The problem

Every time you use a free file converter, you're gambling with your data.

Free converters are a privacy nightmare

In 2025, the FBI issued a public warning: free online PDF converters are being used to distribute malware and steal sensitive data. That "free" tool could be the most expensive click your company ever makes.

637 tracking cookies. On one site.

A Reddit post exposing iLovePDF's 637 tracking cookies went viral with 19,600+ upvotes. Your file contents, metadata, and browsing behavior — packaged and sold to advertisers. And that's one of the "reputable" ones.

Your files sit on someone else's server

Every major converter — iLovePDF, Smallpdf, Convertio, CloudConvert — requires uploading your files to their cloud. That means your contracts, medical records, and financial statements pass through infrastructure you don't control.

One upload away from a compliance violation

If your team handles HIPAA-protected health records or GDPR-regulated personal data, uploading to a third-party converter without a BAA or DPA isn't just risky — it's a violation. Fines start at $100 per record.

How it works

Convert files in 3 steps. Zero data leaves your browser.

1

Drop your file in

Drag and drop any PDF, DOCX, image, spreadsheet, or presentation. No size limits on paid plans. No account required for your first conversion.

2

We process it locally

Our WebAssembly engine runs entirely in your browser tab. Your file is converted on your machine using your CPU. Nothing is transmitted, uploaded, or cached anywhere.

3

Download the result

Your converted file appears instantly. The original and converted files exist only in your browser memory — close the tab and they're gone. No traces. No server logs.

Features

Enterprise-grade security. Zero-effort setup.

Zero-Upload Architecture

Not "encrypted uploads." Not "files deleted after 24 hours." Literally zero data transmission. Our WASM engine processes files in your browser tab. There is no server to breach.

50+ Format Conversions

PDF to DOCX. PNG to SVG. HEIC to JPG. Excel to CSV. We support every format your team actually uses — without the format limitations of "free tier" competitors.

Batch Convert Entire Folders

Drop 100 files at once. Our engine processes them in parallel using Web Workers — converting your entire folder in the time it takes competitors to upload a single file.

Built-In OCR

Extract text from scanned PDFs and images — all locally. Perfect for legal teams digitizing case files or healthcare providers processing scanned intake forms.

Audit Logs for Compliance

Business plans include detailed conversion logs: who converted what, when, and which format — without storing file contents. The paper trail your compliance team needs.

Works Offline

After the first load, SecureConvert works without an internet connection. Convert sensitive documents on an air-gapped laptop. Perfect for classified environments or secure facilities.

"We switched our entire legal team to SecureConvert after the FBI warning about free PDF converters. The peace of mind alone is worth 10x the price."

Sarah M.

IT Director at a 200-person law firm

"I used to cringe every time a nurse uploaded patient intake forms to Smallpdf. With SecureConvert, I sleep at night knowing we're HIPAA compliant by architecture, not just by hope."

Dr. James K.

Chief Compliance Officer, Regional Health Network

"Our security audit flagged 14 different free converter tools employees were using. We replaced all of them with one SecureConvert Business license. Problem solved."

Raj P.

CISO at a fintech startup

FAQ

Frequently asked questions

We use WebAssembly (WASM) — a technology that lets us run our conversion engine directly in your browser. Think of it like installing a lightweight app that lives in your browser tab. Your files are processed using your computer's CPU and memory. Our servers deliver the application code, but your data never touches them.

Yes — by architecture, not just by policy. Since files never leave your device, there's no data transmission to secure, no server storage to encrypt, and no third-party processing to regulate. For HIPAA-covered entities, our Business plan includes a BAA. For GDPR, our architecture means we are never a data processor of your file contents — because we never receive them.

Nothing — because they never left your device. Both the original and converted files exist only in your browser's memory. Close the tab and they're gone. There are no server logs, no file caches, no "deleted after 24 hours" policies. There's nothing to delete because there's nothing to store.

For most files, it's faster. Cloud converters require uploading your file, waiting for server-side processing, then downloading the result. SecureConvert skips the upload and download entirely — conversion starts the instant you drop your file. For very large files (500MB+), performance depends on your device's hardware, but you'll typically see results in seconds.

Starter plans support 15+ common formats including PDF, DOCX, XLSX, PPTX, JPG, PNG, SVG, HEIC, and more. Professional and Business plans unlock 50+ formats including CAD files, ebook formats, raw image files, and specialized document types. We add new formats monthly.

Yes. SecureConvert works in any modern browser — Chrome, Firefox, Safari, Edge — on desktop, tablet, and mobile. WASM is supported on all major browsers and devices released since 2019.

SecureConvert works offline after the first load. Visit the site once while connected, and the WASM engine is cached locally. After that, you can convert files without any internet connection — perfect for classified environments, secure facilities, or anywhere connectivity is restricted.

Admins get a dashboard showing team usage, conversion activity logs (without file contents), and user management. SSO integration means your team authenticates through your existing identity provider. Audit logs capture who converted what format and when — giving compliance teams the paper trail they need without any data exposure.
