LocalPDF vs Smallpdf vs iLovePDF
All three tools help users handle PDF files. The fundamental difference is how each handles your documents — whether they stay on your device or are uploaded to a server. This page compares their privacy models, workflows, and public security-related responses observed during an automated surface scan on 2026-07-08.
How this data was collected: Public HTTP response headers and browser cookies were collected via an automated surface scanner on the dates shown. This is not a full penetration test or vulnerability assessment. Headers, cookies, and site behaviour may change after the scan date. Always verify current practices directly.

Public HTTP security headers (observed 2026-07-08)
The table below shows which standard response headers were served by each site's homepage during a single automated request. These headers help browsers enforce security-related behaviour. Their presence or absence is a factual observation, not a determination of overall security posture.
| Header | LocalPDF | Smallpdf | iLovePDF |
|---|---|---|---|
Content-Security-Policy | Present — default-src 'self', frame-ancestors 'none', upgrade-insecure-requests | Not detected | Not detected |
Strict-Transport-Security | max-age=63072000 (2 years) | max-age=15552000 (180 days) | max-age=15552000 (180 days), includeSubDomains, preload |
X-Frame-Options | DENY | sameorigin | Not detected |
X-Content-Type-Options | nosniff | Not detected | Not detected |
Referrer-Policy | strict-origin-when-cross-origin | Not detected | Not detected |
Permissions-Policy | camera=(), microphone=(), geolocation=() | Not detected | Not detected |
Note: A Content-Security-Policy (CSP) helps limit which scripts and
resources a page can load. X-Frame-Options: DENY prevents clickjacking by
blocking the page from being embedded via iframe. X-Content-Type-Options: nosniff
reduces MIME confusion risks. Referrer-Policy controls what data is sent in
the Referer header during navigation.
Browser cookies observed (scanned 2026-07-08)
Cookies were collected from a fresh browser context without prior site interaction. Cookie counts and flags reflect a single scan pass — consent banners, logged-in states, or region may affect what cookies are set.
| Observation | LocalPDF | Smallpdf | iLovePDF |
|---|---|---|---|
| Cookies set on homepage | 4 (PostHog analytics, Google Analytics ×3) | 1 (_s.lt — session/cdn) | 1 (__cf_bm — Cloudflare bot management) |
| Cookies with Secure flag | PostHog cookie — yes; GA cookies — not set on homepage scan | _s.lt — yes | __cf_bm — yes |
| Cookies with HttpOnly flag | Not observed on homepage cookies | Not observed on _s.lt | __cf_bm — yes |
| Cookies with SameSite | Lax (PostHog, GA) | Strict | None |
| Notable pricing-page observations | No payment/session cookies on /pricing | Same 1 cookie | 2 cookies: __cf_bm + _csrf-ilovepdf (HttpOnly, Lax, without Secure flag) |
Note: The Secure flag instructs the browser to send the
cookie only over HTTPS. HttpOnly prevents JavaScript access to the cookie.
SameSite controls when the cookie is sent with cross-site requests.
These flags are considered good practices for session and CSRF protection cookies.
