To convert a photo to JPG, open the image in a photo editor or image viewer, choose Save As or Export, select JPG or JPEG, choose a high-quality setting, and save the result as a new file.
Do not overwrite the original. Keep the source image in its existing format until you have opened and reviewed the new JPG.
JPG is a practical choice for family photographs because it can be opened, shared, displayed, and printed using almost any modern device. Our complete guide to digitizing and preserving family photos explains how file format fits into a larger preservation plan.
Heirloom’s professional photo-scanning service scans printed photographs at 600 DPI and delivers them as widely compatible JPG files.
What Is a JPG File?
JPG is a digital image format commonly used for photographs. The name comes from the Joint Photographic Experts Group, which developed the compression standard.
Files may use either of these extensions:
- .jpg
- .jpeg
JPG and JPEG refer to the same image format. The shorter .jpg extension became common when older computer systems limited file extensions to three characters.
JPG works especially well for photographs because it can store millions of colors while reducing file size through compression. This makes JPG files easier to:
- Download
- Upload
- View on televisions
- Store on phones and computers
- Share with relatives
- Add to digital photo collections
Nearly every modern operating system, browser, photo-printing service, and image application supports JPG.
Why Convert a Photo to JPG?
You may need to convert a photo when its existing format is not accepted by a website, device, printing service, or family member’s computer.
Common source formats include:
- HEIC or HEIF: Frequently created by newer phones
- PNG: Common for screenshots and graphics
- TIFF: Used for archival masters and professional imaging
- RAW: Unprocessed camera data requiring development
- BMP: An older, often large bitmap format
- WEBP: Frequently used for website images
- PDF: May contain one or more scanned photographs
Converting to JPG creates an accessible copy without requiring everyone to use specialized software.
The best workflow is to retain the source file and create the JPG as a separate viewing copy. This is especially important for RAW and TIFF files, which may contain more image information than the exported JPG.
How to Convert a Scanned Photo to JPG
Most scanning software can create a JPG directly.
Before scanning:
- Clean the scanner glass.
- Place the photograph squarely on the scanning surface.
- Select color scanning, even for sepia and black-and-white prints.
- Choose 600 DPI for printed photographs.
- Select JPG or JPEG as the output format.
- Use a high-quality setting.
- Scan and inspect the completed image.
- Save a backup before editing.
Three hundred DPI is generally fine for ordinary documents, but printed photographs should be scanned at 600 DPI. The additional resolution provides more flexibility for cropping, enlargement, and restoration.
If the scanner offers a compression slider, avoid the lowest-quality or smallest-file setting. Heavy compression can introduce blocky areas, halos, smearing, and loss of fine facial detail.
