How to convert an JPEG image to PDF

1. Upload the JPEG file

   Drop a .jpeg into the "Image file" field. JPEG support depends on the build of Sharp on the server; if decoding fails the tool will say so.

2. Pick a page size

   "Page size" offers Fit (page sized to the image plus a margin), A4 (210×297 mm, image centred), or Letter (8.5×11 in, image centred).

3. Set the margin

   "Margin (points)" is whitespace around the image, 0–72 (default 24). One PDF point = 1/72 inch, so 24 ≈ 8.5 mm of breathing room.

4. Press Run

   Output is a single-page PDF with your JPEG placed on it (filename jpeg-to-pdf.pdf). One image per PDF page — the tool does not stitch multiple JPEGs into one document.
