How to Convert Images to PDF: One File, the Right Size
Job applications, visa forms, insurance claims, school portals: many of them want one PDF, not ten separate photos. A PDF keeps the pages in order, opens the same way on every device and prints at the right size.
This guide shows how to turn photos, scans and screenshots into a PDF with the free Image to PDF tool, which settings to choose for different jobs, and how to make the file small enough to upload.
How to convert images to PDF, step by step
- Open Image to PDF and click Choose images, or drag them onto the page. You can add up to 50 at a time, in JPG, PNG, HEIC, WebP, AVIF, GIF or BMP, mixed as you like.
- Put them in order with the ↑ and ↓ buttons. The first image becomes page 1.
- Under Output, choose One PDF with all images, or One PDF per image if you need separate files.
- Pick the Page size (A4, US Letter or Fit to image), the Orientation and the Margin. The settings are explained below.
- Click Create PDF, then Download. With one PDF per image, Download all as ZIP saves them in one go.
Changing a setting and creating the PDF again doesn’t use up more of your daily allowance: each image counts once.
Which settings to choose
Documents and scans you will print or submit
Choose A4 (or US Letter in the US and Canada), orientation Automatic and a Normal margin. Every page then has the same paper size, which is what most forms and printers expect. Automatic turns each page to match its picture, so a wide photo lies on a landscape page.
Photo albums, portfolios and screenshots
Choose Fit to image and no margin. Each page is then exactly the size of its picture, with no white borders, which looks best on screen.
Receipts and notes for your own records
A4 or Letter with a Small margin keeps the receipt readable and leaves a little room around the edges for printing.
How to make the PDF smaller
Phone photos are large: ten of them can easily make a 30 MB PDF, while many upload forms stop at 2, 5 or 10 MB. Two settings shrink the file the most:
- Image size: Medium (1600 px) is still sharp on screen and on paper, and makes each page several times smaller than Original. Use Large (2400 px) for detailed documents with small print.
- Quality: 70–85% looks the same as the original to most eyes and saves a lot of space. Go lower only for text documents.
Create the PDF, check its size next to the download button, and if it’s still too big, lower the image size or quality and create it again. If you only need smaller pictures and not a PDF, the Image Compressor does that, and this guide explains how.
Good to know
- iPhone photos work directly. HEIC images are converted for you, so there’s no need to change them to JPG first. (If you do need JPGs, see how to convert HEIC to JPG.)
- Transparent areas become white, as on paper.
- Animated GIFs use their first frame, because a PDF page is a still picture.
- Photo details such as the location are removed, so the PDF doesn’t reveal where the pictures were taken.
- Scans look best when straight and well lit. Photograph documents from directly above, in daylight, and crop away the table before you add them.
Converting one kind of image?
Each format also has its own page with the same tool:
Are my images uploaded?
No. The PDF is made inside your browser, so your photos and documents never leave your device. That matters for IDs, payslips and other private papers. Our server only records how many images were converted, for the daily limit.
Frequently asked questions
Can I combine images into one PDF?
Yes. Choose One PDF with all images: each image becomes one page, in the order you set.
Will my images lose quality?
With image size Original and quality at 90% or more, the difference is hard to see. Lower settings make a smaller file with a little less detail.
How many images can I add?
Up to 50 at a time. For more, create several PDFs.
Can I edit the PDF afterwards?
Not with this tool. To change the order or settings, simply create the PDF again; it’s free for images you have already added.
