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.

Rotate a PDF

Corrects the orientation of pages that were scanned or saved sideways. The operation is entirely lossless: it records how each page should be displayed rather than redrawing it, so nothing whatever is degraded and the rotation can be undone later without cost.

How to rotate a PDF

  1. Open the PDF. Each page appears as a thumbnail.
  2. Rotate the pages that need it, or apply the same rotation to all of them.
  3. Save the result. The pages themselves are unchanged apart from the recorded orientation.
Genuinely lossless

Rotation sets a property on the page rather than re-rendering its contents. Text stays selectable, images are untouched and the file does not grow. This is not true of tools that rotate by re-drawing each page as an image.

Page by page, or all at once

A scan that fed through the machine sideways usually needs every page turned the same way; a document with one landscape table in it needs only that page. Both are handled.

Questions about rotating a PDF

Is the PDF uploaded to rotate it?

No. The rotation is applied in this browser tab and the document is never transmitted.

Does rotating reduce the quality of the pages?

No. The operation records the orientation the page should be displayed at rather than redrawing its contents, so nothing is re-encoded and no quality is lost.

Can I rotate only some of the pages?

Yes. Each page can be turned independently from its thumbnail, or one rotation can be applied to the whole document at once.

Why does my PDF still open sideways elsewhere?

A few older viewers ignore the rotation property and display the page as originally drawn. Saving from a current viewer, or any modern browser, honours it correctly.
