Save edited photos as PSD when you want to keep editing layers, as TIFF when you need a high quality finished master or print file, and as JPEG when you are sharing online or by email. Each format has a clear job, and many photographers use all three for different stages of the same image.

PSD: The Working File
PSD is the Photoshop document. It keeps layers, masks, adjustment layers and text separate, so you can return later and change anything. The cost is large file sizes and limited support outside Adobe programs. Use it while a project is active or when a client may ask for revisions.
TIFF: The High Quality Master
TIFF stores image data with little or no loss, supports 16 bits per channel and is readable by almost every editor and print service. Files are large, though lossless compression helps. Use TIFF for final masters, for sending files to a printer who asks for them and for scans.
JPEG: The Sharing File
JPEG uses lossy compression to make small files. At high quality settings, the loss is difficult to notice, and every browser, phone and social site handles it. The weakness is that repeated saving degrades detail and it holds only 8 bits per channel, which limits heavy editing. Use it as a final delivery format, not as a master.
Comparing Them
| Need | PSD | TIFF | JPEG |
|---|---|---|---|
| Keep layers | Yes | Sometimes | No |
| Quality loss | None | None with lossless | Yes, adjustable |
| File size | Large | Large | Small |
| Compatibility | Adobe focused | Very broad | Universal |
| Bit depth | 8, 16 or 32 | 8 or 16 | 8 |
A Practical Save Routine
- Keep the raw original unchanged.
- Edit and save a layered PSD, or the layered format of your editor.
- Export a 16 bit TIFF for the finished image if you want a master or plan to print.
- Export a JPEG at a high quality setting, such as around 80 to 90 percent, sized for the screen or platform.
- Use the sRGB color space for web JPEGs, since it displays most consistently across devices.
These numbers are general guidance. Adjust to the needs of your printer or website.
Mistakes to Avoid
- Flattening and overwriting your only layered file, which removes the chance to revise later.
- Exporting a web JPEG at full camera size when a smaller version loads faster and looks the same on screen.
- Saving print files in a small color space and losing range your printer could reproduce.
FAQ
Can I edit a JPEG again and again?
You can, but each save adds more compression damage. Work from a raw file or TIFF and export a new JPEG each time.
Do I need all three formats?
Not always. If you never revisit layers, skip PSD. If you only post online, a high quality JPEG may be enough, though keeping raw originals is wise.
The Short Version
PSD is for editing, TIFF is for masters and printing, and JPEG is for sharing. Match the format to the job and keep your raw files safe.
