JPEG, the same format as JPG
JPEG and JPG are the same image format. The only difference is the file extension: this page saves your file as .jpeg, while the PSD to JPG converter saves it as .jpg. The pixels, the compression, and the way the file opens are identical. Use whichever extension your workflow, upload form, or naming convention expects.
This tool converts a Photoshop PSD to JPEG entirely in your browser. You choose the quality and the background color, and the original file is never uploaded anywhere.
Why two extensions exist
The format is named after the Joint Photographic Experts Group, the committee that published the standard in the early 1990s, so .jpeg is the full, natural spelling. Older versions of Windows and DOS limited file extensions to three characters, which shortened it to .jpg. Mac and Unix-style systems never had that limit and often kept .jpeg. Both spellings were in wide use by the time the limit disappeared, and both are still around.
Under the hood they share one media type, image/jpeg. A browser, phone, or editor treats a renamed file exactly the same way, so renaming photo.jpg to photo.jpeg (or back) is safe.
When the .jpeg extension actually matters
Most of the time it doesn't. It does matter in a few practical situations:
- A website, CMS, or form that validates uploads against a list of allowed extensions and only lists
.jpeg - A script, build pipeline, or template that looks for files by exact name, such as
cover.jpeg - A project or client style guide that specifies one extension for consistency
- A teammate or tool that sorts and filters files by extension
If none of these apply, either extension is fine.
How to convert a PSD to JPEG
- Upload your PSD. Drag it into the upload area or select it from your device. The converter lists its dimensions, color mode, and layer count.
- Make sure JPEG is selected as the output format. It's the default on this page.
- Set the quality with the slider (10–100%, starting at 90%).
- Choose the background that will fill transparent areas: white, black, or a custom color.
- Adjust the size if you want a smaller or differently shaped image.
- Click Convert to JPEG and download your
.jpegfile.
How JPEG compression works, in plain terms
JPEG divides an image into small blocks and stores each one as a combination of smooth patterns instead of individual pixels. It then discards the finest variations first, because the human eye is more sensitive to changes in brightness than to subtle shifts in color. The quality slider controls how aggressively that detail is thrown away.
At high quality the loss is invisible. As you lower it, the same trade-off starts to show up as blockiness in flat areas, ringing (faint halos) around sharp edges and text, and color smearing where saturated colors meet. Knowing what to look for makes it easy to judge the preview.
| Quality | Typical result | Use it for |
|---|---|---|
| 90–100% | Artifacts essentially invisible | Final deliverables and close inspection |
| 75–85% | Looks the same at normal size, much smaller file | Web and app images |
| 60–70% | Softer detail, faint blockiness on edges | Email and quick previews |
| Below 60% | Clearly visible compression damage | Only when file size is critical |
Transparent areas become a solid color
JPEG has no way to store transparency. Before encoding, the converter fills every transparent pixel with the background you picked. White is the safest default for documents and light pages, black suits dark layouts, and a custom hex color lets you match a brand or page background exactly. Semi-transparent edges, like a soft shadow, blend into that color, so choose it based on where the image will be displayed. If transparency has to survive, export a PNG instead.
Getting the best JPEG from your PSD
- Export from the PSD, not from another JPEG. Re-compressing an already compressed image stacks up losses.
- Resize before you convert. Setting the final dimensions in the converter gives a smaller file than exporting at full size and shrinking it later.
- Keep text-heavy designs at high quality. Thin type and one-pixel lines show artifacts first. For screenshots or interface designs, PNG is often cleaner.
- Hide unwanted layers in Photoshop before saving. The export reflects the flattened composite stored in the PSD.
- Save the PSD with Maximize Compatibility. Set Preferences > File Handling > Maximize PSD and PSB File Compatibility to Always so other programs can read a flattened version of the design.
Troubleshooting
- The JPEG is blank or looks wrong. Re-save the PSD with Maximize Compatibility enabled and try again.
- Colors are slightly off. Browsers work in RGB, so CMYK and Lab documents are converted for screen. Converting to sRGB in Photoshop first lets you preview the exact result.
- The file is too large. Reduce the dimensions, then lower the quality in small steps.
- The converter reports the file is too large or complex. Use a desktop browser, close other tabs, or remove unused layer groups from the PSD.
