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.

Read the text from a scanned Telugu document

Telugu is well served by scanners and badly served by the tools that come after them. A scanned Telugu page holds no text to search or copy, and most online readers offer English, shrug at anything else, and hand back nonsense. This uses the Telugu model, and runs it in this browser tab rather than on somebody's server.

How to read the text from a scanned Telugu document

  1. Open the scanned PDF. Telugu is already selected as the language.
  2. Run the recognition. The Telugu model is about 1.2 MB and is fetched once, then kept.
  3. Save. The page looks exactly as it was scanned, with the recognised text added underneath as an invisible layer.
Telugu is not Devanagari

Hindi and Marathi share a script; Telugu does not share it with either. Its letters are rounded, built from a consonant with vowel marks attached around it, and a model trained on Devanagari cannot read them at all — not badly, but not at all. Choosing the language here is what makes the difference between text and nothing.

Compound letters need a clean scan

Telugu stacks consonants, hanging the second beneath the first. Those lower marks are small and are the first thing lost to a faint photocopy or a photograph taken at an angle. A flatbed scan at 300 DPI is worth the trouble.

The scan itself is untouched

Recognised text goes behind the original page image rather than replacing it. Where recognition is imperfect the document still looks exactly as it did, and nothing has been thrown away.

Questions about Telugu OCR

Is my Telugu document uploaded?

No. The recognition engine and the Telugu model both run locally in this browser tab. Nothing is transmitted and no server keeps a copy.

Why did another tool return nothing for my Telugu scan?

Almost certainly because it was reading with an English or Hindi model. Telugu has its own script and needs its own model — an English one finds no letters it recognises.

How accurate is it?

Good on clean printed Telugu at a reasonable resolution. Compound consonants, where one letter sits beneath another, are where errors concentrate, and a faint or skewed scan makes them much worse.

Can it read a document with Telugu and English mixed?

Yes — pick the combined English and Telugu option from the language list on the OCR tool, which loads both models at once.

Does it work on handwritten Telugu?

No, not reliably. The model is trained on printed text, and handwritten Telugu is beyond what it can do.
