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 PDF to JPG

Renders each page of a document as a separate JPG image and returns them together as a zip archive. The rendering is performed by this browser on your own device, so a document being turned into images for a presentation or a listing does not pass through a conversion service on the way.

How to convert PDF to JPG

  1. Open the PDF.
  2. Choose the resolution. 150 DPI suits reading on screen; 300 DPI is the sensible choice if the images will be printed.
  3. Convert, and save the zip archive. It contains one image per page.
Resolution is a real trade

Higher DPI means sharper images and considerably larger files. 150 DPI is ample for anything viewed on a screen. Choose 300 DPI when the result is going to paper, and expect roughly four times the file size.

Every page, in order

Each page becomes its own image, numbered in document order, so a 40-page report yields 40 files that stay in sequence.

Questions about converting PDF to JPG

Is the PDF uploaded to convert it to images?

No. Pages are rendered by this browser on your own device. The document is not transmitted and no server holds a copy of it.

What resolution should I choose?

150 DPI for anything read on a screen, 300 DPI if the images will be printed. Higher settings increase sharpness and file size together, with little visible benefit on screen.

Can I convert just one page instead of all of them?

Extract the page first with the Extract pages tool, then convert the single-page result. Both steps run locally.

Why is the download a zip file?

Because a browser cannot save many separate files at once without prompting for each. The pages are collected into one archive, which your operating system will unpack on a double click.
