JPG to PDF
Put a JPEG photograph on one PDF page for review or printing. Its existing image data is embedded, but the PDF does not provide photo-editing controls.

Format Overview & Applications
A client who does not use the photographer’s editing software can review the image in a document; the photographer can still return to the JPEG for cropping or retouching.
Technical Specifications & Codec Breakdown
JPEG and JFIF inputs are passed through to the PDF writer as JPEG bytes, then embedded as a JPEG image; no second JPEG quality setting is applied.
OS & Browser Compatibility
A photographer can open the original in a photo editor to change exposure, while a client can review the page in a PDF reader without needing JPEG-specific software.
Useful info
Rotate and crop the photograph before conversion if its EXIF orientation or framing matters; this route embeds the JPEG stream directly.
Format Comparison & Technical Specifications
A 6000×4000 client-proof JPEG would occupy a 40×26.7 inch page when placed at 150 dpi.
Frequently Asked Questions
Does the conversion recompress the photograph?
The PDF writer embeds the JPEG image data rather than making a new JPEG export, so there is no additional quality slider on this route.
What page size does a 6000×4000 photo make?
At 150 dpi, it occupies 40×26.7 inches, with the original landscape proportions.
