Compress PDF

Choose size or clarity

Rebuild your PDF with JPEG-rendered pages at a selected high, medium, or low setting.

Choose how strongly to trade visual detail for a smaller file.

Reduce the size of a PDF for sharing

A smaller PDF can make a difference when a document is difficult to share through an email attachment, a portal, or a messaging app. Choose compression for a report, scan, or presentation copy when reduced storage or transfer size matters more than retaining every original PDF feature.

After you select high, medium, or low, the tool renders every page to JPEG and builds a new PDF from those images. Lower settings can reduce size further, but the resulting document is rasterized: text selection and search, links, and interactive form behavior may no longer remain.

Know what the new PDF leaves behind

Compression changes the PDF’s underlying content rather than preserving its original page objects. Because each page becomes an image, it is not a suitable choice when readers must copy text, search within the document, follow embedded links, or complete PDF form fields.

The pages are rendered and rebuilt inside the browser on the device you are using. The PDF is not sent to a server for compression, which keeps the document’s processing within your local browser session.

Frequently asked questions

Which setting should I choose for a document with small text?

Start with high when the PDF contains small type or detailed images and you want a more conservative tradeoff. Medium or low may make a smaller file, but they also reduce visual detail because pages are converted to JPEG. Review the compressed copy before using it for a purpose where legibility matters.

Will the compressed PDF keep text, links, and forms usable?

No. This process rebuilds all pages as images in a new PDF. That rasterization can remove selectable and searchable text, hyperlinks, and interactive form behavior. Keep the original if those capabilities are required, or if you need to preserve the document’s existing PDF structure.
