Browser-Native Architecture

About FreePDFly IMG

Building high-performance, privacy-first web utilities that process images directly inside your browser without server uploads.

Our Mission

FreePDFly IMG was created to solve a fundamental security flaw in traditional online file conversion tools. Standard image processing platforms require users to upload confidential documents, personal photographs, ID cards, and proprietary design assets to remote cloud servers for rendering.

We believe file processing should happen where your data originates: on your local device. Leveraging modern Web APIs—such as HTML5 Canvas, OffscreenCanvas, WebAssembly, and client-side Web Workers—FreePDFly IMG executes complex image transformations locally inside your web browser.

Client-Side Architecture

Our technical framework is engineered from the ground up for speed, security, and portability:

  • HTML5 Canvas & OffscreenCanvas API: Enables hardware-accelerated image scaling, format re-encoding, color manipulation, and image filtering directly through your device's GPU.
  • WebAssembly Codecs: Runs compiled, high-performance C/C++ image decoders directly inside the browser sandbox, powering tools like HEIC to JPG Converter and TIFF to JPG Converter.
  • Client-Side Optical Character Recognition (OCR): Employs browser-based Tesseract.js engines to extract text from images in tools like JPG to Word DOCX OCR and JPG to Excel XLSX without transmitting document text across the network.
  • Web Workers: Offloads compute-heavy operations—such as multi-frame encoding in GIF Maker and batch operations in Image to ZIP—to background threads to ensure seamless UI responsiveness.
