How to convert PNG to JPG online tutorial

As our site’s name and process detailed above suggests it, we work simultaneously with image and PDF formats. You first convert the PNG to the Portable Document Format (PDF) and then save it again to a JPG.

The best compression algorithm online


Smallpdf is an expert to many things, but our first core function was file compression (with our aptly titled name). The highest quality of documents will be retained as we remove repetitive patterns and strip down the file size of your images to its lowest. Other elements, such as your PNG images’ transparent background and color palettes, will be kept as close to its original form as possible.

The lossy compressed images that come out from the JPG converter can then be uploaded and shared online, with ease. It’s also useful if you wish to store these images on devices with limited storage capacities, such as older mobile devices or tablets.

If somehow the JPG file is still not small enough for your liking, we’d suggest to compress it further using the PDF compress tool while the PNG is in PDF format, before saving it as a JPEG image. Two modes of compression are available, ‘standard’ and ‘strong’ modes.


Compress images further (while in PDF mode)



PNG was created as an alternative to a then (and still is) popular image format - GIF and supports transparency within images. Photos, which are now widely created via mobile devices, are saved as PNG, which could get bulky. On the other hand, JPG similar to PDF in the sense that they were created to reduce the size of your photos smaller so that they could be shared easily. It’s up to you to keep images the original format, or to offset some of the quality for smaller sizes!

We make PNG and JPG easy


There are a handful of other types of images that Smalpdf supports, including GIF, TIFF, and even BMP images. The method to convert these images to JPG or PDF follows the same fashion (first save to PDF, and then to JPG). For the former, there are bonus options to split, merge, rotate, and even annotate your documents from various file types.
