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
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 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.
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 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.
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 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.
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.
Why does a MP3 site host Compress PSD?
+
MP3.to is built around the format that made portable audio ordinary: universally playable, small enough to ignore, and lossy in a way that only matters if you keep re-encoding it. Audio jobs cluster: the same person who needs a format changed usually needs the file cut, levelled or made smaller in the same sitting. Putting Compress PSD behind the same upload, the same caps and the same account is what turns three tabs into one.
What should I do with the result once Compress PSD is finished?
+
The converter on this site moves audio between MP3, WAV, FLAC, M4A, OGG and Opus, so the output format is a decision you can leave until the end rather than commit to at the start. Doing that after Compress PSD rather than before means the encode happens once, on the file you actually settled on, instead of twice.
Is Compress PSD here the same tool the sibling sites run?
+
The engines are shared — the same ffmpeg build, the same workers, the same limits. What a MP3 site adds is a point of view about bitrates, about what survives an encode and about when a lossless intermediate is worth the upload time. It also starts from one fact about the format this site is named after: MP3 frames are fixed-size blocks, so a cut lands on a frame boundary and gapless playback markers do not survive a re-encode.
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 listened to and nothing is indexed. Free accounts exist for history and batch size, not for access.
