What this converter does
JPG to PDF places each image you add on its own page and saves all of those pages as one PDF, in the order shown in your list. It accepts JPG/JPEG and PNG files. JPG images are embedded exactly as they are — not re-compressed — so the PDF keeps the full quality of your photos.
Because the pages are pictures, text in a photographed document won't be selectable or searchable in the resulting PDF. The tool does not perform text recognition (OCR).
When converting images to PDF is useful
- Documents photographed with a phone. Receipts, signed forms, ID copies requested by an employer, or handwritten notes are easier to share and file as one PDF than as a string of photos.
- Portals that only accept PDF. Many application and claims systems reject image uploads.
- Multi-page scans saved as images. Some scanners save each page as a JPG; converting joins them into a proper document.
- Printing a set of photos or screenshots. A PDF with a fixed page size prints predictably on standard paper.
How to convert JPG to PDF
- Add your images. Drop several JPG or PNG files at once, or add them in batches. Each shows a thumbnail so you can confirm it's the right picture.
- Arrange the order. Page order follows the list, top to bottom. Use the arrows to move an image and × to remove it.
- Choose a page size. US Letter (the default) or A4 for printable documents; Auto to make every page exactly the shape of its image.
- Create and download. Select Create PDF, then download
images.pdf.
Page size, orientation and image quality
US Letter vs A4
US Letter (8.5 × 11 in) is standard in the United States and Canada; A4 (210 × 297 mm) is used almost everywhere else. Pick the size of the paper the recipient is likely to print on. With either option, each image is scaled to fit inside a small margin (about a third of an inch) and centred, keeping its proportions — nothing is cropped or stretched.
Orientation
Letter and A4 pages are created in portrait orientation. A landscape photo placed on a portrait page is shrunk to fit the width, leaving white space above and below. For landscape images — slides, screenshots, panoramas — choose Auto, which gives each page the same shape as its image.
What "Auto" does
Auto sets the page to the image's pixel dimensions, with no margin. It looks perfect on screen, but a large phone photo produces a physically large page, so printers will need "fit to page". Use Letter or A4 if the PDF is meant for printing.
Image quality and resolution
The PDF can only be as sharp as the images you give it. On Letter or A4, small images are enlarged to fill the page and may look soft; as a guide, an image about 1,700 pixels wide or more fills a letter-size page at a comfortable reading resolution. On the other side, full-resolution phone photos make large PDFs — often several megabytes per page.
PNG transparency
Transparent areas of a PNG show the white page behind them. Logos or signatures with transparent backgrounds therefore appear on white, which is usually what you want.
Tips for a better PDF from photos
- Photograph documents flat and in good light. Shadows and angles can't be corrected by conversion. Fill the frame with the page.
- Crop before converting. Use your phone's photo editor to crop away the table or background; the page will look cleaner and the file will be smaller.
- Convert HEIC, WebP or other formats first. Only JPG and PNG are accepted. On iPhone you can set the camera to "Most Compatible" or export a photo as JPEG.
- Too big to send? Run the PDF through Compress PDF in Extra mode, which re-encodes the images at a lower resolution.
Common problems
- A photo appears sideways in the PDF
- Phones often store photos in one orientation and use a hidden "rotate on display" tag. Photo apps honour the tag, but the image data placed in the PDF may not, so a picture can appear turned. Fix it in seconds with Rotate PDF → "Selected pages", or rotate and re-save the photo before converting.
- "Only JPG and PNG images are supported"
- Other formats (HEIC, WebP, GIF, TIFF, BMP) were skipped. Convert them to JPG first.
- "… couldn't be read as an image"
- The file is damaged or its extension doesn't match its content (for example, a HEIC file renamed to .jpg). Re-export it as a genuine JPG.
- The PDF is very large
- JPGs are embedded at full quality, so twelve 4 MB phone photos make a PDF of roughly 48 MB. Resize the photos first, or compress the finished PDF.
JPG to PDF FAQ
No. The images are read and placed into a PDF by JavaScript in your browser. They are not sent to our server as part of the conversion.
Yes. JPG, JPEG and PNG files are supported and can be mixed in one PDF. Other formats such as HEIC or WebP need converting to JPG first.
JPG images are embedded without re-compression, so they keep their original quality. The PDF can look soft only if a small image is enlarged to fill a Letter or A4 page.
US Letter for recipients in the US or Canada, A4 for most other countries, and Auto when the PDF will mainly be viewed on screen or the images are landscape.
Not with this tool. It doesn't perform text recognition (OCR), so the pages are images. Use dedicated OCR software if you need searchable text.
No fixed limit. Each image must be under 150 MB, and very large batches of full-resolution photos may be slow on phones because everything is processed in your device's memory.
