When you have a PSD but need an image
PSD is Photoshop's working format, full of layers, masks and adjustments. Designers send PSD files for banners, mockups, thumbnails, product shots and website sections. Templates downloaded from the web often come as PSD too. That's great if you have Photoshop, but most people who receive the file just want to look at it, approve it or use the final picture.
PNG is the right output for that. It keeps sharp text, logos and interface elements without the soft halos JPG can add, and it opens in any browser, phone, office suite or website builder.
How it works: the combined image
When Photoshop saves a PSD with the option “Maximize Compatibility” turned on, it also stores a flattened, combined version of the whole image inside the file, exactly as it looked when it was saved. ConvertirDocs reads that combined image and turns it into a PNG. The layers themselves aren't edited or rebuilt, so what you get is the final picture as the designer saw it.
If the file was saved without that option, it doesn't contain the combined image, and ConvertirDocs tells you clearly instead of producing a wrong result. In that case ask whoever made it to save it again with “Maximize Compatibility”, or to export a PNG directly. In Photoshop the option appears when saving and can be set to always in the preferences.
What PNG is good for here
Use the PNG to show a design to a client in a chat, to drop a banner into a presentation, to upload a thumbnail or a product image, or to keep a lightweight preview of an archive of PSD files. For a photo-heavy design where file size matters more than perfect edges, PSD to JPG produces a much lighter file.
Need the picture smaller? Send the PNG to “Resize image” to set a width and height, or to “Compress image” to reduce its weight. Need it with no background? “Remove white background” works for designs on a plain white background.
Private and free
The conversion runs in your browser. Your PSD files, which often contain unreleased designs or client work, are never uploaded to a server or stored. There's no account, no watermark and no limit on how many files you convert.
The PNG files carry no EXIF data, so camera and software details aren't copied into them.
