In short
Personal Gmail accounts turn attachments over 25MB into Drive links and Outlook lists 20MB, so a large report or scan needs another route. Hosting the PDF as a link sidesteps the limit, and the recipient opens it in the browser with nothing to download.
Email caps the size of every message. Google's help pages give 25MB for personal Gmail accounts and leave work and school accounts to the limit their Workspace administrator sets. Microsoft's help pages list 20MB as the email size limit for internet accounts in Outlook and a 10MB default for Exchange accounts, and that figure counts the message as well as the attachment. A proposal with embedded images, a scanned contract or a print-ready PDF can pass all of these limits without trying.
Why the usual workarounds add friction
Each usual workaround has a catch. When an attachment goes over the limit, Gmail swaps it for a Google Drive link, and Google's help page says Gmail lets you grant the recipient access before sending, so who can open the file depends on Drive's sharing settings. On WeTransfer's Free and Starter plans a transfer can stay online for up to 3 days, according to its help center (updated 29 May 2026). Compressing the PDF until it fits usually costs image quality, and the images are often the reason the PDF is large.
Host the PDF as a link instead
Hosting the file as a link takes the size limit out of the message. Drop the PDF on NudgeHost, copy the address it returns and paste that into your email. The recipient clicks and reads the document in the browser's own PDF viewer at full quality. A message that carries a link stays small however large the PDF is.
How large a file you can host
The free plan takes files up to 25MB, which covers most reports and scanned documents, and keeps 10 links live at once. The Pro upgrade costs $12 a month and raises the ceiling to 250MB, enough for a high-resolution print file or a long scanned dossier.
No plan meters visitors, so a link opened by a whole hiring committee keeps working. Some hosts cap the number of views a link can serve, which is the opposite of what you want when a document is doing its job.
Compress or bundle if you need to
A PDF is often large because of the images inside it, and shrinking them trades quality for size. Our glossary entry on file compression explains that trade-off. Compression is optional, because the link means you never have to shrink a file just to send it.
When the PDF travels with a cover letter, an appendix or a spreadsheet, you can put the files in a ZIP and send one link. A ZIP without an index.html is stored as a plain file, so the recipient downloads the archive from the file's download page.
Keep control after you send it
Hosting gives you control after sending, which an attachment never does. Any plan can put an expiry date on a link, and after that date visitors see a page saying it has expired. Pro and Studio add a password that visitors enter before the file opens. Deleting the file in your dashboard stops the link opening.
The use case page on sending a large PDF without email covers expiry and passwords in more detail. Your dashboard also shows how many times the link was opened, so you know when the document has been read.
