Frequently asked questions

Are my images uploaded to a server?
No. The PDF is built locally in your browser. Your images never leave your device.
Can I combine multiple images into one PDF?
Yes — add as many as you like and arrange the order before converting. Each image becomes one page.
What image formats are supported?
JPG, PNG and WebP. Transparency in PNG and WebP is rendered on a white background.
Will the PDF pages be a standard size like A4?
Each page is sized to match its image exactly, so nothing is cropped, stretched or padded. Most PDF viewers and printers scale pages to fit the paper automatically when you print.
How do I keep the PDF small?
The PDF can only be as small as the images inside it. Compressing or resizing your photos first — for example to 1600 pixels wide — typically cuts the final PDF size dramatically with no visible difference on screen.

About this tool

PDF is the format institutions expect: it prints predictably, keeps its layout on every device, and bundles any number of pages into one attachment. Converting images to PDF is the standard way to submit scanned documents, receipts, signed forms, homework and portfolios — anywhere a loose pile of photos would be awkward to send or review. Unlike an image gallery, a PDF also fixes the viewing order, so a multi-page scan reads correctly on every device.

This tool gives each image its own page, sized to the image’s natural dimensions so nothing is cropped, stretched or padded with margins. Add as many images as you like, arrange them with the arrows, and the finished PDF follows that order exactly. JPG, PNG and WebP all work; transparent regions are rendered on a white background, matching how the page would print.

A practical tip: the PDF inherits the size of the images inside it, so ten photos straight off a phone can produce a 40 MB document. Running the images through the compress or resize tool first — around 1600 pixels wide is plenty for documents — keeps the PDF light enough to email without any visible loss. JPG input generally produces the smallest PDFs; PNG is worth keeping for pages where crisp text matters most.

The document is assembled entirely in your browser. Nothing is uploaded, which matters for the ID scans, contracts and personal paperwork this tool is most often used for — your images and the finished PDF exist only on your device.
