converter does not send image bytes to a conversion API.
Practical limits and browser requirements
Total input is limited to 150 MB. Each WebP may contain up to 24 megapixels with a maximum side of 12,000 px; PNG output is limited to 16 megapixels and 8,192 px per side. Your browser must decode WebP and support Canvas. Animated WebP becomes one still PNG frame.
Your WebP images
A fill cannot remove an opaque background already inside the WebP.
Fit preserves the aspect ratio. Enlargement is off by default.
Honest PNG output
PNG encoding is lossless, so a JPG-style quality slider would not control this export. Dimensions and image complexity affect the resulting size.

A CLEAR THREE-STEP WORKFLOW
How to convert WebP to PNG
Add your WebP files
Select WebP images or drag them into the workspace. The tool checks the actual file signature, so a different format renamed with a .webp extension is rejected.
Set size and transparency
Keep original dimensions or fit each image within maximum width and height. Preserve alpha transparency or flatten transparent pixels onto white or a custom colour.
Inspect and download
Review the output dimensions, byte size and percentage difference. Save PNG files separately or download all successful results in one ZIP.
FORMAT CHANGE, NOT MAGIC
What changes when WebP becomes PNG?
WebP and PNG are raster formats, but they store pixels differently. WebP can use lossy or lossless compression and can contain transparency or animation. PNG uses lossless compression and is widely used for screenshots, diagrams, logos and interface assets.
The converter asks the browser to decode the WebP, draws the decoded frame onto a Canvas and creates a new PNG. This avoids another lossy encoding step, but it cannot recover detail already discarded when a lossy WebP was created.
Browser Canvas creates a fresh file rather than copying the original container. EXIF details, comments, colour profiles and editing history are not intentionally retained. Keep the source whenever metadata, animation or later editing matters.
Preserve WebP transparency in PNG
Both WebP and PNG can store an alpha channel. If the source contains fully or partly transparent pixels, Keep transparency allows those pixels to remain transparent in the PNG.
White or custom colour fills the Canvas before the WebP is drawn. Transparent areas reveal that colour, including soft edge pixels. A fill is useful when the receiving system expects an opaque image or when the final background is known.
This is not a background-removal feature. An opaque background already painted into the WebP remains part of the image. Remove it in an editor before conversion if you need a cut-out subject.
Resize WebP during PNG conversion
Fit mode uses one scale ratio so the output stays inside both limits without stretching. For example, a 2400 × 1200 WebP fitted within 1200 × 1200 becomes a 1200 × 600 PNG, not a square.
Upscaling is disabled by default. Making an image larger creates more pixels but does not reveal missing detail. Enable enlargement only when another system requires minimum dimensions, then check text, edges and fine patterns at the real display size.
Each file also has a dimension override. This helps when most images need one batch setting while a particular logo, screenshot or illustration should keep its original size.
Why PNG output can be larger than WebP
PNG is lossless, while many WebP images use adjustable lossy compression. Re-encoding a photo as PNG stores the decoded pixel result without another lossy save, but the file can grow considerably. It does not restore texture or detail removed by the earlier WebP encoder.
Flat graphics, limited colours and repeated areas may compress efficiently as PNG. Detailed photographs, noise and subtle gradients usually create larger PNG files. The converter reports the actual output bytes and percentage change instead of claiming every result will be smaller.
If a website already displays the WebP correctly, converting it to PNG may increase transfer size without a visible benefit. PNG makes more sense when a design app, upload form, print workflow or older integration specifically requests it.
Private browser conversion with sensible limits
Conversion takes place with browser APIs after the page loads. Selected image bytes are not uploaded to a GetTransfy conversion server. Files are handled sequentially to reduce peak work, and the Stop control ends the queue after the current operation.
Large decoded images can still use significant memory, especially on older phones. The page limits file size, dimensions, total batch input and total converted output. If a device slows down, use fewer files or resize the originals first.
The tool verifies WebP signatures before adding files and verifies that exported blobs are PNG. A damaged file or unsupported browser decoder produces a visible row-level error instead of a misleading download.
WebP to PNG questions
Can I convert multiple WebP files at once?
Yes. Add up to 30 files within the stated limits. Apply shared settings, override dimensions per file and download individual PNGs or one ZIP.
Does PNG improve a lossy WebP?
No. PNG avoids a new lossy save, but it cannot rebuild information discarded during the original WebP compression.
Will animated WebP stay animated?
No. Browser Canvas produces one still PNG frame. Keep the original WebP when motion matters.
Are my WebP files uploaded?
No conversion upload is performed. Images are decoded and exported locally with browser APIs after the page has loaded.
Why is the PNG larger?
Detailed WebP photos can use efficient lossy compression, while PNG stores the decoded pixels losslessly. Different compression goals often produce different file sizes.
