When this page helps

Use this page when you need Compress PDF to 1MB Online for a form, portal, or email attachment. UnderByte lets you aim at the limit directly instead of guessing export settings over and over.

PDFs with scans and photos usually shrink more than text-heavy PDFs. If you are still over 1 MB, removing extra pages or rescanning in grayscale usually helps more than repeated compression passes.
