Share Large Documents Without File Size Headaches

The 25 MB Problem

Email caps attachments at 25 MB. Google Drive warns you at 100 MB. WeTransfer and similar tools handle the transfer, but strip away everything that matters after delivery - who opened the file, which pages they read, whether they downloaded it.

For documents that fit in a few megabytes, this is fine. For the documents that actually drive business decisions - construction blueprints, engineering CAD exports, legal due diligence bundles, financial audit packages - it is not.

These files are large. And the tools built for sharing them were designed for small ones.

Why Business Documents Keep Getting Bigger

Document sizes have grown steadily across every industry that relies on professional file sharing:

Construction and engineering. Architectural drawings, site plans, and BIM exports routinely exceed standard upload limits. A single set of construction documents for a mid-size commercial project can contain hundreds of pages of technical drawings, specifications, and compliance certificates.

Legal due diligence. M&A transactions, regulatory filings, and litigation discovery produce document bundles measured in hundreds of megabytes. Law firms and corporate counsel need to share these with counterparties under strict access controls - not through a file transfer link that anyone can forward.

Financial audits. Annual audit packages combine financial statements, supporting schedules, tax documentation, and correspondence into single deliverables. Splitting these across multiple uploads breaks the audit trail and creates version confusion.

Real estate transactions. Property documentation - title searches, survey reports, environmental assessments, zoning records - adds up fast when a deal involves multiple parcels or jurisdictions.

Upload Once, Share with Controls

File transfer tools solve the size problem but create a new one: the file leaves your control the moment the recipient downloads it. There is no audit trail, no access revocation, no visibility into what happens next.

PaperLink handles large files the same way it handles any document. Upload a file - regardless of size - and the platform generates a secure, trackable link. The document stays on PaperLink's infrastructure. Your recipient views it through the browser-based document viewer.

Every sharing control applies to large files:

• Password protection - gate access behind a password
• Email verification - require the viewer to confirm their email before opening
• NDA and agreement gates - viewers sign before they can see the first page
• Expiration dates - links stop working after your deadline
• Download control - allow or block downloads per link
• Custom URLs - share from your own domain with custom URL slugs

The file size does not change what controls are available. A 300 MB construction package gets the same security options as a 2 MB proposal.

Page-by-Page Analytics on Every File

Most file transfer services tell you one thing: the file was downloaded. PaperLink tells you what happened after that.

Every shared document - including large ones - tracks:

• Who viewed it - email or name of each viewer
• When they viewed it - timestamps for every session
• Which pages they read - page-by-page engagement data
• How long they spent - time per page, total session duration
• Whether they downloaded it - if downloads were enabled
• What device they used - desktop, mobile, operating system

For a 200-page due diligence bundle, this means you know whether your counterparty reviewed the environmental assessment on page 147 or stopped at the executive summary. For construction documents, you know whether the contractor opened the structural drawings or only looked at the floor plans.

Data Rooms for Large Document Collections

Individual large files are one part of the equation. Many workflows require sharing entire collections - dozens or hundreds of documents organized by category.

PaperLink data rooms let you create structured folders of documents and share the entire collection under a single link. Each document within the data room supports the same analytics and access controls.

For due diligence, this means organizing documents by category - financial, legal, operational, compliance - and sharing the complete room with investors or counterparties. They navigate the folder structure in their browser. You see exactly which documents they opened and how thoroughly they reviewed each one.

No Compression, No Splitting, No Workarounds

The standard workaround for sharing large files through email or basic tools involves compressing files into ZIP archives, splitting documents across multiple uploads, or downgrading resolution to meet size limits.

Each workaround degrades the recipient's experience. Compressed archives require extraction. Split documents lose context. Downgraded resolution makes technical drawings unreadable.

PaperLink accepts large files as-is. Upload the original document at full resolution. The viewer renders it in the browser without requiring your recipient to download, extract, or reassemble anything.

Built for the Documents That Matter Most

Small files are easy to share. Every tool handles them. The documents that carry the highest stakes - the ones that close deals, pass audits, satisfy regulators, and move construction projects forward - are rarely small.

PaperLink handles large file uploads with the same analytics, security controls, and sharing features available for any document. No size-based feature degradation. No workarounds.
