How to reduce the weight of a PDF before sending it
A PDF may be too heavy to attach to an email or upload to a form. The size depends on images, fonts, scans, and internal content. Before optimizing, save a copy of the original and define the size limit you need to reach.
What usually increases the size of a PDF
Photographs and scanned pages usually occupy more space than vector text. Embedded fonts, repeated images, and other document resources may also influence the size.
Reducing the weight may involve a loss of quality. If the document contains seals, signatures, or small text, verify that they remain legible after optimizing.
How to evaluate the result
Don't rely solely on the kilobyte count. Open the file, enlarge small text pages, and compare images and graphics with the original.
If the document must meet a specific limit, review the final size in the file properties before uploading.
Common questions
Does compression always reduce the size?
No. Some PDFs are already optimized or contain elements that cannot be reduced significantly.
Can I compress without losing quality?
It depends on the content and method. Compare the exported file and don't use a degraded version for documents requiring high legibility.
