🖼️ JPG to PDF Converter ☆

Overview

Free JPG to PDF is a free online tool that converts JPG, PNG, and other image files into PDF documents. Upload one or multiple images, arrange them in any order, and the tool creates a single PDF with each image on its own page. You can choose the page orientation (portrait or landscape), set margins, fit images to page size, or keep original image dimensions. The tool automatically adjusts page size to match each image's aspect ratio when needed. All processing happens locally in your browser. Your images are never uploaded to any server. Combine as many images as you like; there is no account requirement and nothing is watermarked. It is ideal for combining scanned pages into a single PDF, creating photo albums in PDF format, converting receipts or invoices captured with your phone camera into organized documents, assembling design mockups into a shareable PDF, or preparing image-based content for printing or digital submission. The output PDF maintains the full resolution of the original images. Available on desktop and mobile browsers alike, including Windows, macOS, Linux, iOS and Android.

How images become a PDF

Each image is decoded, drawn onto a canvas at its original resolution and embedded into a new PDF page sized to your settings, A4, Letter, or matched to the image itself. The result is a real PDF with one page per image, not a slideshow or an archive: text stays selectable where present, and the file opens in any reader. Order is set by drag-and-drop before conversion, and margins, orientation and fit mode are applied uniformly, so a set of phone photos becomes a tidy, printable document in seconds.

Privacy: photos are never uploaded

Receipts, ID scans and personal photos should not pass through a stranger server to become a PDF. This tool reads images locally, assembles the document in browser memory and returns it as a download. Nothing is transmitted or stored, and closing the tab releases everything.

Tips for clean, printable PDFs

• Shoot documents straight-on with even lighting before converting.
• Use fit-to-page with small margins for receipts and forms.
• Keep original dimensions when resolution matters, such as design proofs.
• Put cover images first; readers see the first page as the thumbnail.
• Compress the finished PDF if it is too large for email.

Image resolution, page fit and ordering

Combining images into a PDF is straightforward, but the output quality is decided before conversion. Resolution is the first factor: a phone photo is usually far larger than a printed page needs, while a small web image may look soft when stretched to A4. The practical target for print is around 300 pixels per inch at the final size, so a full-page A4 image needs roughly 2480 by 3508 pixels; anything larger is wasted, and anything much smaller will show. Fit mode matters just as much: stretching every image to fill the page distorts aspect ratios, while fitting the longest side and centring the image preserves proportions and leaves white margins. Orientation should be respected, including the EXIF rotation flag that phone cameras set, otherwise portraits appear sideways. Order is easy to get wrong when filenames are not sequential, a natural sort that understands numbers puts page 2 before page 10, while a plain alphabetical sort does not. Decide between one image per page and a contact-sheet layout, and remember that each page can carry its own size, which is useful when mixing scans and screenshots. Everything is processed locally in your browser.
