JPG and other images to PDF

How to convert images to PDF

1. 1Select Choose files or drop your images on the page. Each image becomes one page.
2. 2Put them in order: drag an image by its handle, or use its arrow buttons.
3. 3Choose the Page size (Fit to image, A4 or Letter) and a Margin. For A4 and Letter you can also set the Orientation.
4. 4Select Convert to PDF (with several images it reads, for example, Convert 5 images to PDF), then Download PDF.

Options

Fit to image

The default. Each page is the size of its image at 96 pixels per inch, plus the margin. Very large images are scaled down to 200 inches on the longest side, the largest page PDF readers accept.

A4 and Letter

Each image is scaled up or down to fit inside the margin and centered on the page. Orientation Auto (the default) turns each page to match its image; Portrait or Landscape applies to every page.

Margin

No margin (the default), Small (12 pt, about 4 mm) or Large (36 pt, about 13 mm), on every side.

Image quality

JPG images go into the PDF byte for byte, without re-compressing, so there is no quality loss. PNG images are stored losslessly, and transparent PNGs stay transparent. Phone photos that were taken sideways are turned upright using their orientation tag, again without re-encoding the JPG. WebP, GIF (first frame only), BMP, AVIF and HEIC are converted once: to PNG when they have transparency, otherwise to JPEG at quality 92 (on a scale to 100).

Formats and limits

Input

JPG, PNG, WebP, GIF, BMP, AVIF and HEIC/HEIF.

HEIC

Safari opens HEIC itself. In other browsers, HEIC photos are decoded with libheif, open-source software licensed under the LGPL-3.0, loaded only when needed. Its license and source code are on the licenses page.

Size

Up to 100 MB per image. Images above 25 MB may be slow to convert.

Number of images

Up to 100 at a time on a computer, 50 on phones and tablets.

Output

One PDF, one page per image. It is named after the image (photo.jpg becomes photo.pdf), or images.pdf for several; you can change the File name before converting.

Troubleshooting

• “… is a HEIC photo that couldn’t be opened.” The file may be damaged, or the decoder didn’t load. Try again, or set your iPhone to save photos as JPG (Settings › Camera › Formats › Most Compatible).
• “… couldn’t be read.” The image is damaged or incomplete. Open it in an image viewer and save it again.
• “… isn’t a supported file” or “… is a PDF document.” Only images can be added here. To combine PDF files, use Merge PDF instead.
• “Your browser ran out of memory.” Large photos take a lot of memory while the PDF is built. Convert fewer images at a time, or use a computer.

How your data stays private

Everything happens in your browser, on your device. Your files and text are never uploaded, never stored, and never put in the address bar.

• The site’s security policy (connect-src 'self') tells your browser to block any attempt by the page to send data to another server.
• Only your preferences, such as the theme and a tool’s last-used options, are saved in your browser’s local storage. Never your content.
• To check it yourself, open your browser’s developer tools, select the Network tab, and use the tool: no request carries your data.

There is no account, no sign-up and no watermark. After your first visit, pages open without a connection; a tool’s larger parts, such as the PDF and image engines, are saved the first time you use it, so it works offline from then on.
