Convert PNG to JPG Online for Free

Even with the abundance of image formats out there, PNG and JPG both lead as the two most popular image formats. PNG files accommodate every individual pixel in your photos, making them high-quality but also quite large images. JPGs, on the other hand, are compressed images, which is the go-to option for file sharing. With our handy file converters, you can quickly change PNG to JPG images in a few clicks.

How to Convert PNG to JPG Online

1. Go to our all-in-one image converter.
2. Drag the PNG in and first create a PDF.
3. Click on “Export As” and choose “Image.”
4. Choose “Convert entire pages.”
5. Download your new JPG image.

At Smallpdf, the PDF format is the key to success. All our conversions use this format as a bridge to help you get things done. As you can see above, turning a PNG into a JPG is no different: You first convert the PNG to the Portable Document Format (PDF) and then save it again to a JPG.

Why Convert PNG to JPG

Converting your PNG files to JPG format offers several benefits that make file sharing and storage much easier. The main advantage? Significantly smaller file sizes. JPG uses lossy compression (which removes some image data to reduce file size) to create files that are typically 50-80% smaller than their PNG counterparts.

Here are the key reasons you might want to convert:

• Faster uploads and downloads: Smaller files mean quicker sharing via email, social media, or cloud storage.
• Better web performance: JPG images load faster on websites, improving user experience.
• Universal compatibility: JPG works across all devices, browsers, and platforms without issues.
• Print-ready format: Most professional printing services prefer JPG for photos.
• Storage savings: Keep more images on your device or in your cloud storage.

PNG vs. JPG: What's the Difference?

PNG was created as an alternative to the popular image format GIF and supports transparency within images. Photos, which are now widely created via mobile devices, are typically saved as PNG. That means that they can take up quite a bit of space on your mobile, your PC, or your cloud storage. On the other hand, JPG is similar to PDF in the sense that it was created to reduce the size of your files so that you can share them more easily.

Here's a quick breakdown of the key differences:

• PNG: Lossless compression, supports transparency (alpha channel), larger file sizes, best for graphics with text or sharp edges
• JPG: Lossy compression, no transparency support, much smaller file sizes, ideal for photos and complex images

Best Uses for JPG After Converting

Once you've converted your PNG to JPG, you'll find the new format works perfectly for a variety of everyday uses. JPG files are particularly good for:

• Social media posts - Instagram, Facebook, and X (formerly Twitter) all prefer JPG for faster loading
• Website images - Improve your site's page load speed with smaller image files
• Email attachments - Stay under size limits while maintaining good image quality
• Digital photo printing - Most print services work best with JPG format
• Mobile device storage - Save space on your phone or tablet
• Professional portfolios - Share high-quality work samples without huge file sizes

High-Quality JPGs with Smart Compression

Smallpdf's original core focus was file compression (hint: it's in the name). We eliminate repetitive patterns, reducing the file size of your images to the smallest possible size while maintaining the highest quality. That means things like your PNG images' transparent background and color palettes are kept as close to their original form as possible.

You can upload and share the lossy compressed images that come out from the JPG converter online with ease. It's also a great format for storing these images on devices with limited storage capacities, such as older mobile devices or tablets.

If your JPG file still isn’t small enough, try compressing it further using the PDF compression tool while the file is in PDF format before saving it as a JPEG image. Two modes of compression are available: basic and strong.
