Why is the JPG larger than the WebP?

Because WebP compresses better. A 30–50% increase is normal and is the price of compatibility. Lower the quality if size matters more than fidelity.

My transparent areas turned white.

JPEG has no transparency, so they had to become something. White is the default; set any CSS colour in the options. Convert to PNG instead if you need the transparency kept.

Is the animation kept?

No. Animated WebP exists, JPEG is a single still, so the first frame is used. The tool tells you how many frames were in the source.

Can I convert a whole folder of images?

Yes. Drop as many files as you like, or a whole folder. Each keeps its original name with the new extension — IMG_4032.heic becomes IMG_4032.jpg, never converted_1.jpg — and you can download them individually or as a ZIP.

Are my photos uploaded?

No. The decoding and re-encoding happen in this tab using the browser’s own image support. Photos are personal in a way most files are not, and none of them is transmitted. Turn your Wi-Fi off and the converter keeps working.

How large an image can I convert?

The practical ceiling is the browser’s canvas limit, about 268 million pixels in total area — roughly 16,000 × 16,000. Above that you get a clear error rather than a silent failure, and resizing first is the fix. File size itself is limited only by your device’s memory.

WebP to JPG Converter — Batch, No Upload, No Limit

Converts WebP to JPG. You are almost certainly here because you saved an image from a website and something downstream will not open it — Photoshop before 2022, older Office, a print shop, a council upload form, a photo kiosk.

Why the file was WebP in the first place

WebP is Google's image format and it is roughly 25–35% smaller than JPEG at the same visual quality, which is why sites serve it. Browsers all support it. The gap is everything that is not a browser: desktop applications, older operating systems, embedded devices and a long tail of upload forms.

Converting to JPEG trades that size back for compatibility. The file will get bigger — typically 30–50% — and that is the deal.

Quality, and the re-encode

WebP and JPEG are both lossy, so this is a second compression of already-compressed data. At quality 82 the difference is invisible on a photograph. Below about 70 you start to see blocking around hard edges, and text or line art suffers first.

You cannot recover detail the WebP had already discarded — nothing can. What you can avoid is throwing away much more, and quality 82 does that.

Transparency, and the black background problem

JPEG has no alpha channel. When a transparent PNG or WebP is converted, every transparent pixel has to become something.

The naive implementation draws the image onto a fresh canvas and encodes it. A fresh canvas is transparent black, so those pixels come out black — and "my logo has a black box around it" is the single most-reported bug in every image converter that exists.

Here the canvas is filled with your chosen background first, white by default. Set it to whatever the image will sit on: #ffffff for a page, #000000 for a dark one, or any CSS colour.

Metadata is removed, which is usually the point

Re-encoding through a canvas keeps the pixels and discards everything else: EXIF, GPS coordinates, camera make and model, lens, shutter speed, the timestamp, any embedded thumbnail, and the colour profile.

For a photo you are about to publish this is a feature. A JPEG straight off a phone can carry the exact coordinates of where it was taken, and stripping that before it goes anywhere public is good practice — the conversion does it as a side effect.

The one piece of metadata that is honoured before being dropped is the orientation flag. Phones store photos in the sensor's native orientation with a tag saying which way is up; ignoring it produces sideways pictures. It is applied to the pixels, so the result is upright without needing the tag.

If you need the EXIF preserved, this is the wrong tool — a converter that re-encodes cannot keep it.
