Every feature earns its place. Nothing you'd pay for and nothing you'd miss.
Broken refs, auto-patched
“Save Page As” exports lose their chart and map libraries. We repoint the ones we know — Chart.js, D3, Leaflet, Plotly — to a CDN so the report still renders.
./chart.js → CDNLinks don't expire
No free-trial countdown, no takedown clock. Once it's up, it stays up — even after you close the tab.
TTL: foreverSealed in a sandbox
Your scripts and styles run — but inside a locked-down sandbox that can't read DropDoc's cookies, storage, or other reports. PDFs open straight in the browser's own viewer.
CSP: sandboxUnguessable slugs
Links are 8-character random ids — URL-safe, not indexed, not listed. Shareable means shareable on purpose.

HTML or PDF, no chrome, no banner, no watermark. The page your recipient opens is the page you built.

Drop
Drag an
.htmlor.pdffile onto the page, or click to browse. Single-file HTML and PDFs up to 3.5 MB. - 02
Sanitize
In HTML, dangerous markup and iframes get stripped and scripts run sealed in a sandbox; everything visual — styles, fonts, SVGs — stays intact. PDFs are verified and stored byte-for-byte.

You get a stable URL at
dropdoc.sh/r/<slug>. Paste it, print it, or text it to your client.
Things worth asking.
Is it really free?+
Yes. No card, no account, no paywall. If DropDoc saves you a minute, tips at s3labs.com keep it running — but nothing is gated.
Do links expire?+
No. Once a report is live, the URL is stable. We don't purge, we don't email you a renewal reminder, we don't run a free-trial timer.
Can I password-protect a report?+
Not yet. Slugs are random 8-character URL-safe ids — unguessable, not indexed — which covers most casual sharing. Password protection is on the roadmap.
What happens to scripts in my HTML?+
They run — but inside a locked-down sandbox with no access to DropDoc's cookies, storage, or other reports. We remove <iframe> and other risky markup at upload; styles, fonts, images, and SVG render exactly as designed.
Can I upload PDFs?+
Yes. A .pdf gets the same treatment as an .html file: same drop, same 8-character link, same 3.5MB ceiling. We check the file really is a PDF, store it byte-for-byte, and serve it so it opens in the browser's built-in viewer — your client can read, print, or save it without downloading anything first.
Can I use a custom domain?+
Not today. We might offer a one-time-purchase custom-subdomain tier later. No subscriptions, ever.
Who made this?+
S3 Labs — a tiny studio building simple, inexpensive, useful software. Everything we ship is free or one-time-purchase. Nothing recurring.
