JPG to PDF – Combine Images into One PDF

How to convert JPG images to PDF

Add images by clicking the dashed box or dragging them onto it. JPG/JPEG and PNG files are accepted; anything else is skipped with a message that lists the skipped names.
Add more if you like. Each new batch is appended to the end of the list.
Check the order. Images become pages from top to bottom. Remove an image with the × button; to move one, remove it and add it again at the end.
Press Convert.
Download images.pdf.

How the images become pages

The conversion runs in your browser with the open-source pdf-lib library. For each image the tool creates one page and draws the image across the whole page, without margins. How the image is stored depends on its format:

JPEG data is embedded exactly as it is. There is no re-compression, so quality is identical to your file and the PDF is roughly as large as all the JPEGs together.
PNG images are decoded and stored with lossless compression. Transparent areas stay transparent and show as white in most viewers. The PDF can be somewhat larger or smaller than the original PNG.

Each page is exactly the size of its image, at one PDF point per pixel. A PDF point is 1/72 inch, so a 1200 × 1600 pixel photo becomes a page of about 16.7 × 22.2 inches (42 × 56 cm), and a 3024 × 4032 phone photo a page of 42 × 56 inches. On screen this makes no difference, because viewers zoom to fit. When printing, choose "Fit to page" or "Shrink to printable area" and the aspect ratio is kept. Images of different sizes produce pages of different sizes in the same PDF.

Tips for a clean result

Fix sideways photos first. Phones often save pictures in the sensor's orientation plus an "orientation" tag that galleries obey. This tool does not read that tag, so such a photo can appear sideways in the PDF. Rotate it in an editor that rewrites the pixels – exporting or "saving as" a copy usually does – and add the copy.
Crop and resize before converting. A 12-megapixel photo of a receipt is far more than needed. Resizing to around 1500–2000 pixels on the long side keeps text readable and the PDF much smaller.
Photos as JPEG, screenshots as PNG. JPEG suits photographs; PNG keeps screenshot text crisp.
Number the files (01.jpg, 02.jpg …) so they are easy to select in the right order.
iPhone photos: HEIC files are not accepted. Safari on iPhone often hands photos to web pages as JPEG automatically; if a .heic file is rejected, convert it first or set Camera → Formats → Most Compatible for future photos.

Common uses

Bundling receipt photos for an expense report.
Turning phone snapshots of a paper form or homework into one document.
Collecting screenshots for a bug report or a how-to.
Sending a small portfolio or a set of scanned drawings as a single attachment.

Limitations and alternatives

Formats: only JPEG and PNG. WebP, HEIC, GIF, TIFF and BMP need converting first.
No page-size or margin options: pages always match the image. For A4 or Letter pages with margins, insert the pictures into a word processor and export to PDF, or on a Mac open the images in Preview and print them to PDF.
No text recognition: the PDF contains pictures, so its text cannot be searched or copied. An OCR tool is needed for that.
Memory: dozens of full-resolution photos can exhaust a phone's memory; resize them or convert in batches and join the results with Merge PDF.

Frequently asked questions

Which image formats can I convert?

JPG/JPEG and PNG. Other formats such as WebP, HEIC, GIF or TIFF are skipped and need to be converted to JPG or PNG first.

Will my photos lose quality?

No. JPEG images are embedded without re-compression, and PNG images are stored losslessly.

Why is the PDF page so large when I print it?

Each page takes the pixel size of its image at 72 points per inch, so large photos make large pages. Choose "Fit to page" in the print dialog to print them on standard paper.

Why is one of my photos sideways?

The photo relies on an orientation tag that this tool does not apply. Rotate the photo in an editor, save a copy and add that copy instead.

How do I change the order of the images?

Pages follow the list order. Remove an image with the × button and add it again at the end, or number the files before you add them.

Can I add margins or use A4 pages?

Not with this tool; each page matches its image. A word processor or your operating system's print-to-PDF function can place images on standard pages with margins.

Are my images uploaded?

No. The PDF is built inside your browser with pdf-lib and saved directly to your device.
