JPG to PDF takes one or more images and turns them into a single PDF, one image per page, in the order you set. It accepts JPG, PNG and WebP files. JPEG data is copied into the PDF as it is, and PNG pixels are stored losslessly, so each picture keeps its full resolution. You can let every page match its image, or center each image on a standard page such as A4 or Letter with a margin.
The PDF is built entirely inside your browser with JavaScript. Your photos, scans and screenshots are never uploaded, so there is no transfer to wait for and nothing is left on a server when you close the tab. The tool checks the actual bytes of each file rather than its extension, so a JPEG that was saved with a .png name still works. Up to twenty images at a time, each up to 100 MB.
The result is a PDF of pictures, not a text document. If you convert a photo of a printed page, the words cannot be searched or selected; run the file through OCR PDF afterwards for that. WebP files are re-encoded as JPEG on the way in, so transparent areas turn white, quality changes slightly, and a WebP over about 16 million pixels is scaled down. Other formats such as HEIC or GIF are refused when you select them.
How to use JPG to PDF
- 1Click Select files, or drop your JPG, PNG or WebP images onto the page. Use Add more files to add others later.
- 2Drag the images into the order you want, or use the up and down arrows. Each image becomes one page.
- 3Under Page size, keep Match each image, or choose Fixed page size and set Paper (A4 by default), Margin (pt) (24 by default) and Orientation (Auto, Portrait or Landscape).
- 4Optionally change the Output file name; the default is images.pdf.
- 5Click Create PDF from N images, then click Download images.pdf (or the name you chose) to save the file.
Frequently asked questions
- Does converting reduce the image quality?
- Not for JPG files: their bytes are copied into the PDF unchanged, so resolution and compression stay exactly as they were. PNG files are unpacked and stored losslessly, so every pixel is preserved even though the bytes are repacked. WebP images are re-encoded as JPEG at a high quality setting first, because the library that builds the PDF can only embed JPEG or PNG data, and any transparent areas become white.
- What is the difference between Match each image and Fixed page size?
- Match each image makes every page the same size as its picture, one point per pixel, so a high-resolution photo becomes a large page that viewers zoom to fit the screen. Fixed page size scales each image to fit inside a standard sheet with the margin you set and centers it, which is the better choice if you plan to print.
- How big will the PDF be?
- For JPGs, roughly the total size of the images you added, since their data is stored as-is rather than compressed further. PNGs are repacked losslessly, so they can come out a little larger or smaller than the originals. If the file is too large to email, run it through Compress PDF afterwards.
- Can I search or copy the text in the PDF?
- Not from this tool alone. The PDF contains only the pictures. Open the result in OCR PDF to add a searchable text layer over each page; it currently reads English text only.
- Are my photos uploaded anywhere?
- No. The PDF is assembled on your own device with JavaScript, and the images never leave your browser.
- Can I add images to a PDF I already have?
- Convert the images here first, then use Merge PDF to combine the new file with the existing document in whatever order you need.
