Why we built this
Most online PDF tools work like this: you upload a file to a server you don't control, a stranger's machine processes it, and you trust that whatever copies got made along the way actually get deleted. For a contract, a payslip, a medical form, or a scanned passport, that trust is a lot to ask.
Modern browsers can do all of this work locally. The libraries are mature, the performance is good, and the JavaScript engine on your phone is more than capable of merging, splitting, compressing, and converting a PDF without sending a byte to anyone. So we built iSavePDF that way. Files are picked up by JavaScript running in your browser tab, processed on your device, and saved straight back to your downloads folder. No upload step exists, because there is no server to upload to.
What iSavePDF is — and isn't
It is twelve PDF tools that solve the most common day-to-day problems: merging files, compressing big ones, converting between PDF and JPG/PNG, rotating pages, splitting documents, deleting unwanted pages, adding page numbers, watermarking, and pulling out plain text. Each tool gets its own page, its own URL, and its own small bundle of code that only loads when you actually use it.
It isn't a knockoff of Adobe Acrobat. We don't do OCR, e-signatures, form-filling, redaction, or PDF-to-Word in this version — those are meaningfully harder problems and the honest answer is that pdf-lib in the browser isn't the right tool for them. We may add more in future versions, but only if we can do them well and keep them free of server-side compromise.
About Two Quarters Ventures
Two Quarters Ventures is a small portfolio of independent web products. The thread connecting them is the same thing you'll see on iSavePDF: we like building useful, fast, free things, and we don't like asking users to trade their data for the privilege of using them. iSavePDF is the first of these to be public; more are on the way.
The site is supported by display advertising — three banner slots, no interstitials, no popups, no dark patterns. That keeps it free for you, keeps the lights on for us, and keeps us out of the business of collecting personal information we don't need. If you want the longer version of the privacy story, the security page has it.
