Compress PDF

How this PDF compression works

Choose a PDF, then select render scale and JPEG quality before downloading. A lower scale creates fewer pixels per page; lower JPEG quality saves more space but can make small text and diagrams harder to read. Start with the preset values, then compare the downloaded copy with the original.

When is it useful?

A scanned document with large page images may become smaller. A PDF made mostly of selectable text, drawings or already compressed images can become larger. For example, a sharp, text-based one-page form can lose clarity when turned into an image.

Keep your original PDF. This process converts every page to an image. Selectable text, search, links, forms and accessibility structure are lost in the output. Open the downloaded file and check its size, page count and readability before sharing it.
