A designer sends you a .psd file, or you download a template, and double-clicking it does
nothing useful: Windows asks which app to use, the browser just downloads it again, and File Explorer
shows a blank icon instead of a thumbnail. PSD is Photoshop's own working format, with every layer
kept separately, and very little outside Photoshop reads it.
We went through it on 6 October 2026 on Windows 11 and Chrome 154, with real Photoshop files of every colour mode, and measured what the common workarounds do to the picture. The Mac notes at the end come from Apple's and Adobe's documentation, not from our own test.
Why Windows and your browser won't show it
Windows reads pictures through a built-in system of image decoders, the same one File Explorer uses to draw thumbnails. We asked it to open a PSD directly: it answered that no suitable imaging component could be found, while the same call opened a JPEG straight away. That is why there is no PSD thumbnail in File Explorer unless you install a program that adds a PSD thumbnail viewer.
Browsers are no different. We handed Chrome two PSD files under all three file types a website might
label them with (image/vnd.adobe.photoshop, image/x-photoshop and none): it could
not decode either of them as an image, so dragging a PSD onto a browser tab only downloads it again.
Three ways that work
| Method | Good for | Watch out for |
|---|---|---|
| PSD to PNG or PSD to JPG (free, in the browser) | Just seeing or sharing the picture, on any computer or phone, with nothing to install. PNG keeps transparency and can save each layer separately. | You get an image, not an editable PSD. |
| A free editor such as GIMP | Editing the layers yourself. | An install, and layer effects or text may not look exactly as in Photoshop. |
| Preview on a Mac | A quick look on a Mac. | Shows one flattened picture, no layers. Apple doesn't list PSD among Preview's formats. |
Step by step, without installing anything
- Open PSD to PNG (or PSD to JPG if the picture is going into an email or onto a website) and drop the PSD on it. It works the same in a phone's browser.
- The picture appears with a short report: which colour mode the file is in, how its colours were converted, and whether anything couldn't be drawn.
- Download the PNG or JPG. To take the design apart, choose Every layer as its own PNG: each layer comes out as a separate image, numbered from the bottom up.
The file is read inside the browser and not uploaded, which matters when it is a client's unreleased design.
It opens, but looks wrong
Blank, or "This layered Photoshop file was not saved with a composite image"
Besides its layers, a PSD normally stores one finished, flattened copy of the picture, and most programs that "open" PSDs only show that copy. Photoshop leaves it out when the option Maximize PSD and PSB File Compatibility is off, and then those programs show an empty image or exactly that sentence.
The PSD converters here notice the missing copy and combine the layers themselves. To see how close that gets, we removed the copy from real Photoshop files and compared the result with the copy Photoshop had saved: files of plain layers, groups and text matched on 100% of their pixels; a web page mock-up with a few drop shadows on 94%; a file built to show off eleven layer effects on only 6%. Photoshop draws layer effects as it displays the file, so they are missing from any rebuild, and the report names each layer that has them.
If it is your own file, the lasting fix is in Photoshop: Edit → Preferences → File Handling, set Maximize PSD and PSB File Compatibility to Always and save the file again. It makes the PSD larger, because the flattened copy is stored inside it.
Colours look dull or shifted
A PSD made for printing is usually CMYK: it stores ink amounts, not screen colours. Turning those into screen colours properly needs the colour profile that Photoshop embeds in the file, and simple converters skip it. On a landscape photo saved in the common U.S. Web Coated (SWOP) profile, skipping it put the colours an average of 24 and up to 56 steps out of 255 away from a colour-managed conversion. The PSD converters here use the file's profile and stayed within 2 steps.
A pale outline around a cut-out or logo
Photoshop stores the flattened copy of a transparent document as if it sat on white. Where an edge is half transparent, a little of that white is mixed in, and a converter that copies the colours as they are leaves a light halo that shows on a dark background. PSD to PNG takes the white back out: blended back over white, its output matched Photoshop's stored values on all 496,314 half-transparent pixels of our test file. For a PNG that already has the halo, see why is my PNG not transparent.
Large PSB files and 16-bit documents
PSB is Photoshop's version of PSD for documents over 30,000 pixels or 2 GB; it opens the same way. 16- and 32-bit documents are reduced to 8 bits per channel, which is all a JPG or an ordinary PNG viewer shows. What limits a browser is memory: an image much larger than about 16,000 by 16,000 pixels can be more than a browser will hold, and you get an error for that file rather than a broken picture.
