Large PDF files can be difficult to email or upload to websites with file-size limits. PDF compression reduces the document size so it is easier to share.
Why PDF files become large
High-resolution images, scanned pages and embedded fonts can increase PDF size. A document containing many photographs may be much larger than a text-only PDF.
Compress the PDF
Use a browser-based PDF compressor, upload the document and download the compressed copy. Compression settings can affect image quality, so choose a suitable balance for the purpose of the document.
Check quality after compression
Open the compressed PDF before sending it. Make sure text remains readable, images are clear enough for their purpose and no pages or important elements have been lost.
For official documents
If the PDF is being submitted to an employer, government portal, bank or other organization, check its file-size and format requirements before compression. Keep the original file as a backup.
