There's no backend processing your files: no upload, no storage, no server round-trip. Everything happens locally via JS, so your documents never leave your device. That's the whole pitch — it's the same reason I built it, since most PDF tools online quietly funnel your files through a server you have no visibility into. <p>All 20+ tools are free with no sign-up.</p> <p>Today I'm adding a small premium option: batch processing, for ₹9.99 per batch (~$0.10 USD), one-time — no subscription. Run a tool across multiple files in one go instead of one at a time. Everything else on the site stays free and unlimited.</p> <p>Tech-wise it's a single HTML file backed by client-side JS libraries — no framework, no build step. It's a PWA, so it installs and works offline once loaded.</p> <p>Would love feedback — especially on the privacy angle, the batch pricing, or tools you think are missing.</p> <div class="crayons-card c-embed text-styles text-styles--secondary"> <div class="c-embed__content"> <div class="c-embed__cover"> <a href="https://onepagepdfconverter.com/" class="c-link align-middle" rel="noopener noreferrer"> <img alt="" src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fonepagepdfconverter.com%2Fog-image.png" height="420" class="m-0" width="800"> </a> </div> <div class="c-embed__body"> <h2 class="fs-xl lh-tight"> <a href="https://onepagepdfconverter.com/" rel="noopener noreferrer" class="c-link"> Free Online PDF Converter – Word, HTML, Image &amp; More Tools </a> </h2> <p class="truncate-at-3"> Free online PDF converter with complete privacy protection.
