| Attribute | This tool |
|---|---|
| Supported input formats | JPG and JPEG |
| Output formats | JPEG, PNG, WebP |
| Compression type | LossyJPEG discards detail permanently by design. PNG output is lossless but far larger for photographs. |
| Quality control | Adjustable, 10 to 100Maps directly to the encoder's quality setting. Moving it genuinely changes the output. |
| Exact output file size | Yes — target in KBThe encoder searches for the highest quality that fits under your limit, then reports the size it actually reached. |
| Resize / image dimensions | Yes — max width and heightAspect ratio preserved. The resizer page adds exact pixel and percentage modes. |
| Batch / bulk processing | UnlimitedFiles are encoded in parallel across a Web Worker pool and can be downloaded as one ZIP. |
| Maximum file size | No limit set by this siteBounded in practice by your device's memory, since each image is held uncompressed while it is processed. |
| EXIF and metadata | Stripped by defaultCamera model, timestamps and GPS coordinates are removed. You can switch it off. |
| Transparency / alpha channel | Not applicable to JPEGJPEG has no alpha channel. Choose PNG or WebP output if you need transparency. |
| Chroma subsampling control | Not availableThe browser's encoder chooses it and exposes no setting. We will not add a control that cannot affect the output. |
| Progressive JPEG control | Not availablecanvas.toBlob gives no control over progressive encoding. Use MozJPEG or ImageMagick if you need it. |
| Color profile handling | Converted to sRGBA browser canvas works in sRGB, so wide-gamut images are converted. Correct for the web, wrong for print masters. |
| Bit depth | 8 bits per channelThe maximum a browser canvas provides. HDR and 10-bit output need AVIF, which browsers cannot write. |
| Animation support | Not supportedA canvas decodes only the first frame of an animated file, so animation is out of scope rather than half-supported. |

How it works
How to webp to png converter
Step 1: Add your files
Drag them onto the drop zone, click to browse, or paste from the clipboard. Batches are fine.
Step 2: Set the quality
The default suits most images. Move it if you want a smaller file or a more faithful one.
Step 3: Download the converted files
Each row shows the size before and after. Save them one at a time or as a single ZIP.
Features
What this tool does
Batch processing
Queue as many image files as you like. A Web Worker pool runs them in parallel, so a large batch never freezes the page.
Real quality control
The slider maps straight to the encoder setting. Move it and the output genuinely changes — nothing here is cosmetic.
Exact target size
Ask for 200 KB and the encoder finds the highest quality that fits, then reports the size it achieved.
EXIF and metadata stripping
Camera model, timestamps and GPS coordinates are removed on the way out — worth doing before publishing a phone photo.
Format conversion
Write the result as JPEG, PNG or WebP whatever you put in, so you can test which is smallest.
Nothing is uploaded
The whole pipeline runs in your browser through the Canvas API. Disconnect your network after the page loads and it still works.
No watermark, no sign-up
The output is your image and nothing else. There is no account, no daily quota and no paid tier holding back a feature.
Works on mobile
The layout, the drop zone and the results table are all usable on a phone, and mobile browsers run the same encoder as the desktop ones.

About this conversion
Expect the file to get bigger
This conversion almost always produces a larger file, and that is not a fault — it is the point. WebP is a compressed format built for the web; PNG is lossless and stores every pixel exactly. Going from one to the other means giving up the compression that made the WebP small.
A 200 KB WebP photograph commonly becomes a 1.5 MB PNG. If your goal was a smaller file, this is the wrong conversion; if your goal is compatibility with something that refuses WebP, it is exactly right.
Why people need this
The usual reason is software that has not caught up. Plenty of content management systems, older desktop applications, print workflows and internal tools still reject a WebP upload outright, even though every browser has displayed the format for years.
Converting to PNG is the safe answer because PNG is universally understood and lossless, so nothing degrades on the way. If file size matters more than universality, converting to JPEG instead will produce something far smaller — at the cost of transparency.
Lossy and lossless compression are not the same thing
Lossless compression rewrites the file so every pixel survives exactly — decode it and you get the original back, byte for byte. PNG, GIF, lossless WebP and ZIP all work this way.
Lossy compression discards detail on purpose. JPEG converts the image to a frequency representation and throws away the high-frequency detail your eye is least likely to miss. That is irreversible, and it is how lossy reaches sizes lossless cannot: a photograph saved as PNG is routinely five to ten times larger than the same photograph as JPEG.
Neither is better. Photographs suit lossy encoding; screenshots, logos and line art suit lossless, because lossy encoders leave haloes around hard edges.
Transparency and color JPEG cannot carry
JPEG has no alpha channel and cannot store transparency. Converting a transparent PNG forces those pixels to become something, and most tools fill them with black — which is why a logo exported to JPEG arrives in an unwanted dark box. Keep it as PNG, use WebP (alpha support, typically 25–35% smaller than PNG), or flatten onto a chosen background deliberately.
Color is the other gap. Screens mix additively in RGB; printing presses mix subtractively in CMYK, and converting between them always approximates. A CMYK JPEG is converted to RGB before a browser can display it, and saturated cyans and deep blues can shift noticeably. Compress and resize in RGB for screens, and keep a separate CMYK master for print.
Questions
Frequently asked questions
Every answer below is present in the page source, expanded, so it can be read without opening anything.
Is transparency preserved?
Yes. Both WebP and PNG carry a full 8-bit alpha channel, and it is copied across untouched. This is the main reason to choose PNG rather than JPEG as the destination.
Why is my PNG so much larger than the WebP?
Because PNG is lossless. It records every pixel exactly, with no ability to discard detail your eye would not miss. The WebP was small precisely because it did discard some. Converting cannot recover that detail, but it does have to spend bytes storing what remains, exactly.
Does converting back improve the quality?
No, and it is worth being clear about that. Detail discarded by the original WebP encode is gone permanently. The PNG is a faithful, larger copy of the compressed image — not a restored original.
Can I convert animated WebP files?
No. This tool works on still images, and an animated WebP would be reduced to its first frame. There is no animation support here and none is advertised.
Should I convert to JPG instead?
If the image is photographic and has no transparency, yes — the JPEG will be a fraction of the PNG's size and will be accepted by the same software. Use PNG when transparency or exact pixel fidelity matters.
Are my files uploaded?
No. Decoding and re-encoding both happen in this browser tab on your own device.

Image Formats WebP vs JPEG: Which Should You Use, and When JPEG Still Wins
WebP produced a 27.0 KB file against MozJPEG's 41.1 KB on the same photograph at slightly higher measured fidelity — 34% smaller. It also produced a larger file than JPEG on random noise. The advantage is real and content-dependent.
