- 100%of processed files opened in Adobe Photoshop with the same layers and identical pixels
How it works
It packs your layers tighter
Photoshop saves some layers with an outdated compression algorithm. Layersqueeze uses a newer compression method that Photoshop already uses, so the pixels come out identical while taking up less space.
It removes a copy Photoshop doesn't need
Layersqueeze removes a full-size flattened copy of your image which Photoshop doesn't need. If you use Lightroom Classic or other apps that need it, turn this off in Options.
It verifies that everything is preserved
Before you download, Layersqueeze opens the new file and compares every layer with the original. Your original is never changed. How we test.
Other ways cost you something: flattening loses your layers, downsizing loses detail, and most online compressors upload your file, and some flatten it. Every way to shrink a PSD, compared.
Questions
Is it really free?
Yes, for personal and commercial work, with no sign-up, watermark, or limit.
Is it safe to compress PSD files online?
Yes. Most online compressors upload your file to their server, but Layersqueeze compresses it right in your browser. You can verify this by turning off your internet with this page open and compressing your file. We never see your file. Visit our privacy page for more.
Does compressing a PSD lower its quality?
No, there's no quality loss. Every pixel stays identical, and layers, groups, masks, smart objects, type, adjustment layers, and effects all stay as they were. Layersqueeze never changes your original: it makes a new copy and checks it against the original before you download it.
What exactly does it change?
Layersqueeze stores 8-bit layers with zip instead of Photoshop's run-length compression, which is usually the biggest saving. It clears a hidden list of every document ever pasted or placed into the file, which can reach megabytes. And it drops the flattened copy that Maximize Compatibility saves, just as Photoshop does when that setting is off. These options can be turned off before you compress.
Does the file stay small after I edit it in Photoshop?
Until you save it again. So use Layersqueeze on finished files: archives, backups, cloud storage, and files you send. For files you're still working on, set Maximize Compatibility to Never in Photoshop's File Handling preferences (what that setting does).
Which files shrink the most?
8-bit files saved with Maximize Compatibility on. Files that are 16 or 32-bit shrink less, because Photoshop already compresses them well, and so do files saved with Maximize Compatibility off, since there's no flattened copy to remove. Files that are mostly embedded smart objects shrink less too, since Layersqueeze keeps their contents as they are.
Which apps can open the result?
We test every result in Adobe Photoshop 2026, GIMP 3, and Krita 5.3. Lightroom Classic and InDesign need the flattened copy, so turn off "Drop the flattened copy" for files headed there. For any other app, try one file before you do a whole folder.
How big a file can it handle?
Files up to 1.2 GB work today, PSB files included. Bigger files don't fit in a browser tab yet, and we're working on it.
