About the JPG to PNG Converter
The JPG to PNG Converter turns JPEG (JPG) images into Portable Network Graphics (PNG) files right inside your web browser. Convert to PNG when you need lossless quality for further editing, want to add transparency later, or an upload form requires PNG.
JPG (or JPEG) is the most widely used photo format in the world. It uses lossy compression to keep photographs small, which makes it perfect for cameras, websites and messaging, but it cannot store transparent areas and loses a little quality every time it is re-saved.
PNG is a lossless format that preserves every pixel exactly and supports full transparency. It is ideal for logos, icons, screenshots, illustrations and images with text, although photos saved as PNG are usually much larger than JPG.
PNG is lossless, so the converted file keeps every pixel of the decoded JPG image without adding any new compression artifacts. JPG images have no transparency, so the result looks exactly like the original. You can convert dozens of images at once, optionally limit the maximum width to shrink large photos, and download everything as a single ZIP file. Because the conversion runs locally on your device, your pictures are never uploaded to a server.
When converting JPG to PNG makes sense
- A site or app accepts only PNG, for example some icon uploads, sticker makers or game mods.
- You will edit the image several times. PNG does not lose quality when saved again, while a JPG loses a little each time.
- You want to add transparency later in a design program. Converting to PNG first gives you a format that can hold it.
What it will not do
- It does not improve quality. Any blur or blockiness already in the JPG stays.
- It does not remove the background. For a transparent cut-out, use the Background Remover.
- The PNG is usually 3–6 times larger than the JPG for a photo. That is normal, because PNG stores every pixel exactly.
If you only need a smaller or resized file, keep it as JPG and use the JPG Compressor instead.
How to use the JPG to PNG Converter
- Drop your JPG files into the upload area, click to browse, or paste an image.
- Adjust the quality or maximum width if needed.
- Wait a moment while each image is converted to PNG on your device.
- Download files individually or click Download all (ZIP).
Frequently asked questions
Will converting JPG to PNG reduce quality?
PNG is lossless, so the converted file keeps every pixel of the decoded JPG image without adding any new compression artifacts.
What happens to transparent backgrounds?
JPG images have no transparency, so the result looks exactly like the original.
Can I convert many images at once?
Yes. Add as many files as you want; they are converted one after another and can be downloaded together as a ZIP archive.
Are my images uploaded?
No. Conversion happens entirely in your browser using the HTML5 canvas, so your files never leave your device.
