Compress PSD Files for Sharing
A layered PSD can run to hundreds of megabytes, far too much to email or post for review. This tool takes the merged image Photoshop stores in the file and saves it as a compact JPG (or PNG to keep transparency), so clients and colleagues can see the design without Photoshop. Your PSD and its layers are not changed.

Frequently asked questions
Can it make the PSD itself smaller?
No. Shrinking a PSD while keeping its layers means deleting hidden layers, rasterising smart objects or cropping in Photoshop. What this tool makes is a lightweight flat copy for sharing.
Why does the copy look different from Photoshop?
It uses the composite saved with Maximize Compatibility. If that option was off, only the small thumbnail is in the file; re-save the PSD with it on, or export from Photoshop directly.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
