Picture Batch WebP to JPG
WebP to JPG
WebP is what you get when you save an image from most of the web, and it is the format that a surprising amount of software still refuses — older photo editors, some print services, plenty of document and slide tools, and most things with a file dialog older than a few years. JPEG is the format none of them refuse.
Drop WebP images here
WebP files — or any of PNG, JPEG, AVIF, BMP, ICO, TIFF, GIF or camera raw (CR2, CR3, NEF, ARW, DNG, RAF, ORF, RW2). Everything runs on this device.
Your images never leave this device. They are decoded and re-encoded by your own browser, and the security policy on every page blocks this site from sending them anywhere.
Lossy, no transparency, opens absolutely everywhere, small for photographs.
The standard range for photographs. Hard to distinguish from the original.
Images keep their original dimensions.
JPEG cannot store transparency. Nothing in the queue currently has transparent pixels, so this has no effect yet.
Exif is carried across where both formats can hold it. Nothing currently in the queue has any.
Exif metadata can be carried from WEBP to JPEG. Colour profiles are not, because decoding converts the image to sRGB.
What happens to your image
The result depends on the quality setting rather than the source. Matching the original file size usually means quality around 80.
| Property | Outcome |
|---|---|
| Transparency | Not preserved: Lost. JPEG cannot store it, so transparent areas are filled with a background colour you choose. This cannot be undone in the output. |
| Image quality | Partly preserved: JPEG is lossy: the image is re-compressed and detail is discarded to make the file smaller. The quality control decides how much. |
| Generation loss | Partly preserved: Both formats are lossy, so this is a second round of compression on top of the first. It cannot restore anything the WebP already threw away, and at a low quality setting it will add its own losses. |
| Colour | Partly preserved: Converted to sRGB. Decoding an image colour-manages it into the browser's own space, so the output is sRGB and is left untagged, which every viewer reads as sRGB. A wide-gamut source is reported before conversion. |
| Exif metadata | Preserved: Carried across if you leave metadata switched on, or removed completely if you switch it off. Camera, date and any location tag travel together. |
| Orientation | Preserved: Applied to the pixels, and the tag is reset to upright afterwards so nothing rotates the image a second time. |
| Animation | Not preserved: Only the first frame is converted. Animation is not carried across. |
Lossy to lossy, so quality is the decision to make
A WebP saved from a website has already been compressed once. Encoding it as JPEG compresses it again, with different artefacts that do not cancel out. At quality 85 the second pass is difficult to see on a photograph; below 70 it becomes obvious in smooth gradients and around edges.
A WebP can also be lossless — the format supports both, and lossless WebP is common for logos and screenshots. Converting one of those to JPEG introduces loss where there was none, and if the image contains text or flat colour it will look noticeably worse. PNG is the right target for those.
Transparency has nowhere to go
WebP supports an alpha channel and JPEG does not, so a transparent WebP must be flattened onto something. You choose the colour; the tool does not quietly assume white and leave you to discover it against a dark background.
The queue tells you before conversion whether the file actually has transparent pixels, so you know whether the choice matters for this particular image.
Only the first frame of an animated WebP
WebP can hold animation, and JPEG cannot hold anything but a single image. Where an animated file is detected the first frame is converted and the queue says so plainly, so a silently still result is never a surprise.
If something goes wrong
Where the image was transparent it is now white.
JPEG has no alpha channel; white is the default background.
What to do: Set the background colour before converting, or convert to PNG instead and keep the transparency.
The JPG is bigger than the WebP.
WebP is a more efficient format, so matching its quality often costs more bytes in JPEG.
What to do: Normal and expected. If size matters more than compatibility, keep the WebP.
The image looks worse than the original.
Either a second round of lossy compression, or the source was lossless WebP.
What to do: Raise the quality to 90 or above, or convert to PNG if the image has text or flat colour.
Questions
Why do so many programs still not open WebP?
WebP arrived in 2010 but only became universal in browsers around 2020, and desktop software follows years behind. Anything with an image importer written before then is likely to refuse it.
Can I convert several WebP files at once?
Yes. Add a folder's worth, watch real per-file progress, and download the finished set as a ZIP with a manifest of what was converted.
Is any quality lost converting WebP to JPG?
Yes. Both are lossy formats and this is a second compression pass. At quality 85 it is hard to see on photographs; on text and flat colour it is visible, and PNG is the better target.
