EditMyStuff vs Online Tools: Privacy-First File Processing
Most online file tools upload your documents to a server. EditMyStuff's file tools process them in your browser — no upload, no document tracking, no account. Here's why it matters.

When you upload a PDF to a "free online converter," where does it actually go? Onto someone else's server — to be processed, and often stored for a while, on infrastructure you can't see. For a holiday photo that might be fine. For a payslip, a signed contract, an ID scan, or a tax form, it isn't. EditMyStuff takes a different approach: the file tools run in your browser, so your files never leave your device.
Why privacy matters for files
Documents are dense with personal data — names, addresses, account numbers, salaries, signatures. Uploading them means trusting a third party's storage, retention policy, and security. Data breaches are routine, and "we delete after an hour" is a promise you can't verify. The safest file is the one that was never uploaded in the first place.
How most online tools work
The typical flow is: you select a file, it's uploaded to a server, processed there, and you download the result. That means:
- Your document sits on hardware you don't control.
- Retention is opaque — you rarely know how long a copy lingers.
- A large or sensitive file is now a copy outside your possession.
How EditMyStuff works
EditMyStuff's file tools run the processing client-side — in the JavaScript sandbox of your own browser tab. When you open a PDF in the editor, fill a form in the PDF Form Filler, or build a resume, the file is read into memory locally, edited locally, and exported locally. It is never sent over the network. Close the tab and it's gone from memory.
The exception is the clearly labelled AI features. When you use one, it sends only what that feature needs — usually text, sometimes an image you add, such as an architecture diagram in System Design or a screenshot for Design System's AI Vision — to an AI provider through our server. Each tool tells you when data leaves the tab.
Comparison at a glance
| Typical online tool | EditMyStuff's file tools | |
|---|---|---|
| File upload | Yes, to a server | No — stays in your browser |
| Account / sign-up | Often required | Not required |
| Data retention | Opaque | Nothing to retain |
| Tracking your documents | Common | None |
| Works offline | No | Partly — keeps working if your connection drops once your file is open |
| Cost | "Free" (you're the product) | Free file tools; AI features have free uses, then credits |
Security benefits
- No upload means no server-side breach can expose your file — there's no copy to breach.
- Using the file tools without an account means no credentials to leak and no profile tied to your documents.
- Local processing means predictable behaviour — what happens is what your device does, nothing more.
No document tracking
Because the file tools never send your files to us, there's nothing in them for us to read, sell, or profile. Google Analytics runs only if you allow it in Cookie settings, and never touches your documents. On a shared computer, finish your edit, download, and close the tab to clear the file from memory; clear the site's data too if you used the Form Filler or saved a signature.
Real use cases where this counts
- HR and finance handling payslips, offer letters and tax forms.
- Legal and healthcare documents that must not touch third-party servers.
- Anyone signing or redacting a contract or ID before sending it on.
- Students and jobseekers whose resumes and transcripts are their own business.

There's nothing to install, and the file tools need no account. Explore the tools and open any file tool — the file you work on stays exactly where it should: with you.
FAQs
Do you really not upload my files? Correct, for the file tools: editing and export happen in your browser, and the document never crosses the network. A file is only sent when you choose an AI feature that works on an image — adding an architecture image to System Design, for example — and that tool says so.
How do AI features fit in? They're clearly labelled and optional: the PDF Form Filler asks before it names the fields of a flat or scanned PDF with AI, and then sends the page's printed text, never your answers. When you trigger one, it sends only what that feature needs — usually text, sometimes an image you add — to an AI provider through our server, using your own API key if you've added one.
Is it free? The file tools are free. AI features include free AI requests every day, shared by all the AI tools (3 a day without an account, 15 signed in); after that each request needs a credit.
