About Quill

Who makes it

Quill is built and operated by Ashish Jadhav, an independent software developer based in Maharashtra, India. It is not a company, a venture-funded startup, or a front for a larger business. It is one developer's project, and you can reach that developer directly at ashishjadhav9900@gmail.com.

Why it exists

Most free online PDF tools follow the same pattern. You upload your file to a server you know nothing about, wait in a queue, hit a daily limit after two or three documents, and get back a file with a watermark stamped across it unless you subscribe. For a contract, a payslip, or a medical form, handing the document to a stranger's server is a genuinely bad trade for the convenience.

Quill was built to remove the upload. Browsers can now parse, render, modify and write PDFs quickly enough that a server is unnecessary for almost everything people actually need — merging, splitting, compressing, rotating, signing, annotating, redacting, converting. If the work can happen on your own machine, the privacy question answers itself.

How it works

Every tool on this site is JavaScript and WebAssembly running in your tab. When you drop a PDF onto a page, the file is read into memory in your browser, modified there, and written back out as a download. There is no upload step, because there is nothing on our side to upload to: we run no document endpoint and no conversion queue.

The practical trade-off is that the work is bounded by your device rather than by a server, so an unusually large file is limited by your available memory. In exchange, there is no queue, no daily cap, and no file sitting on someone else's disk.

How it is paid for

Quill is free, and there is no paid tier — no Pro plan, no upgrade, no feature held back behind a subscription. Everything on the site works for everyone, without an account and without a watermark.

Hosting and domain costs are covered by advertising. Ads are clearly labelled, are kept out of the editing surface, and are served by Google AdSense. That is the entire business model. We do not sell data, and the site's analytics are not used to build advertising audiences.

What it is not

Quill is not a document management system, a cloud drive, or a replacement for a certificate-based e-signature service. It does not store your files, keep a history, or sync between devices, because it never receives your files in the first place. If you need a cryptographic digital signature that binds an identity to a document and detects later tampering, you need a certificate authority, not Quill.

Feedback

Bug reports and feature requests are genuinely welcome, particularly with a description of the document that caused the problem. Write to ashishjadhav9900@gmail.com.
