Sending eight photos as eight attachments asks the recipient to open eight things and work out the order. Sending one PDF asks them to open one, and the order is already decided. That is the entire case for combining images into a document, and it is why receipts, scanned forms, portfolio pages and identity documents almost always end up as PDFs rather than as folders of images.
The choice that shapes the result is the page size, and there are two genuinely different answers. A4 or Letter puts every image on a standard printable page, scaled to fit and centred — right when the document will be printed, filed, or submitted somewhere that expects paper proportions. Fit mode instead makes each page exactly the dimensions of the image on it, so there is no white space at all and no fixed orientation; the document simply becomes the images. That suits screenshots, artwork and anything meant to be read on screen.
Order and margins do the rest. Pages follow the thumbnail sequence, not filenames, so dragging them into place before generating is what stops a scanned form arriving out of sequence. Margins add white space around every image on standard page sizes — useful for documents that will be printed and punched, unnecessary for anything read on a screen.
How to combine multiple images into one PDF
- 1
Add every image at once
Drop the whole set in. Each becomes one page, and everything is processed in your browser rather than uploaded — which matters when the set is scans of personal documents.
- 2
Drag the thumbnails into order
Page order follows the thumbnails exactly. Filenames are ignored, so a set of photos named by timestamp still needs arranging if the shooting order was not the reading order.
- 3
Choose the page size
A4 or Letter for anything printable, in portrait or landscape. Fit if you want each page to match its image exactly — orientation is then decided per page automatically, so those buttons switch off.
- 4
Set margins and download
None, small, or large. Then generate: the PDF is assembled in your browser and saved directly, with no email address and no watermark.
Pro tip: Rotate and crop before you add images, not after. A PDF page is generated from the image exactly as supplied, so a scan that is upside down stays upside down and a photo with half a desk in it keeps the desk. Fixing that afterwards means regenerating the whole document. Running the set through Crop Image first — straightening scans and trimming edges — takes a few minutes and produces a document that looks assembled rather than accumulated.
Troubleshooting: If pages are in the wrong order, the thumbnails were not arranged before generating; the sequence follows them rather than the filenames. If images sit in a lot of white space, the page size is A4 or Letter and the image proportions do not match paper — switch to Fit if the document is for screen. If the file is very large, that is the image resolution rather than the PDF; compressing the images before adding them is more effective than compressing the document afterwards. If orientation buttons do nothing, Fit mode is selected and each page takes its orientation from its own image.
For specific formats, Convert JPG to PDF Online and PNG to PDF Converter cover what happens to each on the way in. If you want the images joined into one continuous picture rather than separate pages, Merge JPG Files Into One does that instead. Large sets are worth shrinking first — Compress Image to 1MB keeps a document emailable. The full Image to PDF tool has every option in one place.
Frequently asked questions
How do I combine multiple images into one PDF?
Add all the images to the tool above, drag the thumbnails into the order you want, choose a page size, and download. Each image becomes one page of a single document, assembled in your browser without anything being uploaded.
What page size should I choose?
A4 or Letter when the document might be printed or submitted somewhere that expects paper proportions — each image is scaled to fit and centred. Fit when it will be read on screen: each page becomes exactly the size of its image, with no white space and no fixed orientation.
Can I change the order of pages in the PDF?
Yes, by dragging the thumbnails before you generate. Page order follows the thumbnail sequence rather than filenames, which matters for scanned documents where the capture order and the reading order are often different.
Why is my PDF file so large?
Because the images are. A PDF made from a dozen full-resolution phone photos inherits their pixel count. Compressing the images before adding them is far more effective than trying to reduce the document afterwards, since the images are what the file is mostly made of.
Is my document uploaded to a server?
No. The PDF is generated locally in your browser using JavaScript, so scans, contracts and identity documents are never uploaded, stored, or logged. The tool also works with your connection switched off once the page has loaded.
