Comparison
DockDocs vs Smallpdf vs iLovePDF: how each handles your files
The core difference isn't features — it's where your file is processed. Smallpdf and iLovePDF are server-based: your file is uploaded, processed, encrypted in transit, and auto-deleted after a set time. DockDocs' client-side tools are different — the file is processed in your browser and never uploaded at all, which you can confirm yourself in DevTools. Both can be reasonable; the distinction is whether you have to trust a deletion policy or can verify that nothing was sent.

File-handling comparison
Verified facts, as of 2026-06-22 — policies may change.
| DockDocs | Smallpdf | iLovePDF | |
|---|---|---|---|
| Where files are processed | Client-side tools run in your browser — file never uploaded (0-byte upload, verifiable in DevTools). AI features send only extracted text, not the file. | “a secure tunnel between your device and our servers” [source ↗] | “While your files are in our servers, they are strictly secured” [source ↗] |
| File deletion | Client-side tools upload nothing, so there is nothing to delete. (AI: the text isn't retained by DockDocs; it does pass through a model provider.) | “Files are permanently removed from our servers after one hour of processing” [source ↗] | “automatically and permanently deleted within two hours of being processed (signed eSign docs kept up to 5 years)” [source ↗] |
| Encryption in transit | Client-side tools transfer no file at all. AI text is sent over HTTPS. | “256-bit TLS encryption” [source ↗] | “to protect your data, both in transit and at rest (plus end-to-end encryption)” [source ↗] |
| Third-party certification | None claimed — privacy is self-verifiable in your browser (DevTools) rather than relying on a certificate. | “ISO 27001 certified · GDPR and CCPA compliant” [source ↗] | “ISO/IEC 27001:2017 certification · fully GDPR compliant” [source ↗] |
| Pricing | Client-side PDF tools free (no account, no watermark); AI/Pro paid. | Free tier + paid plans (see smallpdf.com/pricing) | Free tier + paid plans (see ilovepdf.com/pricing) |
What the difference actually means
Smallpdf and iLovePDF both encrypt uploads and delete files on a timer, and iLovePDF states plainly that “iLovePDF does not - and will never - access, use, or analyse any content which you process with our tools.” That's a reasonable, privacy-respecting server model — but it still asks you to trust that the upload is handled and deleted as described.
DockDocs' client-side tools remove the need to trust that at all: if the file is never uploaded, there's no deletion policy to rely on and nothing stored on a server to begin with. It's not that a server model is “bad” — it's that a client-side model is verifiable: you can watch the upload not happen.
How to verify it yourself
Open any tool's page, open DevTools → Network (F12), and run it on a file. A server tool shows a large outbound request carrying your file; a client-side tool shows no file upload. You don't have to take anyone's word for it — including ours.
An honest note on AI
For AI features specifically (chat, summarize, extract), no tool can be fully zero-data — the text has to reach a model to get an answer. DockDocs' approach is to send only the extracted text, not the file, and not retain it on DockDocs servers, with the honest caveat that the text passes through a model provider. See “Can AI read my PDF without storing it?”
Does Smallpdf upload my files to its servers?+
Yes. Smallpdf is server-based — your file is uploaded over an encrypted connection (“a secure tunnel between your device and our servers”), processed, and, per Smallpdf, “permanently removed from our servers after one hour of processing” (as of 2026-06-22).
Does iLovePDF upload my files to its servers?+
Yes. iLovePDF processes files on its servers (“While your files are in our servers…”) and states they are “automatically and permanently deleted within two hours of being processed.” iLovePDF also states it does “not - and will never - access, use, or analyse any content” you process (as of 2026-06-22).
How is DockDocs different?+
DockDocs' client-side PDF tools process files in your browser and don't upload them at all — a 0-byte file upload you can confirm in DevTools → Network. There's no server copy to delete because the file never left your device. AI features send only the extracted text, not the file.
Which is the most private?+
It depends what you mean. Smallpdf and iLovePDF encrypt and auto-delete uploads — a model you trust. DockDocs' client-side tools don't upload the file at all — a model you can verify. For tasks that can run in the browser, “never uploaded” is the stronger guarantee because it's checkable.
Can I verify these claims myself?+
Yes. Open DevTools → Network (F12) and run a tool: if your file is uploaded you'll see it; if not, it stayed on your device. The competitor quotes here link to each company's own pages so you can read the current terms.
