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.
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.
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.
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.
Why would a modern-format site run Compress PSD?
+
WEBP.to is built around the modern replacement for both of the old defaults: one format that does lossy, lossless, alpha and animation, and reliably lands smaller than the JPEG or PNG it came from. People arrive here having decided the old defaults are costing them bandwidth, and that decision immediately raises the rest: what size, what quality, what happens to the transparency. Compress PSD is on the same upload and the same account so those questions get answered in one place.
Once Compress PSD has run, what is worth doing next?
+
The converter on this site moves images to and from WebP, PNG, JPG and AVIF, which is where you decide whether a smaller file is worth losing the older browsers. Doing it in that order matters: pick the pixels first and the container afterwards, because the container is the cheap decision and the pixels are the expensive one.
Do the sibling sites run something different?
+
The engines are identical — same libraries, same workers, same caps. What is different is the opinion attached, and the opinion here rests on a property of the format this site is named after: the same .webp extension can hold a lossy VP8 frame, a lossless one, or an animation, so the sensible processing path is decided per file rather than per extension.
What happens to my file, and is an account required?
+
No account, and nothing is retained: uploads are deleted from the workers shortly after the job finishes, and nothing is inspected, listed or indexed. Accounts exist for history and batch size only.
