What Is an Image to PDF Converter?

An Image to PDF Converter turns photos, scans, screenshots, and graphics into a PDF document. PDF is widely used because it presents fixed-layout pages that are easy to share, open, archive, and print across many systems.

This tool is useful for document scans, assignments, business reports, contracts, invoices, receipts, portfolios, presentations, image archiving, and printable photo documents. It creates the PDF locally in the browser from the images you choose.

Method

How the Image to PDF Converter Works

Upload imagesChoose one or more image files using the file picker.
Page orderSelected images appear in the order they will be written to the PDF.
Reorder and removeUse Up, Down, Remove, and Clear before creating the file.
Quality sliderThe JPEG quality setting controls the canvas export quality used for PDF pages.
Automatic page sizingEach PDF page uses the pixel width and height of the rendered image canvas.
Download PDFThe converter creates and downloads a PDF from the selected pages.

Formats

Supported Image Formats

The file picker accepts image files and the interface lists JPG, PNG, WebP, and GIF. In practice, conversion depends on browser image decoding throughcreateImageBitmapand canvas rendering. Unsupported or damaged image files may fail during conversion.

The generated PDF embeds each rendered page as JPEG image data. It does not keep PNG transparency, animated GIF frames, layers, vector objects, or OCR text.
