TL;DR

Four things to know before you read the rest.

Most big PDF tools are cloud services

Smallpdf, iLovePDF, Adobe Acrobat Online — you upload, their server edits, you download.

pdfed is different architecturally

Every edit runs locally in your browser. Your file never leaves your device.

Sensitive docs? Check architecture first

Contracts, medical, legal, tax, HR — the upload-vs-local question matters more than feature lists.

Need deep enterprise features?

Adobe Acrobat still wins on certified redaction, OCR depth, and compliance workflows.

Why “local vs. cloud” is the question that matters

Most browser-based PDF editors are thin UIs on top of a cloud service. That architecture is fine for a lot of use cases — but it has real consequences.

Cloud tools

Your file travels to a server

  • File uploaded, processed, sent back. They hold it during that window.
  • You rely on their retention policy. Policies change, companies get acquired.
  • Offline? Bad wifi? No editing.
  • Per-edit server cost is why free tiers exist — with daily caps and paywalls.
pdfed (local)

Your browser does the work

  • The editing engine ships inside the extension. No server to upload to.
  • No retention policy question — we never received your file in the first place.
  • Works offline. If your browser is open, pdfed works.
  • No per-edit cost = core features can stay free without caps.

FAQ

Questions people actually ask before switching tools.

Does pdfed do everything the bigger tools do?

No. pdfed is focused on in-browser editing, signing, redaction, and annotation. It doesn’t try to replace enterprise features like certified redaction, advanced OCR, or multi-party e-signature workflows.

Is cloud processing inherently bad?

No. For non-sensitive documents, cloud tools are fine and often more featureful. The question is: do you know what’s getting uploaded, and do you care? For sensitive files, caring is the correct default.

Does pdfed have a paid tier?

Core features are free. Advanced features may be added as premium options later; existing free features will remain free.

How do I verify pdfed doesn’t upload my files?

Open DevTools → Network tab → start editing a PDF. You’ll see no outbound request carrying the document. You can also read the extension’s requested permissions in the Chrome Web Store listing.
