How to convert WebP to JPG
- Choose one valid static WebP within the 25 MiB and 40 megapixel limits.
- Set JPEG quality and choose the color used behind transparent or semi-transparent pixels.
- Press Convert to JPG, review the result, then download the verified JPEG.
WebP vs JPG
WebP supports lossy or lossless encoding and can contain alpha. JPG uses lossy compression and has no transparency, but it is widely accepted for opaque photographs and sharing workflows.
Transparency and background colors
JPG cannot store alpha. PicRecast fills the canvas with your selected white, black, or custom color before drawing the WebP, so fully and partly transparent pixels are deliberately composited rather than unexpectedly turning black.
Animated WebP limitation
Animated WebP is rejected before decoding. PicRecast checks the VP8X animation flag plus ANIM and ANMF chunks and never silently exports only the first frame.
JPEG quality
Quality ranges from 10 to 100 and defaults to 90. Higher values usually retain more detail and use more bytes; moving the control does not start another conversion.
Why file size may increase or decrease
The result depends on source encoding, image detail, dimensions, and the selected JPEG quality. WebP can be more compact than JPEG, so conversion does not guarantee a smaller file.
When JPG is useful
JPG is useful when another service requires JPEG or an opaque photographic file is preferred. Converting formats does not restore detail or improve source quality.
Limitations
This tool handles one static WebP at a time. It does not resize, crop, batch, remove backgrounds, preserve transparency, or improve quality. Lossy JPEG encoding may reduce detail, and metadata or color-profile information may not survive.
Privacy
The selected WebP and generated JPG stay in your browser. There is no conversion API, Supabase Storage upload, AI request, or third-party image service.
Frequently asked questions
What JPG quality should I choose?
90 is a practical starting point. Lower values may reduce size with more visible compression; higher values may retain more detail and create a larger file.
What happens to transparent WebP pixels?
They are composited over the white, black, or custom color you select because JPEG has no transparency channel.
What happens to an animated WebP?
It is rejected before conversion. The tool does not silently select the first frame.
Will the JPG always be smaller?
No. Output size depends on the source and quality setting, so the JPEG may be larger or smaller.
Are WebP metadata and color profiles preserved?
Not guaranteed. Browser decoding and JPEG re-encoding may discard EXIF, ICC, XMP, and other metadata.
Is my WebP uploaded?
No. Validation, decoding, background compositing, and JPEG encoding run locally in your browser.
