It’s important to note that Strong compression can visibly reduce the resolution of your image; because of that, this mode isn’t necessarily the best choice for serious design work. On the other hand, it’s perfect for situations where small file sizes are more important than image quality.

Along with that, Strong compression is available exclusively to people using paid Smallpdf plans like Smallpdf Pro. However, there’s no reason to worry if you don’t already have this subscription—you can give Strong compression and other Pro-exclusive capabilities a spin with our seven-day free trial!

Compressing PNGs and other files is one of Smallpdf’s most popular features, but this is far from the only way we help the people who use our site. Along with that, we offer helpful tools such as:

You’ve already heard that Smallpdf can turn PDF files into JPG images, but did you know we can also handle the opposite process? If you want to turn your PDF document into a JPG, just put it into our JPG to PDF converter.

When you’re sending a sensitive document to someone else, security is always a concern—especially if you want to prevent people from editing these files. With our Flatten PDF tool, you can irreversibly embed your PDF’s content into this document.

If you’re a freelancer or business owner, you know collecting contract signatures can be a pain. Fortunately, Smallpdf’s eSign feature makes it easier than ever to manage contracts—and to get signatures in ± 24 hours.

Do you have multiple PDF files that would be more convenient to work with as a single document? If so, the Merge PDF tool can combine your PDFs into one file.

In addition to tools like these, Smallpdf has added several AI-powered PDF tools to our feature lineup. That includes our Translate PDF tool, which can instantly generate translated summaries or full translations of your documents.

Are you a professional designer looking to create smaller versions of your work, or someone who simply wants to cut down on an image’s file size? Either way, converting and compressing PNG images is a great way to make these files more manageable. Fortunately, it shouldn’t take more than a few moments to reduce PNG file size when you know how to make a PNG smaller with Smallpdf.

Since Smallpdf is a cloud-based service, you can compress PNG files anywhere you can open a web browser. Better yet, you’ll have the ability to access our tools for free—no account required. Find out what we can do for you by diving into our complete selection of features today!
