How to reduce a PDF for email
To send a PDF, you need to meet the destination limit without making the document unreadable. User PDF offers compression modes but does not promise an exact final size in bytes.
Steps and checks
- Check the form or email size limit and the original PDF size. Keep a copy before processing.
- In Compress PDF, start with Balanced. This mode recompresses data without turning all pages into images.
- Download the result and check its size, small text, logos, and barcodes on representative pages.
- If the file is still too large, consider Smallest size. This mode rasterizes pages: use it only if losing searchable text and other features is acceptable.
Can I reach 1 MB?
It depends on the original size, page count, images, and required readability. The system has no field that guarantees 1 MB. Compare the output against the destination actual limit; MB and MiB may use different byte counts. A PDF extension alone does not mean a file fits.
Why does a PDF barely shrink?
Mostly text-based or already optimized files may have little room for reduction. Repeating compression does not guarantee improvement and can reduce quality when rasterizing. Compare modes starting from the original instead of repeatedly recompressing the same copy.
What changes in Smallest size mode?
Pages become images. They may remain readable, but text selection and search may stop working. Also check links, forms, and fine details. If those features are required, use a conservative mode or another delivery method.
Alternatives when the file is still too large
If the recipient allows it, split the document into ranges or remove genuinely unnecessary pages with Organize pages. Do not remove information the recipient requires. Compression, splitting, and organization are different tasks and consume separate uses; the free allowance is 5 per IP daily.
