How the Image to PDF Converter works

The image to PDF converter puts one or more images into a single PDF document directly in your browser. Add your images, put the pages in order with the up and down buttons, choose the page size (A4, A3, Letter or fit to the image), the orientation, how each picture fits and the margin, then download the finished PDF — all without uploading files to any server. Ideal for scanning documents with a phone camera, compiling multi-image reports, and creating portfolios. Each image becomes one page, and the file is saved as images.pdf.

Supported image formats and quality

The converter accepts any image your browser can read: JPEG (best for photographs), PNG (lossless, best for screenshots and documents with text), WebP and GIF (a GIF becomes a still picture). A JPEG is placed into the PDF exactly as it is, with no recompression, so photo quality is kept and the PDF is about as large as the photos added together: in our test a 215 KB JPEG produced a PDF about 1 KB larger. The exception is a JPEG that a phone stored sideways with a rotation tag: it is redrawn upright and saved at 95% quality, so it does not come out rotated. PNG, WebP and GIF images are redrawn and stored as PNG image data, so a PNG keeps any transparency, shown on the white page.

Page size and image fitting options

A4 is 210×297 mm, A3 is 297×420 mm and US Letter is 8.5×11 inches. Fit to image makes each page the picture's own pixel size, so a 4000×3000 px photo becomes a page about 55.6×41.7 inches: fine on screen, enormous on paper. The Image fit setting has three choices. Contain keeps the whole picture visible at its own proportions, with blank space where the shapes differ. Fill page stretches the picture to fill the area inside the margins, so a picture of a different shape looks distorted rather than cropped. Actual size places the picture at its pixel size in points, which may spill off a small page. The margin slider runs from 0 to 80 points; the default 20 points is about 7 mm.

Portrait vs landscape orientation

Portrait orientation (taller than wide) suits documents, scanned forms, and phone photos taken vertically. Landscape suits wide photos, diagrams, spreadsheets, and presentations. The orientation you choose applies to every page of a fixed size such as A4, so a mixed set of tall and wide pictures looks best with Fit to image, or in separate PDFs joined afterwards with the PDF merger. A 4000×3000 photo on A4 landscape at the default settings prints at roughly 389 pixels per inch, and on A4 portrait at roughly 519, more than enough for print.

What this tool does not do

It does not crop, resize or compress the pictures, and it cannot read formats your browser cannot open: an iPhone HEIC photo may be refused in some browsers, so convert it first with the HEIC to JPG converter. To make photos smaller before building the PDF use the image resizer or image compressor, and if the finished PDF must fit an upload limit, finish with the PDF compressor. To pull pages out of the result, use the PDF splitter.

Client-side privacy guarantee

All image-to-PDF conversion happens inside your browser using the pdf-lib library. Your images are never transmitted to any server — the PDF is built on your device. This makes the tool safe for sensitive documents: ID scans, medical records, financial statements, and legal documents can be converted to PDF without being logged, stored, or accessed by a third party. You can verify this yourself in two minutes.

Frequently asked questions

Can I add multiple images to one PDF?
Yes. Add as many images as you like and each becomes one page, in the order shown in the list. Use the up and down arrow buttons beside an image to reorder it, or the cross to remove it, then press Generate PDF. The file is always saved as images.pdf, so rename it afterwards if you need a specific name.
What page sizes are supported?
A4 (210 × 297 mm), A3 (297 × 420 mm), US Letter (8.5 × 11 in) and Fit to image. With Fit to image each page takes the picture's pixel size as its size, so a 4000 × 3000 px photo becomes a page about 55.6 × 41.7 inches, which prints huge but views fine. For fixed sizes you can choose portrait or landscape.
How do I convert a single image to PDF?
Add the image, choose the page size and fit, and press Generate PDF. For a PDF page that matches the picture exactly, pick Fit to image and set the margin slider to 0; the default margin of 20 points (about 7 mm) leaves a border and shrinks the picture slightly.
What do Contain, Fill page and Actual size do?
Contain keeps the whole picture visible at its own proportions, with blank space where the shapes differ. Fill page stretches the picture to the area inside the margins, so a photo that is not the same shape as the page looks distorted, it is not cropped. Actual size places the picture at its pixel size in points, which can be larger than the page or tiny.
Will my photos lose quality or make the PDF huge?
JPEG photos are placed into the PDF as they are, with no recompression: in a test, a 215 KB JPEG produced a PDF about 1 KB larger. A PDF of many photos is therefore about as large as the photos added together. PNG, WebP and GIF images are redrawn and stored as PNG image data, so their PDF size follows the pixel content. A 4000 × 3000 photo on A4 portrait at the default fit prints at roughly 519 pixels per inch, far more than needed.
Will phone photos come out sideways?
No. If a JPEG carries an orientation tag from the phone, the tool redraws it upright before placing it (saving it at 95% JPEG quality). JPEGs with no rotation tag are placed byte for byte. Check the preview thumbnail in the list: it shows the picture the way the browser reads it.
Can I convert iPhone HEIC photos to PDF?
It depends on your browser, because the tool relies on the browser to read each image. If it says it could not read a file, convert the photo to JPG first with the HEIC to JPG converter, then add the JPG. PNG, JPG and WebP work in current browsers.
How do I make a scanned-document PDF from phone photos?
Photograph each page flat and well lit, add the photos in page order, choose A4 portrait and Contain, and press Generate PDF. If the result is too large for an upload form, run it through the PDF compressor, which can aim for an exact size such as 200 KB or 2 MB. To combine it with typed documents, use the PDF merger afterwards.
Are my images uploaded anywhere?
No. The images are read and assembled into the PDF inside your browser with the pdf-lib library, and the PDF is created on your device. Nothing is sent to a server, so ID scans, medical records and contracts stay with you. There is no account, no watermark and no page limit beyond your device's memory.
