Combine images into one PDF
Twenty photos of a document, one tidy PDF, in the order you choose.
- Nothing is uploaded
- Works offline
- Open source
- No limits, no watermark
Done
Open the network tab. It stays empty.
Add files and run the tool to see every request this tab makes.
Your files are processed on this device and never sent to a server. Reload the page to clear everything from memory.
The usual reason for this job: a landlord, school, insurer or visa office asks for "one PDF" and you have a dozen phone photos of pages, receipts or ID cards, some of them screenshots, some HEIC straight from an iPhone. Uploading all of that to a converter means handing over exactly the documents you would least like copied. Here the PDF is assembled in your browser tab, and the images never leave it.
Formats can be mixed freely: JPG and PNG go into the PDF without re-encoding, and HEIC, WebP, GIF, BMP and AVIF are decoded and stored as high-quality JPG. Every image becomes one page. This page starts on A4 with a 10 mm margin, because a combined document is usually going to be printed or read like paper; switch to US Letter, or to "Fit to each image" for a PDF of screenshots.
Order matters most when combining. Drop everything at once, then use the arrows to put the pages in sequence before you convert. Phone photos are turned upright using their orientation tag, so sideways shots come out the right way round.
How it works
- Drop every image that belongs in the PDF, or tap to pick them. Formats can be mixed.
- Put the pages in order with the arrows. Adjust page size, orientation or margin if needed.
- Convert. One PDF with all the images downloads from your browser.
In your browser, not on a server
JPG and PNG images are embedded directly into the PDF by pdf-lib without re-encoding. Other formats are decoded by your browser (HEIC via libheif, TIFF via UTIF.js, one page per TIFF page) and embedded as JPG or PNG. Page size, orientation and margins are applied while laying out each page in memory.
Compared with upload-based tools: Uploading a folder of receipts or ID scans to make one PDF is exactly the kind of thing that should not need a server. The PDF is assembled on your device in the time it takes to pick the files.
Verify it yourself. Load this page, turn off Wi-Fi or switch to airplane mode, and run the tool. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.
Questions
How many images can I put in one PDF?
There is no set limit. The practical ceiling is your device’s memory: a hundred phone photos is fine on a laptop, and most phones handle a few dozen comfortably.
How do I keep the PDF small enough to email?
Photos from a modern phone are 3 to 5 MB each, and they go into the PDF at that size. Shrink them first with [Compress image](/tools/compress-image), or run the finished PDF through [Compress PDF](/tools/compress-pdf).
I already have PDFs as well as images. Can I combine everything?
Convert the images here first, then join that PDF with the others on [Merge PDF](/tools/merge-pdf). Both steps run in your browser.
Is the file uploaded anywhere?
No. There is no server in this process. The page is a static file and the work is done by code running inside your browser tab. You can load the page, turn off Wi-Fi, and it still works.
