Need to turn a pile of photos or screenshots into one neat document you can email, print, or upload? Converting images to PDF is the cleanest way to do it — a single file, in the right order, that looks the same on every device. This guide shows you exactly how to convert JPG and PNG to PDF for free, combine several images into one PDF, and keep everything private.
If you just want to get it done, open our free Image to PDF converter — no signup, no watermark, nothing to install. Otherwise, here is the full rundown.
Why convert images to PDF?
A PDF wraps everything into one tidy, universal file. Converting images to PDF is useful when you want to:
- Combine many images into one file — easier to send than 12 separate attachments.
- Email or upload a single document for job applications, forms or submissions.
- Print photos or scans in order, one per page.
- Keep a consistent layout — a PDF looks identical on any phone, tablet or computer.
- Archive receipts, IDs or notes as a single, searchable-friendly document.
How to convert images to PDF (step by step)
Here is the quickest way, without installing anything or handing your photos to a server:
- Open the Image to PDF tool.
- Drag your images onto the box, or tap to pick them from your device or phone gallery. Add as many as you like.
- Reorder them if needed — each image becomes one page, top to bottom.
- Choose a page size (A4, Letter, or fit-to-image), orientation and margin.
- Click Convert to PDF and download your finished file.
The whole thing happens in your browser, so there is no upload wait — the PDF is built instantly on your own machine.
Combining JPG and PNG into one PDF
You are not limited to one image type. You can mix JPG photos, PNG screenshots and even WebP images in the same document. Add them all, arrange the order, and the tool stitches them into one PDF with each image on its own page. This is perfect for things like a set of receipts, a multi-page scan, or a portfolio of pictures.
Choosing the right page settings
A few options change how your PDF looks:
- A4 or US Letter — pick the standard page size for your region. The image is centered on the page with a margin.
- Fit to image — makes each PDF page match the image’s exact dimensions, with no white border. Great for photos and full-bleed images.
- Orientation — choose portrait, landscape, or let it match each image automatically.
- Margin — add breathing room around each image, or set it to none.
If you are unsure, “fit to image” gives the cleanest result for photos, while A4 is best for documents you plan to print.
Is it safe to convert images to PDF online?
Many converters upload your images to a server, process them, and send the PDF back — a real privacy concern for ID photos, receipts and personal pictures. The BSM Sites converter works entirely in your browser, so your images are never uploaded, stored, or seen by anyone. That makes it safe for sensitive documents.
Converting images to PDF on your phone
The tool is fully mobile-friendly. On Android or iPhone, open it in Chrome or Safari, select photos from your camera roll or gallery, arrange them, and save the finished PDF straight to your phone or share it from the browser. It is a quick way to turn snapshots of paperwork into a single document on the go.
Common questions and quick fixes
My images came out in the wrong order. Reorder them before converting — drag or use the up/down controls. The PDF follows the on-screen order, top to bottom.
The PDF file is too big. Lower the quality setting to compress the images, or remove any pages you do not need.
There is a white border around my photos. Switch the page size to “fit to image” and set the margin to none for edge-to-edge pages.
I need the reverse. To turn a PDF back into images, use the PDF to Image tool.

Frequently asked questions
How do I combine multiple images into one PDF?
Add all your images to an image-to-PDF tool, drag them into the order you want, then convert. Each image becomes a page, and they are saved together as a single PDF file you can download.
Can I convert images to PDF without uploading them?
Yes. Browser-based tools like the BSM Sites Image to PDF converter build the PDF on your own device, so your photos are never uploaded to a server and stay completely private.
Will converting images to PDF reduce their quality?
No, not by default. Your images are embedded at full resolution, so there is no quality loss. If you want a smaller PDF, you can lower the quality setting to compress the images.
