JPG, PNG, WebP — each becomes a page in the PDF
This turns images into a PDF without uploading them. Each image is embedded into a new document with pdf-lib inside your browser, in the order you arrange, at either A4 with margins or a page sized exactly to the image. Nothing is transmitted — which is the relevant detail when the images are photographed receipts, ID documents, signed forms or medical paperwork, the things people most often need as a PDF. JPG and PNG embed directly at their original resolution; WebP and other formats are redrawn through a canvas to PNG first, which also strips EXIF metadata including GPS coordinates from phone photos. One image becomes one page, so page count matches file count exactly. A4 suits anything destined for a printer or a formal submission, while fit-to-image suits screenshots and on-screen reading. Very large photo sets are limited by browser memory rather than any upload cap.

Should each image become an A4 page or fit the page to the image?
The page-size choice decides what the finished document is for. A4 centres each image on a standard page with margins, producing something that prints correctly on ordinary paper anywhere outside North America and looks conventional when attached to an email or filed with other documents. Choose it for anything going into a formal process — expense claims, applications, submissions — where a consistent page size matters and a printer will be involved. Fit-to-image creates a page with exactly the dimensions of the image, no padding and no letterboxing, which suits screenshots, photo collections, comic or manga pages, portfolio sheets and anything intended to be read on screen rather than printed. The practical difference shows up with mixed orientations: under A4, a landscape photo and a portrait one both sit centred on identically sized pages, while fit-to-image produces a document whose pages change shape as you scroll.
Formats, colour and what happens to your images
JPG and PNG are embedded directly, which means the image data is carried into the PDF unchanged — no re-compression, no quality loss, and a file size close to the sum of the originals. WebP and other formats the PDF specification does not support natively are converted to PNG first, which is lossless with respect to what your browser decoded but produces a larger file than the WebP was. Transparency in a PNG is preserved in the embedded image, though how it composites depends on the viewer and generally renders against white. Two practical notes. First, photographs from phones are frequently very large — a 12-megapixel image is several megabytes — so a PDF of thirty holiday photos can run past 100 MB; compress the images first if the PDF needs to be emailed. Second, embedded images retain their EXIF metadata, including GPS coordinates where present, so strip location data beforehand if the document is going to someone you would not want to share it with.
Getting scanned documents to look right
The most common use is turning phone photographs of paper into a document that looks like a scan rather than a snapshot, and a few habits make a large difference. Shoot straight down in even light — angled shots produce keystoned pages that no page-size setting can correct, and a hard shadow across the page is far more visible in a PDF than on screen. Crop each photo to the paper's edges before creating the PDF, so the document does not carry a border of desk or carpet; the crop tool handles this and the result reads as a proper document. Use A4 for anything that may be printed. If the images are colour photographs of black-and-white paper, they will be much larger than they need to be, so running them through the image compressor first typically cuts the finished PDF dramatically with no meaningful loss of legibility. Finally, put the pages in order before generating, since reordering afterwards means starting again.
Choosing a page size
| Your images are | Use | Result |
|---|---|---|
| Documents to be printed | A4 | Standard pages with margins |
| Screenshots for screen reading | Fit to image | No padding, exact dimensions |
| Mixed portrait and landscape | A4 | Consistent page size throughout |
| Photos for a portfolio | Fit to image | Edge-to-edge pages |
| Receipts for an expense claim | A4 | Prints and files conventionally |

Frequently asked questions
Are my images uploaded to a server?
No. The PDF is assembled in your browser with pdf-lib. Nothing is uploaded, stored or transmitted at any point.
What image formats can I convert?
JPG and PNG are embedded directly with no re-compression. WebP and other formats your browser can decode are converted to PNG first, which is lossless but produces a larger file.
What is the difference between A4 and fit-to-image?
A4 centres each image on a standard printable page with margins. Fit-to-image makes each page exactly the size of its image, with no padding — better for screen reading.
Will the PDF have any watermarks?
Never. The output contains only your images — no branding, no added pages, no sign-up required.
Why is my PDF so large?
Phone photographs are several megabytes each and are embedded without re-compression. Run them through the image compressor first if the PDF needs to be emailed.
Can I change the page order?
Yes, drag the images into the order you want before generating. Reordering after the PDF is created means starting over.
Is my location data included?
Embedded images keep their EXIF metadata, which can include GPS coordinates. Strip location data before converting if the document is going to be shared.
How do I make photos of paper look like a scan?
Shoot straight down in even light, crop to the paper's edges first, and use A4. Angled shots and visible desk borders are what make a photo look like a photo.
Does transparency survive?
PNG transparency is preserved in the embedded image, though most viewers composite it against white when displaying the page.
