The workflow matches any other PDF site. What changes is where the work happens.
- 01
Pick a tool and add files
Drag files in or browse from your device. No account, no email, no waiting in a queue.
- 02
Adjust the options
Choose page ranges, quality, watermark text or where a signature goes. You can preview before committing.
- 03
Download the result
The new PDF is built in your browser and saved straight to your downloads folder.
What changes when nothing is uploaded
Most online PDF tools ask you to upload a file, process it on a server, and hand it back. That round trip is the part PDF Kept removes.
It matters most for contracts, medical records, payroll files and anything under an NDA — documents that should not sit in a third party’s storage while you wait.
| Feature | PDF Kept | Typical online tools |
|---|---|---|
| Where files are processed | In your browser | On their servers |
| Upload required | No, never | Yes, every file |
| Account | Not required | Often required for larger files |
| Task limits | No daily quota; 30 files and 500 MB per file | Daily caps and smaller file-size limits |
| Works offline | Yes, after first load | No |
| What is left on a server | Nothing | Files, until their retention policy clears them |
Built for documents you would rather not hand over
A browser tab is not a server. That distinction is the whole product.
Legal
Exhibits, discovery bundles and client agreements. Merge and redact page ranges without sending privileged material to a third party.
HR & recruiting
Offer letters and ID documents carry personal data. Split and sign them locally, then delete the working copies.
Finance
Statements, invoices and tax packets get combined and compressed for email — with no copy left in someone else’s storage.
Healthcare
Patient records and referrals are the last files that should be uploaded to a random website. Process them on the device.

Common questions
Short answers about privacy, limits and how the processing works.
Are my files really not uploaded?
Correct. PDF Kept has no backend for documents. Files are opened with JavaScript and WebAssembly inside your browser, and the output file is generated there too. You can check it yourself: open your browser’s Network tab while a tool runs and you will not see your document being uploaded.
Is it actually free?
Yes. The site is paid for by advertising. There is no paid tier, no watermark added to your output, and no daily task limit.
Do I need an account?
No. There is nothing to sign up for and nothing stored between visits. Close the tab and the working files are gone from memory.
What is the maximum file size?
500 MB per file and 30 files per run. Those are guard rails for the browser rather than a quota: there is nothing to buy to raise them. Below that ceiling, the practical limit is your device memory, and a very large scanned document can exhaust it.
Can I use the site offline?
After the page has loaded once, supported browsers can keep serving the tools from cache without a connection. Anything that is already loaded keeps working, which is another way to confirm nothing is processed remotely.
Does it work on mobile?
Yes, on current iOS and Android browsers. Small screens are fine for a handful of pages; for very large documents a desktop browser is more comfortable.
Is the Sign tool a legally binding digital signature?
It adds a visual electronic signature to the page — useful for internal forms and acknowledgements. It is not a certificate-based digital signature (PAdES), so it does not prove who signed. For contracts that require verified identity, use a dedicated e-signature service.
Your documents do not need a round trip.
