Pictures of any kind in one PDF
Screenshots, scans, diagrams and photos turn into one PDF with a page per picture. This page starts with A4 pages, the size most offices and schools expect; switch to US Letter, or to pages the size of each picture, above the Merge button.
| Picture | How it goes into the PDF |
|---|---|
| JPG | Copied in as it is, without compressing it again |
| PNG, BMP | Stored without loss; black-and-white scans with one bit per pixel |
| TIFF | Every page of a multi-page TIFF (fax and scanner files), without loss |
| WebP, GIF | The picture (for an animation, its first frame), without loss |
| HEIC, HEIF, AVIF | Decoded and turned upright, then stored without loss |
Transparent parts of PNG, WebP and GIF pictures become white paper, as they would when printed.
Order and layout
Pictures appear in the order of the list: drag them into place, use the arrow buttons, or click Sort by name. On A4 and Letter pages each picture is centred and turned to a landscape page when it is wider than tall. Pictures are shrunk to fit the page but never enlarged, so a small icon or signature stays at its own size instead of turning into a blurry full page. The 1 cm margin option adds white space around each picture.
Scans keep their size
A scanned page that records its resolution (for example 300 dpi) is sized from it. With Same as the picture, a scan of an A4 letter prints as A4 again, and a scanned receipt stays receipt-sized.
Limits
Each picture may have up to 100 megapixels, and up to 100 files and 5,000 pages go into one PDF. Pictures that can't be read are left out with a note, and the rest are still converted.
