Reduce PDF file size online, quickly and easy

PDF is one of the most used file formats worldwide for saving and distributing information online. PDFs may contain text, images, videos, annotations, forms, layers and other types, which increase the size, and make it difficult to access, share or store.

When this is the case, you should rely on a high-quality PDF compression tool, which will reduce the file size effectively, yet keep the quality. Compressed PDF can be easily attached and send via email, because it's small in size and doesn’t exceed the limit that most e-mail providers have for attachments.

Compressing PDFs is also useful when publishing the files on a website. It saves server resources and does not overwhelm users' bandwidth.

In general, PDFs with graphics and scanned documents are large in size because of the DPI (dots per inch), and most scanners produce a decent image at 300 dots pet inch. To make the PDF lighter, use the PDF compressor and choose low or high compression depending on your preferences and needs.

With this PDF compressor, you can cut between 10% and 95% of the size of original PDF's size, and quickly prepare it for easy sharing.
