How to Compress a PDF

Updated October 4, 2026

Compressing a PDF can reduce file size when an email attachment or upload has a size limit.

Step 1: Prepare the document

Use a compression setting appropriate for the document. Text-heavy files often compress differently from image-heavy scans, so review readability after compression.

Step 2: Review the result

Open the finished document and check that the content, page order, formatting and readability match what you expected.

Step 3: Keep an original copy

For important documents, keep the original file separately so you can recover it if you need to make another version later.

Frequently asked questions

Will every PDF behave the same way? Not always. PDFs can contain text, scanned images, forms, fonts and other elements that affect processing.

What should I do if the result looks wrong? Try another processing setting or workflow and compare the output with the original.
