Add your PNG files
Drop PNG images onto the upload area, click anywhere in it to browse, or paste an image from your clipboard.
IMAGE CONVERTER
Convert PNG images to JPG right in your browser. Control JPEG quality, choose how transparency is filled, and download one image or a whole batch.
Higher quality preserves more detail but usually creates a larger file.
JPG cannot store transparency. Transparent pixels are flattened onto this color.
Optional downscale only. Images are never enlarged.

HOW TO USE
Drop PNG images onto the upload area, click anywhere in it to browse, or paste an image from your clipboard.
Set JPEG quality, choose the color that should replace transparency, and optionally reduce large dimensions.
Convert locally, inspect each preview and file size, then download individual JPGs or the full batch as a ZIP.
Key Features
Queue up to 30 PNG images and convert them together instead of repeating the same steps one file at a time.
Choose JPEG quality from 40% to 100% and reconvert the batch whenever you want a different size/detail balance.
Pick the exact solid background used for transparent or semi-transparent PNG pixels before JPEG encoding.
Image decoding, compositing and JPEG encoding happen in your browser rather than through a conversion upload server.
See real input and output bytes for each image. The tool does not pretend every JPG will be smaller than its PNG.
Download converted files one by one or package all successful JPG results into a single locally generated ZIP.
FORMAT GUIDANCE
JPG is usually a better fit for photographs and continuous-tone images when file size matters and transparency is not required. PNG remains better for logos, icons, screenshots with crisp text, and artwork that must preserve a transparent background.
If your goal is only to make an image smaller while keeping its original format, Motricialy's Image Compressor is a more direct workflow. If you need to change dimensions instead, use the Image Resizer.
JPEG uses lossy compression, so fine edges and text can soften at lower quality values. For important images, review the preview before downloading and keep the original PNG as your source copy.
FAQ
JPG does not support transparency. Motricialy paints your chosen background color first, then draws the PNG over it so transparent and semi-transparent pixels are flattened deliberately rather than turning into an unexpected black background.
No. Photographic PNGs often shrink substantially as JPG, but small graphics and sharp screenshots can sometimes become similar in size or even larger. The converter shows the actual output bytes instead of assuming a saving.
No image upload is required for the conversion itself. Decoding and JPEG encoding run locally in your browser. If you only need compression without changing format, the Image Compressor may be a better fit.
JPEG is a lossy format, so conversion can discard some detail. Use a higher quality setting for text-heavy or detailed images, and inspect the preview before you download.
Yes. The optional maximum dimension setting can downscale a large image while preserving its aspect ratio. It never enlarges smaller images. For more precise resizing, use Motricialy's Image Resizer.
