This converter uses your browser's Canvas encoder. It keeps the PNG's original pixel dimensions, applies the selected matte beneath every transparent or semi-transparent pixel, and exports an opaque JPEG. The result includes a side-by-side preview and honest size metadata, since a simple graphic can sometimes be larger as a high-quality JPG.

Runs entirely in your browser - no upload, no sign-up.
Your PNG is converted locally and never uploaded.
How does a PNG to JPG converter work?
A PNG to JPG converter decodes a PNG image, places it over a solid background, and re-encodes the pixels as a JPEG. Choose the quality and the color used for transparent areas, then compare the original and output sizes. The conversion runs locally in your browser, so nothing is uploaded.

How to use
- 01Choose a PNG
Drop a PNG into the converter, pick it from your device, or load the built-in transparent example.
- 02Set the JPG quality
Move the quality slider. Around 80 to 90 is a practical starting range for photographs and web images.
- 03Choose a background
Pick the solid color that should replace PNG transparency. The preview shows the actual flattened JPG result.
- 04Compare and download
Convert the image, review both file sizes and settings, then download or copy the result.

Who it's for
- Website editors can turn photo-like PNG files into widely compatible JPG assets and compare the file-size change before publishing.
- Applicants and office teams can create JPG files for forms, document systems, and email workflows that do not accept PNG.
- Designers and shop owners can place transparent product art on an intentional white, gray, black, or brand-colored background.
- Privacy-conscious users can convert personal or client images without sending the source file to a conversion server.
FAQ
Is my PNG uploaded during conversion?
No. Your browser reads the PNG, draws it onto a local Canvas, and creates the JPG on your device. The original image and converted file are not sent to a processing server, and you do not need an account.
Is this PNG to JPG converter free?
Yes. You can convert, preview, copy, and download JPG images without a subscription, watermark, or sign-up. The practical limits are your browser's available memory and this tool's 50 MB, 50 megapixel, and 16,384 pixel-per-side safety limits.
How many PNG files can I convert?
You can convert one PNG at a time, with no daily quota. This focused workflow lets you choose the right quality and transparency background for each image instead of applying one setting blindly to a mixed batch.
What happens to a transparent PNG when it becomes JPG?
JPG has no alpha channel, so transparent pixels must be blended with a solid color. This converter fills the Canvas with your chosen background before drawing the PNG. Partially transparent edges blend into that color too, which helps avoid unwanted dark or white halos.
What JPEG quality should I choose?
Start around 85 for a photo or general web image, then inspect fine texture, gradients, and edges. Lower values often reduce the file size but add visible artifacts. Higher values preserve more detail but can produce a JPG that is as large as, or larger than, the PNG.
Does converting PNG to JPG reduce quality?
Yes. PNG uses lossless compression, while JPEG is lossy and discards some image detail during encoding. At a high quality setting the change may be subtle, especially for photographs, but repeated conversions and low quality settings can introduce blockiness, ringing, or blurred edges.
Will the JPG keep the same width and height?
Yes. This converter keeps the PNG's original pixel dimensions and does not resize or crop it. Only the file format, compression, metadata, and treatment of transparent pixels change. Use the related image resizer when you also need new dimensions.
