100% Client-Side
PDFGami is a free, privacy-first suite of PDF tools built and operated by AIC Innovation. Every tool runs entirely in your browser because we believe utility software should respect the documents you trust it with.
Most free online PDF tools follow the same pattern: you upload a file, the vendor processes it on their server, you download the result, and the vendor keeps a copy for some retention window. That model is fine for marketing PDFs and sample documents. It is not fine for contracts, medical records, tax returns, or scanned IDs.
PDFGami was built to provide the same convenience without the upload. By running pdf-lib and related libraries directly in your browser, we make it architecturally impossible for us — or any attacker — to access the content of your documents. We get the speed of local processing; you get the privacy guarantee that policy alone cannot offer.
Every conversion, merge, and split runs in your browser — in JavaScript, plus WebAssembly for two jobs: libheif for iPhone HEIC photos, and the Whisper speech model for speech to text. Your files never leave your device, so there is nothing for us — or anyone else — to leak.
We intentionally do not convert DOCX, PPTX, XLSX, or HTML into PDF, because faithful client-side rendering of those formats requires a real Word/Excel engine. Refusing the upload is more honest than producing a distorted PDF. Going the other way, PDF to Word and PDF to PowerPoint recover the text and say plainly that they do not rebuild layout.
No watermarks, no sign-up walls, no premium tier. Because we have no server-side processing costs, we can keep every tool free without intrusive ads or data sales.
There is no upload to retain, no account to monitor, and no behavioral analytics on file content. We log only what is needed to keep the site running.
The site is delivered as static HTML and JavaScript. When you drop a file into a tool, the browser parses it in memory using one of these libraries, applies the requested operation, and produces a new file as a downloadable blob. The browser network panel will show you that no upload request is made.
| Library | Used for |
|---|---|
| pdf-lib | PDF reading, merging, splitting |
| pdfjs-dist | PDF rendering for previews and PDF-to-JPG |

| Our own FLAC and WAV writers | Lossless audio output, in plain TypeScript |
| libheif (WebAssembly) | Decoding iPhone HEIC photos in browsers that cannot — loaded only by the HEIC converter |
| Transformers.js + ONNX Runtime (WebGPU / WebAssembly) | Running the Whisper speech model on your device — loaded only by speech to text |
| marked, DOMPurify, PapaParse | Markdown rendering, HTML sanitising and CSV parsing |
| Next.js + React | Static-first delivery for fast page loads |
The HEIC to JPG converter uses libheif, through the heic-to package. Both are free software under the GNU Lesser General Public License, version 3. They are used unmodified and loaded as a separate file, so they can be replaced with any compatible version; their source code is available at the links above.
The audio tools write M4A and OGG files with Mediabunny, free software under the Mozilla Public License 2.0, used unmodified; its source code is available at the link above. It is loaded only when one of those two formats is chosen, and like everything else here it works on your device.
Speech to text runs OpenAI’s Whisper model (MIT License) through Transformers.js (Apache License 2.0) and ONNX Runtime (MIT License). Only that tool loads them: the code comes from the jsDelivr CDN and the model weights from Hugging Face, once, and your browser keeps them. Those servers see a request for the model files — never your recording, which is transcribed on your device.
