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.
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.
Compress a PDF to under 200 KB
200 KB is the comfortable end of the upload limits application forms impose. It is roomy enough that a short scanned document usually reaches it with the text still sharp, which is not true of the tighter limits. PaperJET picks the gentlest setting that fits rather than compressing as hard as it can, so you keep whatever quality the limit allows.
How to compress a PDF to under 200 KB
- Open the PDF. The 200 KB limit is already selected.
- Compress, and wait — scanned pages take longer than text pages, because the images are the work.
- Save the result. The before and after sizes are both shown, so you can see what it cost.
At 200 KB there is enough room for a few scanned pages at a resolution that still prints legibly. This is the limit at which compression stops being a fight.
A PDF exported from Word or a billing system is often well under 200 KB to begin with. PaperJET checks first and leaves such a file exactly as it is rather than re-encoding it for no gain.
Flattening pages to images is only tried near the floor, and only if it actually helps. At 200 KB it is rarely needed, so the result usually stays selectable and searchable.
Questions about the 200 KB limit
Is anything uploaded?
No. Everything runs locally in this browser tab. The document is read from your own storage and never leaves the device.
Will 200 KB look worse than the original?
On a scan, slightly — resolution comes down. On a document that was already text rather than images, usually not at all, because text is not re-encoded.
My file is 195 KB already. What happens?
Nothing. It is under the limit, so it is returned untouched. Compressing a file that already fits only loses quality for no reason.
Can I use this for a passport or visa application?
Yes. Those portals commonly set limits in this range. Check the exact figure the form states, and pick the matching limit — under is what counts, not close.
