What happens when you convert PSB to PNG
- ImageMagick, the open-source image toolkit, reads the flattened copy of the whole picture that Photoshop saves inside every PSB, the image you see with all layers visible, on our conversion server, and saves it as a lossless PNG.
- Layers are not exported one by one: the result is the finished picture. A PSB saved with Maximize Compatibility turned off in Photoshop may have no usable flattened copy, and then comes out blank; resave it with that option on.
- Transparent areas stay transparent.
- This conversion runs on our server: the file is uploaded, converted, and deleted together with the result as soon as the result has been sent back to you. Nothing is kept. Files up to 25 MB are accepted.
How to convert PSB to PNG online
- Press "Choose PSB files" and select one or more files, or drag them onto the box. Files up to 25 MB each can be converted.
- There are no settings to choose: the converter keeps everything the target format can hold.
- Press "Convert to PNG". The file is uploaded to our conversion server, converted in a few seconds, and deleted together with the result as soon as the result is sent back.
- Save each PNG with its download button. Our server has already deleted both your PSB and the PNG by then.
Why convert PSB to PNG?
PSB files usually come from panoramas, billboards, large prints and very high-resolution scans. People convert them to PNG because PNG keeps sharp edges, text and transparency without any loss.
In short, PSB is good at what it was made for, and PNG is the more practical choice when the file has to open, upload or print somewhere else. PSB does not open in browsers; Photoshop opens it, and Photopea reads it, while PNG opens in every browser and image viewer.

About PSB and PNG files
What is a PSB file?
PSB is the big brother of PSD, added in Photoshop CS: the same layers and features, but images up to 300,000 pixels a side and files larger than 2 GB. Far fewer programs open it than open PSD.
What is a PNG file?
PNG compresses without losing a single pixel, so screenshots and text stay razor sharp, but a photograph saved as PNG is often three to five times the size of the same photo as JPG.
PSB to PNG not working? Common problems
- "Files up to 25 MB can be converted." Server conversions have a size limit. Save the image at a smaller size first.
- "The conversion took too long and was stopped." Very long or complex files can pass the 90 second limit. Split the file and convert the parts.
- "This file is not really in PSB format." The converter checks every file before it runs anything, so a file of another format renamed to .psb is refused. Choose the page for its real format.
Convert PSB to PNG from the command line
ImageMagick does the same on your own computer:
magick input.psb[0] output.pngConverting on your own computer keeps the file entirely local, which is worth it for very large or very sensitive documents. For everything else, the converter on this page does it without installing anything.
PSB to PNG converter FAQ
Will I lose quality converting PSB to PNG?
No. PNG is stored losslessly, so every pixel of the flattened picture is kept. The separate layers are not.
Why is the PNG a different size from the PSB?
Usually much smaller than the PSB, because only the flattened picture is kept, without the layers.
Are my PSB files uploaded?
Yes, for this conversion. A faithful PSB to PNG conversion needs ImageMagick, the open-source image toolkit, which cannot run in a browser. The file travels over an encrypted connection, is converted in a private temporary folder, and is deleted together with the PNG as soon as the result has been sent back to you. We do not keep, read or share it.
Can I convert several PSB files to PNG at once?
Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open a PNG file?
PNG opens in every browser and image viewer. PNG is common for screenshots, logos, diagrams and anything with transparency.
Is this PSB to PNG converter free?
Yes. There is no sign-up and no watermark. Because this conversion uses our server, there is a fair-use limit of 25 MB per file and a number of files per hour, which stops the service being overloaded.
Can I convert PSB to PNG on my phone?
Yes. It works in Safari on iPhone and iPad and in Chrome on Android. The conversion happens on our server, so it is as fast on a phone as on a computer; the PNG is saved to your Downloads folder.
