How to convert images into a PDF
- Drop your pictures on the dropzone or click to browse, select several at once, and each one becomes its own page. They stack in the order they're listed.
- Open the Page size menu: pick Fit to image for borderless pages that match each picture, or A4 / Letter to centre every image on a standard printable sheet.
- Drop any image you don't want from the list before building, so the final file holds exactly the pages you intend.
- Press Create PDF, then Download PDF to save the combined document to your device.
A PDF builder that keeps your images on your machine
Merging photos or scans into a single PDF is one of those small chores that comes up constantly: handing in scanned paperwork that only accepts one file, stapling a month of receipts together for an expense claim, returning a signed multi-page form, or bundling a set of photos into something easy to email. A PDF is the right container because it opens the same way on every phone, laptop and print shop, and it keeps your pages in a fixed order instead of arriving as a loose pile of attachments.
The problem with most converters is that they ask you to upload those pages to a stranger's server first, a genuinely bad idea when the pages are bank statements, an ID, or anything with a signature on it. This tool does the assembly locally instead. Each image is painted to a canvas, composited onto a white background so that transparent areas in a PNG or WebP don't turn black when printed, and written into the document by the jsPDF library, which is fetched once from a CDN and then reused. Your images are never transmitted anywhere. To reorder pages, remove the ones that are out of place and re-add them in the sequence you want before you build.
Choosing a page size
The Page size option changes how each picture sits on its page, and the right choice depends on whether the PDF is for screens or for paper. Fit to image makes every page the exact dimensions of its picture, edge to edge with no margin, ideal for photo collections, screenshots, comic or manga pages, and anything you'll only ever view on a device, because there's no wasted whitespace and portrait and landscape shots each keep their own shape. A4 (210 × 297 mm, the standard almost everywhere outside North America) and Letter (8.5 × 11 in, standard in the US and Canada) place each image centred on a fixed sheet, scaled to fit while keeping its proportions. Reach for those two whenever the file will be printed or fed into a system that expects consistent pages, such as a form upload or an office printer, so nothing is cropped and the paper size is predictable. If your source photos are heavy, run them through the compressor first to keep the finished PDF a reasonable size.
Frequently asked questions
Can I combine several images into one PDF?
Yes, that's the point. Add as many images as you like and they're merged into a single PDF, one picture per page, in the order they appear in the list. Remove any page you don't want before you build the file.
What's the difference between the page sizes?
Fit to image makes each page exactly match its picture with no borders, which is best for on-screen viewing. A4 and Letter centre each image on a standard printable sheet, pick A4 for most of the world and Letter for the US and Canada.
How do I control the page order?
Pages follow the order the images appear in the list. To move something, remove the images that are out of place and add them back in the sequence you want, then create the PDF.
Which image formats can I use?
JPG, PNG and WebP all work. Transparent regions in PNG or WebP files are flattened onto a white background first, so they don't render as black blocks when the page is printed.
Will the PDF be very large?
Its size tracks the images you add, high-resolution phone photos make big files. If the result is bigger than you want, shrink the pictures with the image compressor or a fixed target like compress to 200KB before combining them.
Are my images uploaded to make the PDF?
No. The document is assembled entirely in your browser and the pictures never leave your device. The jsPDF library is fetched once from a CDN, but your files are not part of that request.
