Common use cases

Kenji, a contractor, combines 45 phone photos of a job site into a single PDF report for the property owner. This ensures that all images are securely stored in one place, without the risk of data leakage, making it easy to share and keep a record of the job site’s progress.

Aisha, a nursing student, converts 80 lecture-slide screenshots into a chronological PDF study guide. The browser-based privacy ensures her study materials remain confidential, which is crucial for maintaining the integrity of her education materials.

Felix, a parent, packages 30 scanned children’s drawings into a single keepsake PDF to share with grandparents. Since the conversion happens entirely in the browser, there’s no risk of the drawings being compromised or uploaded to a server, ensuring family privacy.

Beatriz, a small-business owner, combines 25 receipt photos from a business trip into a single PDF for an expense report. With no server upload, her financial information remains private, avoiding the potential risks associated with cloud-based services.

How it works (privacy & technical)

Our JPG/PNG to PDF Converter uses pdf-lib 1.17.1 and PDF.js 3.11.174 to process files entirely in your browser. PDFs are loaded as Uint8Array byte streams in browser memory, and operations such as PDFDocument.copyPages and getPage are executed in the JavaScript engine. This means the browser network layer is never involved for file content, ensuring your files remain private and secure. Contrast this with server-based tools that require upload and potentially expose your files to server logs and potential security risks. With AccuPDF, files never leave your device, so they don’t appear in any server log.
