FAQ
Does Gmail compress PDF attachments?▾
No, Gmail does not compress PDF attachments. It sends the exact file you attach. If your PDF exceeds 25MB, Gmail offers to share it via Google Drive instead, which requires the recipient to click a link. Pre-compressing your PDF ensures it sends as a direct attachment.
What about Google Workspace limits?▾
Google Workspace (formerly G Suite) uses the same 25MB attachment limit as personal Gmail. However, some organizations may set lower limits through admin policies. This preset creates files well under 25MB to work with any configuration.
Can I compress a PDF directly in Gmail?▾
Gmail doesn't have built-in PDF compression. You need to compress the file before attaching it. PDFlys processes your PDF entirely in your browser — compress it here, then attach the smaller version to your Gmail message.
