Reduce PSD file size — instantly, in your browser

Photoshop bloats .psd and .psb files with excessive XMP metadata (DocumentAncestors, rdf:Bag, rdf:li) that can grow to hundreds of megabytes. This tool strips that metadata while keeping every layer, mask, and pixel intact.

How it works

  1. 1

    Drop the file

    Pick a .psd or .psb file from your computer. Nothing is uploaded — processing happens locally in your browser via WebAssembly.

  2. 2

    Strip the bloat

    Excessive XMP metadata (DocumentAncestors, rdf:Bag, rdf:li) is removed from the file and any embedded smart objects.

  3. 3

    Download the result

    Layers, masks, and pixel data stay byte-identical. Only the metadata changes — Photoshop opens the file as before.

FAQ

Are my files uploaded anywhere?

No. The tool runs entirely in your browser — the file you choose stays on your device and is never sent to any server.

Will my PSD still open in Photoshop?

Yes. The tool only removes excessive XMP metadata fields (DocumentAncestors, rdf:Bag, rdf:li). Layers, masks, smart objects, and pixel data are preserved byte-for-byte.

Why are my PSDs so large in the first place?

Recent versions of Photoshop accumulate ancestor identifiers in XMP metadata each time a file is saved or copied. These identifiers serve no purpose for you and can grow to hundreds of megabytes over time.

Is there a size limit?

Browsers cap a single tab’s memory at roughly 2–4 GB. The tool loads your file into memory, so files up to ~1.5 GB usually work. For larger PSBs, use the command-line version.

What about .psb files?

Supported. PSB uses 64-bit offsets internally — the engine handles both .psd and .psb.
