Edit a PDF without uploading it
Most “free PDF editors” send your file to their servers to process it. LocalSign doesn’t: it opens and edits your PDF entirely in your browser, so the document never leaves your device.
Why this is useful
PDFs you edit are often contracts, offer letters, invoices, or forms with names, addresses, and financial details. Uploading those to an unknown server is a real privacy exposure — you’re trusting a third party with the file and its contents. Editing in the browser removes that step entirely: there is no upload, no server-side copy, and nothing to delete later.
How to use it
- Open the editor and choose a PDF from your device.
- Add text, dates, an image, a signature, or shapes; drag and resize them.
- Use undo/redo, layers, and alignment to arrange your edits.
- Download the edited PDF — it was processed entirely in your browser.
Good to know
- Text is single- or explicit-multi-line (no automatic wrapping).
- Encrypted/password-protected PDFs may fail to open.
- Very large PDFs depend on your device’s memory.
FAQ
Is my PDF uploaded to a server?
No. The file is read and edited locally in your browser and is never uploaded.
Can I edit a PDF on my phone?
Yes — it’s mobile-responsive, though precise placement is easier on a desktop.
Does it work offline?
You can install LocalSign as a web app; editing still happens locally in the browser.
Privacy & honesty
Your documents stay on your device — LocalSign has no servers that receive your files. Signatures, stamps, highlights, shapes, and other annotations are visual changes created by you. LocalSign does not verify, certify, notarize, or legally validate documents.
