How to use it
Add your pictures, then arrange them: the list order is the page order, and each picture can be moved up or down, rotated left or right, or removed; one click sorts by file name, which helps with numbered scans. Pick a page size (A4, A3, A5, Letter, Legal, or a page that matches each picture exactly), orientation (automatic follows each picture), a margin and whether to enlarge small pictures to fill the page or only shrink large ones. Then create the PDF and check the page previews before you download it.
JPG files are placed into the PDF exactly as they are, with no second round of compression, so there is no quality loss and creating the PDF is fast. PNG files keep their transparency, and other formats are converted through your browser first. Phone photos carry an orientation flag that PDF viewers ignore, so the tool reads it and rotates the picture to match. If the result is too big for an upload form, the option to make the PDF smaller re-compresses pictures to at most 1800 pixels at 80 percent quality.
The PDF holds pictures, not text, so it cannot be searched or copied from; this tool does no text recognition. Everything is built on your device and nothing is uploaded. To shrink the finished file use the PDF Compressor, to join it with other PDFs use Merge PDF, to take pages out use Split PDF, and to prepare pictures first use the Image Compressor or the Image Resizer.
Supported formats and limits
| Input | JPG, PNG, WebP, GIF, BMP and AVIF where your browser opens them. Up to 100 pictures. |
|---|---|
| Pages | One picture per page, in the order shown. Move up/down, rotate left/right, remove, or sort by file name. |
| Page size | A4, A3, A5, US Letter, US Legal, or the size of each picture (no white space). |
| Layout | Automatic, portrait or landscape; margins 0–100 mm; fit the page or only shrink pictures that are too big. |
| Quality | JPG files are embedded as they are, with no re-compression. An option re-compresses pictures (max 1800 px, 80%) for a smaller PDF. |
| Not included | No OCR: the PDF contains pictures, so its text cannot be selected or searched. |
Practical examples
Several phone photos of a document
- Situation
- Drop the photos, put them in page order, choose A4 with a 10 mm margin and create the PDF.
- What to expect
- One PDF with one page per photo, each fitted to the A4 page. Portrait and landscape photos get matching page orientation when Orientation is Automatic.
A PDF under an upload limit
- Situation
- Phone photos give a large PDF, so tick “Make the PDF smaller”.
- What to expect
- Pictures are re-compressed to at most 1800 pixels and 80% quality, which usually cuts the PDF substantially. The result shows the final size.
A photo that is sideways
- Situation
- A picture appears rotated in the list.
- What to expect
- Phone photos are shown the right way up using their orientation data. Use the rotate buttons if one still needs turning; the preview of the finished PDF confirms it.
The numbers behind it
scale = min(printable width ÷ picture width, printable height ÷ picture height)1 px = 0.75 pt (96 dpi screen pixels), 1 mm = 2.835 pt, A4 = 595.28 × 841.89 pt
- Printable area = page size minus the margin on every side
- PDF points are 1/72 inch
Each picture is scaled to fit inside the printable area of its page and centred.
Honest limits
- Each picture becomes one page; pictures are not split across pages.
- The PDF contains pictures only, with no selectable text.
- Up to 100 pictures per PDF; very large sets may exceed your device's memory.
