What to do first

  1. Make a copy of the original file.
  2. Compress the copy, not the original.
  3. Open the smaller file and check that it still looks right.
  4. Send the smaller copy and keep the original until the receiver confirms it works.

What this page is for

Reduce PDF Size Online helps when the file is blocking an email, upload, or Gmail attachment. The aim is a smaller PDF that opens normally and still looks right.

For email, a practical target is usually under 20-25 MB. Smaller targets such as 1 MB, 500 KB, or 100 KB may need stronger compression and closer checking.

How to make it smaller

  • Check the current PDF size first.
  • If the file is scanned, reduce image resolution before touching text quality.
  • Keep text readable and forms/signatures intact.
  • Try a medium compression setting first, then compare the result.
  • Send the smaller PDF only after opening it and checking the important pages.

What to watch before sending

  • The smaller file should open on another device or browser.
  • The important text, faces, signatures, charts, or product details should still be clear.
  • The file name and format should still make sense to the person receiving it.
  • If the target is a smaller file, check the final size before sending.

When Devenia should handle it

For difficult PDFs, scans, forms, or files that must stay sharp, Devenia can prepare a smaller copy and check the result manually.

This is separate from the guide. The page should still help you understand the job even if you do not ask Devenia to do it.
