<div dir="ltr"><div class="gmail_default" style="font-family:trebuchet ms,sans-serif">I love PNG for many things. But when dealing with Raw portability sometimes a Tiff is needed. The real challenge is what is your end goal and what are you looking to do with it. I acutually use JPG to protect my images from full theft because only i have access to the 100% RAW image. my Jpg's at best go our as 80 of the original and at most 1/4th the resolution. 4000x6000 rendered to 1080x1920</div><div class="gmail_default" style="font-family:trebuchet ms,sans-serif"><br></div></div><div id="DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><br>

TIFF does have a compression option,<br>
<br>
PNG is a lossless compression, not unlike a ZIP archive, but with an efficient compression algorithm. Though not a perfect analogy, 1 pixel <= 3 bytes. PNG also supports an alpha layer (transparency), which isn't important unless you want it to be.<br>
<br>
For example, I just took a screenshot of my desktop. Screen resolution is 1920x1080 @ 32-bit, so 8,294,400 bytes of pixel information are required (1920x1080 pixels * 4 bytes per pixel (RGB values + alpha value)) . The corresponding PNG came out to 1,969,094 bytes, whereas an equivalent TIFF with built-in compression is 2,371,201 bytes. An uncompressed TIF is 8,294,843 bytes, slightly larger than the raw pixel information.<br>
<br>
There may be use cases where TIF is a better option, but for the lay person, PNG is better.<br>
<br>
