Compress PDF
Compress PDF: prepare a smaller working PDF copy
Use Compress PDF to prepare a smaller working PDF copy. Try reducing a document’s file size for a destination with an attachment or upload allowance.
How to use Compress PDF
Select a PDF, adjust Scale and Quality, and select Submit. Inspect the resulting PDF and compare its file size with the original before downloading it.
Example and practical checks
Compare a representative file before and after processing, including a page with images and small text. Review every affected page, including page boundaries, text, graphics, and the final sequence. A small test document helps you spot a missing page or an unexpected layout change.
Review the generated document
This operation rebuilds each page as a JPEG image in a new PDF. Selectable text, links, forms, and other interactive or structural features may be lost. Keep the original if you need those features.
File size reduction varies with the source. Inspect readability, image detail, forms, and other features before replacing the original. Use the correct source document for the task. Confirm its filename and contents before processing, especially when several similar versions are available.
Common questions
Will every PDF become smaller?
No size reduction should be assumed in advance. Measure the actual output and check that it still meets your quality needs.
Which tools help with the next document step?
Use PDF page counter to inspect document length, Reorder PDF pages to adjust the sequence, or PDF viewer for a reading check. Work on a retained copy and review the result after each operation.
