1Drop your PSD files into the box above, or pick them from your device — there is nothing to install and no account to create.
2Choose how hard to squeeze: a quality or bitrate target, and optionally smaller dimensions if size matters more to you than detail.
3Start the job and let the workers re-pack the file; your original is never modified in place.
4Compare the new size against the original, then download the compressed PSD file.
Compress PSD FAQ
Does the format of my file change how much I can save?
+
Very much so. PSD is Photoshop native — layers, masks, adjustment layers and blend modes stay live and editable, which no flat image format can represent. That determines both the headroom available and whether the saving costs you anything in fidelity.
Is there anything specific to PSD I should know before compressing?
+
Yes — layers, masks and adjustment layers are live objects rather than pixels, so a tool either preserves them or composites them down — there is no middle option. It is worth knowing before you overwrite an original you might need again.
What is the most common mistake when compressing PSD files?
+
Compressing the same file repeatedly. Each pass on a lossy format is a fresh generation of loss and the savings shrink while the damage accumulates. Go from the original to your target in one step, and keep the original.
How does Compress PSD actually make the file smaller?
+
Concretely, the composite and the layer data are recompressed with RLE or ZIP so the document still opens in Photoshop with its stack intact; the large win, if you want it, is flattening, and that is a deliberate choice rather than a side effect. Nothing about it depends on you installing software: the job runs server-side and hands back a finished file.
Can I run Compress PSD on several PSD files at once?
+
Yes, though layered documents are the heaviest thing in the image family to decode, so a batch of large PSDs takes noticeably longer per file than the equivalent JPGs.
Do layers, masks and text stay editable?
+
Only if the output is itself a layered format. A flat image format cannot represent a live layer, an editable text object or an adjustment layer, so those are baked into the result. Keep your original PSD — the output is a deliverable, not a replacement master.
Is there a file size limit on Compress PSD?
+
Yes: free accounts process images up to 5 MB each, and layered documents reach that faster than anything else in the image family because every layer stores its own pixel data. A working PSD with dozens of layers can exceed that easily; flattening a copy in Photoshop first, or converting to TIFF, is the usual way around it.
Will Compress PSD lower the quality of my PSD files?
+
Pixel data in a PSD is stored losslessly, so nothing degrades. The real question is structural: whether the result keeps the layer stack or arrives as a finished composite. Anything that has to produce a flat image applies blend modes, masks and opacity exactly as Photoshop previews them.
Why does a Word site host Compress PSD?
+
WORD.to is built around the editable end of a document's life — the DOCX that is still being written, still being styled and still being argued over, before anyone flattens it for sending. Office files are containers full of other people's media — images, embedded audio, fonts — so the work people need on them is usually the work they would need on those contents anyway. Compress PSD shares the upload, the caps and the account with the conversions for that reason.
What should I do with the result once Compress PSD is finished?
+
The converter on this site takes documents out to PDF for sending, to images for embedding and to plain text for anything that has to read them programmatically, and back the other way. Doing that afterwards keeps the editable original around, which is the part you cannot get back once it has been flattened.
Is Compress PSD here the same tool the sibling sites run?
+
The engines are shared — the same document toolchain, the same workers, the same limits. What a Word site adds is a view on what survives leaving the Office format and what does not, which is the question every one of these jobs actually turns on. It also starts from one fact about the format this site is named after: the document is a zip of XML, so text edits are cheap and the weight is almost always the embedded images.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploads are deleted from the workers shortly after the job finishes, nothing is read and nothing is indexed. Free accounts exist for history and batch size, not for access.
