Images → PDF

Combine several images into a PDF document.

Select or drag & drop images (multiple = multiple pages)

All processing happens entirely in your browser.

You photographed six pages of a signed contract with your phone, and the other side wants one PDF, not six attachments. This tool stacks the images into a single document in the order you picked them, with a page size you choose. Everything happens in the browser, so a scan of something private never gets uploaded anywhere.

How it works

How pages are built

Each image becomes one page, in the order the files were selected. The document is assembled by jsPDF inside your browser, so the images never leave your machine.

Page size options

Option	What it does
A4	210 x 297 mm page; the image is scaled to fit inside a 10 mm margin and centred
Letter	216 x 279 mm (8.5 x 11 in), same fit-and-centre behaviour
Fit to image size	The page is created at the image's own pixel dimensions, so the picture fills it edge to edge with no margin

With A4 or Letter the image is scaled down proportionally and never stretched or cropped, so a wide photo on a portrait page leaves blank bands above and below. Pick Landscape for wide images, or Fit to image size when you want no whitespace at all. The orientation setting is ignored in Fit mode, where each page follows its own image.

Formats and file size

PNG files are embedded as PNG so flat graphics and screenshots keep their sharp edges; JPEG, WebP and other types are embedded as JPEG. Images go in at full resolution, so a dozen photos from a modern phone camera make a heavy PDF - resize them first if the file has to be emailed.

Terms explained

A4: The ISO standard page size, 210 x 297 mm - the document default across most of the world outside North America.
Letter: The North American standard page size, 216 x 279 mm (8.5 x 11 inches).
Fit to image size: Builds each page at the image's own pixel dimensions instead of a fixed paper size, leaving no margin or whitespace.
Orientation: Whether a page is taller than wide (portrait) or wider than tall (landscape). It has no effect in Fit to image size mode.
Margin: The blank border kept around the image on A4 and Letter pages - 10 mm on every side.

Frequently asked questions

Are my images uploaded to a server?

No. The PDF is assembled entirely in your browser with JavaScript, so the images never leave your device. Once the page has loaded you can even go offline and the tool still works.

How do I control the page order?

Pages follow the order in which the files were selected, and most file pickers sort by filename. Numbering your files - 01.jpg, 02.jpg, 03.jpg - is the simplest way to lock in the sequence.

Why is there white space around my image?

On A4 and Letter the image is scaled to fit the page without cropping, so any mismatch in aspect ratio shows up as blank bands. Switch the orientation, or choose Fit to image size for an edge-to-edge page.

Which image formats can I use?

Anything your browser can display, including JPEG, PNG, WebP and GIF. PNG is embedded as PNG to preserve sharp edges; other formats are embedded as JPEG.

Why is the PDF so large?

Photos are embedded at their original resolution, so ten 12-megapixel images produce a very large file. Resize or compress the images before converting if size matters.
