Convert WebP to PNG
For a logo or sticker whose transparent edge has to survive into a design tool — PNG keeps the alpha channel that a flattened JPG throws away.

Malaysian rules & edge cases
Nine conversions, one rule. Any of JPEG, PNG and WebP can become any of the three. The output type is read from the bytes the encoder actually produced — not from the label you picked — so a file named .webp is a real WebP or the tool says why not.
| Output | Transparency | Quality dial | Typical size |
|---|---|---|---|
| JPEG | No — transparent pixels take the background colour you choose (white by default) | 0.3–0.95 | Smallest for photos; the format every form, portal and print shop accepts |
| PNG | Kept | None — lossless | Largest. A photo converted from JPEG to PNG is usually 3–5× bigger, because PNG cannot throw detail away |
| WebP | Kept | 0.3–0.95 | Smallest of the three at the same visual quality; every current browser reads it, older Office installs do not |
What happens to the pixels. The EXIF orientation is read first and baked into the image, so a portrait photo stays portrait once the tag that described it is gone. Then the image is redrawn through a canvas and encoded again — which is why every conversion drops the camera model, the GPS fix, the timestamp, the software tag and the colour profile. Wide-gamut photos (Display P3, Adobe RGB) come back as sRGB: slightly less saturated, never shifted in hue.
What it does not do. It does not resize: 4000 px in stays 4000 px out, except an image above 16.7 megapixels, which is scaled into the canvas limit and says so on its row. It does not read HEIC, AVIF or GIF, and it cannot make a JPEG transparent — no tool can add an alpha channel that was never recorded.
Honest limit. WebP output needs a browser that can really encode it. Safari on iOS and macOS cannot, and asking for image/webp there silently returns a PNG — so this tool checks the type of the bytes it got and, when it is not WebP, saves a JPEG named .jpg and says so. AVIF output is not offered at all: no browser's canvas can encode it (Chrome answers a request for AVIF with a PNG), and a fake would be worse than an omission.
A batch is one download. Two or more images arrive as a single ZIP, built inside the tab, with duplicate names numbered (baju.jpg, baju-1.jpg) instead of overwriting each other. Nothing leaves the device: open the Network panel, press Run, and no request appears.
Before and after
Before
logo-kedai-kopi.png — 1000×1000 — transparent background
produk-shopee-01.jpg — 1200×900 stored, EXIF orientation 6 — iPhone 15 Pro — GPS 3.1390, 101.6869After
logo-kedai-kopi.jpg — 1000×1000 — transparency filled with white
produk-shopee-01.webp — 900×1200 upright — camera, GPS and date removedHow it works
- Drop your images, or press "Load sample data" for a transparent PNG logo and a product photo that really carries camera, GPS and orientation tags.
- Choose the output format. For JPEG, pick the colour that goes under transparent pixels; quality applies to JPEG and WebP only, because PNG is lossless.
- Press Run, check each row — real size, real dimensions, what was removed — then download one image or the whole batch as a ZIP. Nothing left this tab.
FAQ
Does the transparency survive?
Yes. PNG and WebP both carry an alpha channel, so a transparent logo stays transparent and nothing is painted underneath. Only JPEG output needs the background colour choice, which is why that control hides itself when PNG is selected.
Why is the PNG so much bigger?
Because it is lossless: every pixel is stored exactly, while the WebP was compressed with a lossy model. A 60 KB WebP photo can become a 400 KB PNG. That trade is the point — you are buying pixels that will not degrade on the next save.
Does the quality slider apply?
No. PNG has no quality setting, so the slider is hidden and the output is always maximum quality. If you wanted a smaller file, WebP or JPEG is the answer, not a different PNG setting.
