# PDF to CDN

> Upload PDF files via dashboard or API. Get a public CDN link for invoices, reports, and docs. Cloudflare edge + free plan.

Upload a PDF and get a public CDN link for invoices, reports, proposals, and contracts. The file is served with Content-Type application/pdf, so most browsers open it inline or offer a download.

## How PDF upload works

From PDF file to shareable CDN link in seconds.

- Drop or select a PDF — try it without signing up; guest uploads support PDFs up to 16 MB.
- Get your CDN URL instantly — every upload returns a public URL served from Cloudflare's global edge.
- Share or embed the link — send the URL in email, Slack, or CRM fields.
- Automate with the API — POST the same file from curl, n8n, Zapier, or your backend.

## Upload PDFs via API

One POST request — get a public PDF URL in the response.

- POST multipart/form-data to https://api.droptocdn.com/v1/files with an Authorization: Bearer dtc_… header.
- The response returns id, url, expires_at, size, mime_type, and original_name.
- Embed the link with an iframe, or link to it with an anchor tag.

## PDF CDN use cases

Where teams use PDF-to-CDN workflows.

- Invoices and reports: generate a PDF in your app or accounting tool, upload it, and email customers a stable CDN link.
- Sales and proposals: host pitch decks, one-pagers, or signed contracts with a public URL you can paste anywhere.
- Workflow automation: export a PDF from n8n or another step, upload, and pass the link to the next system.

## PDF upload FAQ

### Are only PDF files supported?

This page focuses on PDF uploads (application/pdf). Drop to CDN accepts any file type via the same API — see the homepage or other use-case pages for images and videos.

### Can people view the PDF in the browser?

Yes. Most browsers open PDF URLs inline or offer a download. The file is served with Content-Type application/pdf from the CDN.

### Do you convert or compress PDFs?

No — PDFs are stored and served exactly as uploaded. Optimize or merge files before upload if needed.
