PROCESSED LOCALLY
⬡ zero uploads

Every PDF tool you need,
running inside your browser.

Compress, convert, merge, sign, redact and read scans. Choose a tool and open a file — it is processed on this device and never uploaded.

Why this is different

No document is uploaded. This can be independently verified.

Comparable services transmit your file to a server and undertake to delete it subsequently. PaperJET has no server to which a document could be sent: the tools are compiled to WebAssembly and execute within this browser tab, on your own device. Nothing is queued, nothing is capped, and the work continues if you go offline after the page has loaded.

To verify Load this page, disconnect from the network, and then compress a document. The operation completes as normal. No server-dependent service could do so.
No uploadThe file is read from local storage by the browser and does not leave it. No copy exists anywhere other than on your own device.
No account requiredNo registration, no email address and no consent banner. An account is optional and serves only to retain your preferences.
No limitsNo file size cap, no daily quota, no queue and no watermark applied to output. The only constraint is the memory of your device.
Established componentsBuilt on pdf-lib, pdf.js and Tesseract, the same libraries used across the industry, executed locally.

Questions

Frequently asked questions

Are documents uploaded to a server?

No. Every tool executes within your own browser using WebAssembly. The file is read from local storage by the browser and is not transmitted, so no server holds a copy of it. This may be verified by disconnecting from the network once the page has loaded; the tools continue to function normally.

Is PaperJET free to use?

Yes. All tools are provided free of charge, with no account required, no watermark applied and no file size limit.

Can a scanned PDF be processed?

Yes. The OCR tool reads the text from a scan and can return the same scan with an invisible text layer applied, so that the document appears unchanged while becoming searchable and available for copying.

Can a PDF be converted to Word or Excel?

Yes, where the PDF already contains text. Where the file is a scan, the OCR tool should be used instead; the interface will indicate which case applies.

Is there a file size limit?

No. As processing is performed on your own device rather than on a server, the constraint is the available memory of that device rather than an upload cap.

Convert JPG to PDF

Assembles photographs or scanned images into a single PDF, in the order you arrange them. Useful for turning a set of phone photographs of a document into something that can be filed or sent as one file — and because the assembly happens on your own device, photographs of personal paperwork are not handed to a conversion service to do it.

How to convert JPG to PDF

  1. Open the images. JPG and PNG are both accepted, and several can be added at once.
  2. Arrange them into the order you want. The list is the page order of the finished PDF.
  3. Convert, and save the PDF.
One image, one page

Each image becomes a page sized to it, so photographs of a document in portrait produce portrait pages without cropping or letterboxing.

Photographs of documents

If the result is meant to be searched rather than merely viewed, run OCR on it afterwards. That adds an invisible text layer so the pages can be searched and copied from, while still looking like the photographs they are.

Questions about converting images to PDF

Are my photographs uploaded?

No. The PDF is assembled in this browser tab from images read off your own device. Nothing is transmitted.

Can I combine several images into one PDF?

Yes, that is the usual use. Add as many as you like, arrange them, and they become the pages of a single document in that order.

Are PNG files accepted, or only JPG?

Both JPG and PNG are accepted, and they can be mixed within one document.

Will the images lose quality?

No. The images are placed into the PDF as they are rather than re-encoded, so the pages are as good as the photographs you supplied.
