Send Large PDFs Without WeTransfer or Dropbox

Published August 1, 2026 · 8 min read

Your PDF is 24 MB. Email won't take it. So you do what everyone does: upload it to WeTransfer, get a link, paste the link in an email. The recipient downloads it. Simple. Except now a copy of your document sits on WeTransfer's servers in the Netherlands (or Dropbox's in the US, or Google's in whatever region they choose). For a vacation photo album, fine. For a client contract, a legal brief, or a financial report, you just handed a third party your data. There are better options — and for 90% of “too large” PDFs, the best option is not a transfer service at all. It is compression.

The privacy problem with file transfer services

When you upload a file to WeTransfer, Dropbox, Google Drive, or any cloud sharing service, you are making a deliberate copy of your document on infrastructure you do not control. Specifically:

• WeTransfer stores your file for 7 days (free) or indefinitely (Pro). Files are stored on AWS infrastructure. WeTransfer staff can access files for support or legal compliance.
• Dropbox keeps your file until you delete it. Dropbox employees with legitimate business reasons can access content. Files are scanned for malware and DMCA violations.
• Google Drive scans content for abuse, malware, and illegal material. Automated systems process your file. It persists until you delete it.

None of these services are “evil” — they provide a legitimate service and are transparent about their practices. But “transparent” is not the same as “private.” If your document contains trade secrets, personal health information, attorney-client privileged material, or anything covered by NDA, a cloud upload creates a data exposure you did not need to accept.

Alternative 1: Compress the PDF to fit email (best for most cases)

Here is the thing most people miss: the average “too large” PDF is 10–30 MB. Email limits are 20–25 MB. The gap is small. A single pass through a compressor closes it entirely.

LoveMyFile's Compress PDF tool runs in your browser. Your file is never uploaded anywhere. The compression happens locally using JavaScript — you can watch your Network tab and confirm zero outgoing requests. A 24 MB scanned report typically becomes 3–5 MB, well under every email provider's limit.

This is the privacy-optimal solution: the file goes directly from your outbox to the recipient's inbox. No intermediary. No third-party copy. No expiration date. No link to manage.

Alternative 2: Split into parts

For documents that stay large even after compression (100+ page scans, portfolios with high-res images), split the PDF into logical sections and send them as separate emails. LoveMyFile's Split PDF tool extracts page ranges locally.

A 60 MB file split into four 15 MB parts, each compressed to ~3 MB, gives you four small attachments that sail through any email system. Label them “Part 1/4,” “Part 2/4,” etc. The recipient can reassemble them with the Merge PDF tool if they want a single file.

Alternative 3: Password-protect, then use cloud

If you genuinely need cloud storage (the file is 100+ MB and compression will not help), add a layer of protection first. Password-protect the PDF with strong encryption before uploading. LoveMyFile's Protect PDF tool applies AES-256 encryption locally. Then upload the encrypted file to whatever service you prefer.

Now the cloud provider stores an encrypted blob they cannot read. Send the password to the recipient through a separate channel (a phone call, a text message, a different email). This is meaningfully more private than uploading a plain PDF, though it is still less private than avoiding the cloud entirely.

Alternative 4: Self-hosted sharing

For organizations with strict data requirements, self-hosted file sharing (Nextcloud, Seafile, or a simple SFTP server) keeps files on infrastructure you control. This is the most private cloud option, but it requires setup, maintenance, and bandwidth. It makes sense for businesses that regularly share large files with clients; it is overkill for sending one contract to one person.

Honest comparison: when each option wins

When WeTransfer is genuinely the right call

To be fair to WeTransfer and similar services: they solve a real problem well. If you are sending a 2 GB video file, a 500 MB Photoshop archive, or any non-PDF format that does not benefit from compression, a file transfer service is the pragmatic choice. Their upload speeds are fast, the recipient experience is smooth (no account needed to download), and the free tier is generous.

The point is not “never use WeTransfer.” The point is: for a 20 MB PDF that compresses to 4 MB, using WeTransfer means you uploaded a file to a third party unnecessarily. The compression path is faster (no upload/download wait), more private (no third-party copy), and more reliable for the recipient (a real attachment, not a link that expires in 7 days).

The 90% rule

In our experience, roughly 90% of “file too large for email” situations involve PDFs in the 10–30 MB range. These are scanned documents, image-heavy reports, presentations exported as PDF, or multi-page forms with embedded photos. Every single one of these compresses to under 5 MB with acceptable quality.

That means 9 out of 10 times you reach for WeTransfer, you did not need it. A 10-second compression step would have let you send a normal email attachment — faster for you, simpler for the recipient, and with no copy of your document sitting on someone else's server.

Quick decision flowchart

1. 1Is it a PDF? If no, and it is over 25 MB, use a transfer service. If yes, continue.
2. 2Compress it. Is it now under 20 MB? Send via email. Done.
3. 3Still too large? Split into parts, compress each, send as multiple emails.
4. 4Genuinely cannot get under 20 MB (100+ pages, high-res photos)? Password-protect it, then use a cloud link. Send the password separately.

Most people stop at step 2. The entire process takes under a minute, requires no account, and keeps your document between you and the person you are sending it to.
