Best Free PDF Compressors - FAQs

How do I compress a PDF for high quality?

The higher the compression level, the lower the output quality of the content in your PDF. Therefore, if you require high-quality output from your PDF size compressor, it's best to choose the lowest compression level available. This approach can be used when you have images that need to be printed in hard copy or displayed on a large screen since their resolutions will be kept as close to the original as possible. In HiPDF and PDFelement, you can try the Low or Medium setting to see which is more suitable for your specific use.

Is it safe to use a free PDF compressor?

Absolutely! Just make sure that the software you download is from a reliable source or has been checked for malware. Check to see if there's a padlock symbol on the website to make sure the site is secure. Additionally, you can look for online reviews of the product before you download it. If you're searching for an open source PDF compressor, make sure it is a stable version.
