Image to PDF lets you combine photos and graphics into a single, well-formatted PDF without any uploads. The conversion runs entirely in your browser, so your images stay private and are never sent to a server. Pick your page size such as A4 or Letter, choose portrait or landscape orientation, and control margins and how each image fits the page. It is free, requires no account, and produces a clean, ready-to-share document in moments.
How to convert images to PDF
- 1 Add your JPG, PNG, or WebP images.
- 2 Choose page size, orientation, and margins.
- 3 Reorder images to match your desired layout.
- 4 Export and download your finished PDF.
How images become PDF pages
Each image is decoded in your browser and then embedded into a new PDF document built with pdf-lib. One image becomes one page. The page itself is a real PDF page at A4 or Letter size in the orientation you choose, and the image is placed inside it according to the margin and fit you set — "contain" scales the image until it fits entirely within the content box, while "cover" fills the box completely and crops the overflow.
There is a constraint worth explaining, because it shapes the tool. The PDF format only supports JPEG and PNG image streams directly, so anything you add in another format — WebP, GIF, and often the HEIC files a modern iPhone produces — is first re-encoded to one of those two through a canvas. That conversion is lossless for PNG-suitable images and visually transparent for photographs, but it is the reason a WebP import produces a slightly larger page than you might expect.
Everything is assembled in memory and delivered as a download. The images never travel anywhere, which matters more here than for most conversions: photographing a passport, a receipt or a signed form and turning it into a PDF is one of the most common reasons anyone needs this tool.
Common jobs
Photos of documents
Phone photographs of a signed form or an ID are almost never accepted as JPEGs. One pass through this tool produces the single PDF that portals and HR systems ask for.
Receipts for an expense claim
Twenty receipt photos become a twenty-page PDF in the order you arrange them. Small margins and "contain" keep every edge of the receipt visible, which is what an approver needs to see.
Portfolios and contact sheets
A sequence of images at Letter or A4 with generous margins produces a presentable portfolio that opens identically on every device — unlike a folder of images, whose order depends on the viewer.
Screenshots for a report
Landscape orientation with "contain" fits wide screenshots without cropping, which is usually what you want when the content at the edges is the point.
Why convert images to PDF
A PDF is the ideal format for sharing photos, receipts, or scanned notes as one tidy file that looks the same everywhere. With flexible page size, orientation, margins, and image-fit options, you stay in full control of the layout. Everything is processed on your device, keeping personal images completely private and free of charge.
Things to know before you convert
A few behaviours are worth understanding up front:
- The output is a picture of your document, not a searchable one. There is no OCR: text inside the image stays an image, so the resulting PDF cannot be searched or copied from.
- "Cover" crops. It fills the page edge to edge, which looks better for photographs but will cut off the outer part of a document scan — use "contain" whenever every edge matters.
- File size follows the source images. Modern phone photos are several megabytes each; twenty of them produce a large PDF. Resizing them first with the Image Resizer will often cut the result by an order of magnitude with no visible loss.
- HEIC support depends on your browser. Safari on Apple devices decodes it natively; most other browsers do not, in which case convert to JPEG first.
- Every image gets its own page at the size you chose. Placing several images on one page, or matching page size to image dimensions, is not part of this tool.
Troubleshooting
- My photo is sideways in the PDF
- Phone cameras record orientation as EXIF metadata rather than rotating the pixels. Browsers honour that flag inconsistently when decoding. Rotating the image in your photo app — which rewrites the actual pixels — and re-adding it fixes it reliably.
- The PDF is enormous
- Because the images are. A 12-megapixel photo carries far more detail than a printed page can show. Run them through the Image Resizer at around 1,600 pixels on the long edge first; the PDF will typically shrink by 80–90% and look identical on screen and in print.
- A HEIC file will not load
- Your browser cannot decode HEIC. Convert the photos to JPEG first — on an iPhone, sharing them via any non-Apple app usually converts them automatically, or you can change Camera settings to capture in "Most Compatible" format.
Frequently asked questions
Which image formats can I convert?
You can convert JPG, PNG, and WebP images into a single PDF document.
Can I change the page size and orientation?
Yes. Choose A4 or Letter, portrait or landscape, and adjust margins and image fit before exporting.
Can I make the text in my scanned document searchable?
Not with this tool. Turning an image of text into selectable text requires OCR, which is a fundamentally different process from wrapping the image in a PDF. The PDF produced here shows your document faithfully but the words inside it remain pixels.
Which page size should I choose?
A4 if you are anywhere outside North America, Letter if you are in the US or Canada. The difference is small — A4 is slightly narrower and taller — but choosing the wrong one causes scaling and margin problems when the document is eventually printed.
Can I reorder the images before converting?
Yes. Drag the thumbnails into the sequence you want; pages are generated in exactly the order shown. This matters more than it seems, because the order a file dialog returns files in is not guaranteed to match how you selected them.
Are my photos uploaded?
No. Decoding, layout and PDF assembly all happen in your browser tab, and the finished file is handed to you through a local blob URL. Given that this tool is most often used on identity documents and receipts, that property is the point rather than a footnote.
