Host a PSB file and share it as a link
Put a Photoshop large document online at its own address — for files beyond PSD's limits.
Drop your PSB file here
Any other file works too — up to 25.0 MB, or 100.0 MB for a whole site
Free to use. Your PSB file is live at your-name.99helpers.site in about ten seconds.
What is a .psb file?
PSB is Photoshop's Large Document Format, for files that exceed PSD's limits of 30,000 pixels per side or 2 GB. It's what panoramas, billboard artwork and very large composites end up in.
What people use PSB files for
- Gigapixel panoramas
- Billboard and large-format print artwork
- Complex composites with many layers
- High-resolution matte paintings
What opens a PSB file
- Adobe Photoshop
- Affinity Photo, with some limitations
- Nothing else reads PSB reliably
How to host a PSB file
- 1
Drop your PSB file in
Drag it onto the box at the top of this page, or click to choose it. Files up to 25 MB are supported, and nothing is uploaded until you publish.
- 2
Pick an address
Type a name and we'll tell you straight away whether it's free. That becomes the link: large-composite.99helpers.site
- 3
Publish and share
Create a free account — that step exists so the file is yours to update, replace or delete — and the link is live within seconds.
The same three steps work for any file — see how file hosting works on 99helpers.com.
What happens when someone opens the link
The file downloads. PSB files are usually far larger than any web upload limit, so this suits smaller examples rather than production files.
Why host a PSB file instead of emailing it?
PSB files are large by definition, so most exceed the 25 MB limit here — for those, this isn't the right delivery route.
Worth knowing before you publish
- Most PSB files are far over 25 MB; flattened exports or crops are what fit.
- Host a JPEG preview so people can see the artwork without Photoshop.
- Save as PSD if the file is actually within PSD's limits — support is much broader.
PSB hosting questions
- What's the difference between PSB and PSD?
- PSB handles documents beyond PSD's 30,000-pixel and 2 GB limits. Below those, PSD is the better choice for compatibility.
- Can I host a large PSB?
- Probably not — the limit is 25 MB per file and PSB files are large by definition. Host a flattened export instead.
- What opens PSB?
- Photoshop, and Affinity Photo with some limitations. Support is narrower than for PSD.
