What does WebP to PNG do?
It loads one WebP, draws the decoded pixels to a canvas, and encodes a PNG with canvas.toBlob. It does not rename the extension without re-encoding.
Open one WebP, optionally cap max width or height, convert in the browser, then compare WebP and PNG before download.

The guide and instructions on this page are available while the tool loads.
WebP to PNG decodes one supported WebP and exports the pixels as a PNG for editors, upload fields, presentations, and apps that still prefer PNG. It is a one-direction compatibility workflow: WebP in, PNG out—not a general converter and not a compressor.
Upload one image/webp or .webp file up to 20 MB. Review the decoded preview on a checkerboard, leave dimensions unchanged, or set optional max width and/or max height for proportional downscaling that never enlarges. Convert, then use the before/after slider to compare appearance, dimensions, and byte sizes. Download is {base}.png with automatic and manual download—no batch queue and no ZIP.
PNG stores the decoded canvas pixels without an extra lossy quality slider. That does not restore detail already discarded by a lossy WebP source. Output is often larger than the WebP and can occasionally be similar. The canvas is cleared before drawing so decoded full and partial alpha can continue into PNG when the browser supplies it. Animated WebP becomes one still PNG from the decoded frame. EXIF/XMP, ICC profiles, DPI, HDR, and original bit-depth layout are not deliberately copied.
Conversion stays in the browser via the Image element, object URL, canvas, and canvas.toBlob("image/png"). WebP bytes are not posted to a conversion API. Ordinary website assets may still load. Identified analytics may include sizes, dimensions, hasTransparency, sizeDeltaPercent, and error codes—not filenames or raw image contents.
Renamed or corrupt files that cannot decode are rejected. There is no PNG quality control and no target-kilobyte solver. Large pixel dimensions can stress memory even under 20 MB. Reset clears the workspace and is not a dedicated mid-run cancel control. Keep the original WebP when you need animation, smaller delivery size, or metadata the PNG export does not carry.
Typical tasks this tool is built for.
WebP decoding, optional downscaling, canvas rendering, and PNG encoding run locally. The WebP file is not uploaded for conversion. DevToolKit may receive usage or diagnostic metadata such as dimensions, transparency detection, byte counts, sizeDeltaPercent, page context, and result codes. Identified analytics do not include the filename or raw WebP bytes.
Practical tips before you download or share the output.
One WebP up to 20 MB. Optional max width/height downscale only. Output {base}.png via Image + canvas.toBlob("image/png"). PNG is lossless for decoded pixels—does not restore lossy WebP detail; often larger. No quality slider, target size, batch, or ZIP. Transparency via clearRect when decoded alpha is present. Animated WebP becomes a still frame. Metadata/profiles not copied. Analytics may include sizes, dimensions, hasTransparency, sizeDeltaPercent, and codes—not filename or raw WebP.
Longer reads that pair well with this tool.

Convert one supported image at a time, review transparency and dimensions, then test the exported file in the destination that needs it.

Speed up pages with In-browser image resize, compression, and format conversion — the highest-impact levers DevToolKit actually provides.
Common next steps after using this tool.
Decode a supported image and re-encode it to JPG, PNG, WebP, or AVIF with quality, transparency, and optional resize controls.
Compress a JPG, PNG, WebP, or AVIF image with format, quality, and optional resize controls.
Remove an image background, review the cutout, refine its edge softness, and export it with transparency or a new background.
Turn one or more JPG and JPEG photos into a single ordered PDF with one image per page.
Build one ordered PDF from mixed supported image formats, with one ready image on each page.
Select a rectangular region from one JPG, PNG, or WebP with aspect presets, pixel coordinates, and format-aware export.
Situations where this workflow saves time.
It loads one WebP, draws the decoded pixels to a canvas, and encodes a PNG with canvas.toBlob. It does not rename the extension without re-encoding.
Files with type image/webp or a .webp name. Other formats are rejected. Decode failures reject renamed or corrupt files.
One WebP per run. There is no batch queue, append-more list, or ZIP packaging.
20 MB. There is no separate combined-size limit and no hard pixel-dimension cap, but large canvases can use substantial memory.
Animation is not preserved. The browser-decoded frame is exported as one static PNG.
The canvas is cleared before drawing so decoded alpha can remain in PNG. Not every WebP has transparency—verify the checkerboard preview and destination app.
Partial transparency can continue when the browser decodes it onto the cleared canvas. Display still depends on the destination application.
Not unless you set optional max width or max height. Limits scale proportionally and never enlarge the image.
PNG stores the decoded canvas pixels without an extra lossy quality slider. It is not byte-for-byte identical to the WebP file.
No. Softness, blocking, or detail already discarded by the WebP remains missing in the PNG.
PNG encodes the decoded raster losslessly, while many WebP files use more efficient compression. Growth is common for photos and complex graphics.
No deliberate copy exists. Canvas re-encoding typically leaves EXIF, XMP, GPS, capture date, and related chunks behind.
They are not deliberately copied. Color appearance can change under standard browser canvas handling.
There is no separate orientation rewrite. Browser Image decoding may apply orientation before pixels are drawn.
Locally in the browser. WebP bytes are not uploaded for conversion.
The download is named {base}.png, using the source basename without the .webp extension.
No. One PNG is produced, with automatic download plus a manual Download PNG button.
Yes. The settings screen shows the decoded WebP. After conversion, a slider compares that preview with the encoded PNG result.
It can when the mobile browser decodes WebP and exports PNG. Large images may be slow or memory-heavy on phones.
There is no dedicated cancel control during encoding. Reset clears the workspace afterward and is not true mid-run cancellation.
This page accepts WebP only and always outputs PNG for compatibility. PNG to WebP encodes lossy WebP with quality presets for web delivery.
Identified events may include engine, input/output bytes, width, height, hasTransparency, sizeDeltaPercent, and error codes. They do not include the filename or raw WebP bytes.
