#COMPRESS FILE SIZE IN PHOTOSHOP FULL#
Using the white layer only gets rid of the full preview image, and not the individual layer images. 1 First place to look is always Adobe Help available from the Help Menu. if you want to create the smallest PSDs possible and you don't care about the preview in OSX or wherever, just enable compatibility mode.
#COMPRESS FILE SIZE IN PHOTOSHOP ZIP#
In rare cases it can be ZIP compressed too. Depending on the size of the layer, this will be also stored as RLE or as the raw color channel values with no compression. The PNG file is available for download once the compression is complete 4. The max size of each file cannot be more than 3MB 3. You can upload up to 10 images at a time for bulk compression. Drag and drop the PNG files you want to reduce in size. Basically, each row of the image becomes 1 instruction that contains the color channel value and the width of the image.Īlso, when compatibility mode is enabled, every single layer also has image data that is stored in the PSD file (albeit without layer styles applied). Open TinyIMG PNG copressor on your web browser 2. By applying a solid white layer on top of everything, you are using the optimal condition for encoding the image with RLE. If you have added any layer masks to your image, you can apply them to the layer to reduce the file size. So, if you have 10 pixels in a row that have the exact same amount of red in them, it can compress them in a such a way that says, "hey, the next 10 pixels are red value 230" instead of storing "230 230 230 230." and so on. Adding a white layer decreased the file size from 177 MB to 164 MB. This preview image is encoded with RLE (run-length encoding), which optimizes the amount of data based on repeating color channel values. When I open with Photoshop and do 'Save As > PNG 24' and choose the compressed file size of the two options (the other being no compression) I still get an image that is on the order of a few MB, which, since it is going to be a web asset, I would like to be in the KB and not the MB's. When compatibility mode is enabled, the PSD file format stores the full sized preview image at the end of the file, which is used by apps to show a preview of the PSD (even if Photoshop isn't installed). To enter values in a different unit of measurement, choose from the menus next to the Width and Height text boxes. If you're going down this route, then you might as well disable compatibility mode.
