Image to PDF

Turn images into PDF – without uploading

DocUpLift’s Image to PDF tool allows you to convert JPG, PNG, WebP, BMP, or GIF images into a single PDF document directly inside your browser. Each selected image becomes a separate PDF page, automatically scaled to maintain its original proportions and clarity. Unlike traditional online converters, your images are never uploaded to a server. Everything happens locally on your device, ensuring complete privacy and security.

This tool is ideal for combining scanned documents, receipts, certificates, notes, screenshots, or photos into one organized PDF file. Whether you are creating a digital portfolio, submitting assignments, preparing reports, or sharing multiple images in a professional format, converting images to PDF makes your files easier to manage and distribute.

The entire process is instant and requires no software installation. Simply select your images, arrange them as needed, and download the generated PDF. There are no watermarks, no registration requirements, and no hidden file size restrictions beyond your browser’s capability.

How to Convert Images to PDF Online

Step 1: Click the “Select images” button or drag and drop your files into the upload area. You can choose one or multiple images at once. Step 2: Preview the selected images and add more if needed. Step 3: Click “Download PDF” to instantly generate your document. The tool automatically places each image on its own page, preserving dimensions and quality. Within seconds, your PDF file will be ready to save.

Why Convert JPG or PNG to PDF?

PDF files are universally compatible and maintain consistent formatting across all devices. Converting images to PDF makes it easier to print documents, share multiple images as one file, and keep important records organized. PDFs are widely accepted for official submissions, professional communication, and archival storage, making them more practical than sending separate image files.

Is Image to PDF Safe?

Yes. DocUpLift is built with a privacy-first approach. All image processing takes place locally using your browser’s JavaScript engine and the jsPDF library. Your files never leave your device, and no data is stored, tracked, or analyzed. You can confidently convert sensitive images such as personal documents, contracts, or confidential materials without worrying about data leaks.

Best Use Cases for Image to PDF

This tool is useful for students submitting scanned homework, professionals sending invoices or contracts, freelancers creating portfolios, and businesses archiving receipts or reports. It is also perfect for mobile users who take photos of documents and need a quick way to combine them into a single printable PDF file.

Technical Explanation – How It Works

When you select images, your browser reads them using the FileReader API. The images are temporarily rendered onto a canvas element and inserted into a PDF document generated with the jsPDF library. Each image is scaled proportionally to fit the page dimensions while maintaining clarity. Because the entire process runs client-side, the conversion is fast, secure, and independent of any external server.

If you need to reduce file size before converting, try our Image Compressor. You can also crop images first using the Crop Image tool or resize them with our Resize Image tool to optimize your images before creating the final PDF.
