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
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.
How much smaller will my file get?
+
That is decided by the content, not by the tool. Photographic detail and film grain resist compression; flat colour, text and silence collapse. A realistic expectation is a large reduction on anything with big uniform regions and a modest one on a busy photograph or a high-motion clip.
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.
What do I get back, and can I control the trade-off?
+
A single compressed file per input, at a quality or bitrate level you choose rather than a fixed default. If the result is not small enough, changing the dimensions or the duration will do more than pushing the quality slider further down.
What can I upload to Compress PSD?
+
Photoshop PSD documents, including ones with layer groups, layer masks, adjustment layers and blend modes. You do not need a Photoshop licence to work with them here.
Is there a file size limit on Compress PSD?
+
Yes: free accounts process images up to 25 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.
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.
Does Compress PSD cost anything?
+
No. Compress PSD is free and needs neither an account nor an Adobe subscription. Your PSD is deleted from the workers shortly after the job completes.
