LZW compression: smaller and faster to transfer!
TIFF is the format of choice for saving important images. It is the common commercial and professional image standard. However TIFF images are generally large and therefore will take longer time to transfer. MisterClipping.com has a tip for this issue. TIFF images optionally use LZW compression, it is the compression of a file into a smaller file using a table-based lookup algorithm invented by Abraham Lempel, Jacob Ziv, and Terry Welch. Lossless means that there is no quality loss due to compression, it guarantees that you always can read back exactly what you saved, bit-for-bit identical, without data corruption. This is a critical factor for saving master copies and important images. Image programs of any stature will provide LZW, but simple and free programs often do not pay LZW patent.
How to apply the LZW compression?
- Open your TIFF file in Photoshop. Click 'Save as' and choose 'TIFF format'. you will then get the following dialogue window:
- Then you can transfer your TIFF file to our website or FTP server, your images will be clipped and returned to you exactly as we received them. After dowloading the images, you can open the file in Photoshop, save the file as TIFF and uncheck the LZW compression.
