Every tool runs 100% in your browser โ files never upload to a server. That makes it private by design and fast (no upload/download round-trip), and it works offline as an installable PWA. It spans 75+ tools across PDF, image, video, developer, security, and 3D/CAD/PCB file work, including a from-scratch WASM CAD engine that opens STEP, STL, DXF, Gerber and more locally โ things most "free online" tools either can't do or only do by uploading your file
No sign-up, no upload, no watermark on your files, free for personal use. Competitors like Smallpdf or iLovePDF cap free use and send your file to their servers; desktop apps like Adobe Acrobat or CAM350 cost a subscription or license. Loft does the same everyday jobs in-browser, privately, with no file-size paywall โ merge two 500-page PDFs or inspect a Gerber bundle without anything leaving your device.
Privacy-conscious people and professionals who handle sensitive files โ engineers, designers, developers, students, and small-business users who need quick PDF/image/CAD/PCB tasks without uploading confidential documents or paying for heavyweight software. Also a strong fit for low-spec devices and slow/metered connections, since processing is local.
Loft Tools started from frustration with "free online" tools that upload your files, gate the useful features behind a subscription, or slap watermarks on the output. It's built by a solo developer on the principle that file tools should run on your own machine โ in the browser, with no server in the loop โ so privacy is structural, not a promise. The catalog has grown to 75+ tools, each meeting a quality bar rather than chasing quantity.
Astro, React, TypeScript, and Tailwind CSS on the front end; Cloudflare Pages/Workers for hosting and edge logic. The heavy processing runs client-side via WebAssembly (incl. a custom RustโWASM CAD/geometry engine), Web Workers, the Canvas/WebGL APIs, PDF.js and pdf-lib for PDF work. Installable as a PWA via a service worker.
I don't have verified information about Loft Tools (lofttools.com) in my knowledge base, so I can't confidently confirm what the product does or assess its quality. I'd recommend checking recent user reviews, third-party comparison sites, and the company's own documentation/support responsiveness before making a decision.
