I’ve noticed it in my right-click contextual menu in Windows Explorer, but I’ve always glossed over it. If you’re like me and have been using SnagIt solely for its primary function- capturing and annotating screenshots-then you’ve never even used the Snagit Batch Image Conversion Wizard. Jpeg only supports 8bit color.If you’ve never used Snagit, I recommend you stop reading this article and go grab a trial of Snagit now so you can follow along with the steps below. Sane PNG ins 8bit color the is no need for 16bit color on the web. For Animated Gif you can reduce the number of frames. The are some third Party Plug-in available for saving PNG files that claim to save smaller file them Adobe does. So the First to do is make sure you web image have been sized to fit into web pages and their meta data has been stripped, With Jpeg images you can give up more image quality by reducing the image quality setting used when you save for web. Web sites image are Normally resample way down in So they do not need to be scale done in size to fit in a web page via html and also have their metadata striped so small file will be saved so the will transfer quickly over the network. The easiest way to produce smaller file is to resample you image down in size reduce the number of pixels you have for an image. Some File type encoding sacrifices Image quality to produce smaller files. The number of bits per pixels per channel 1bit 8bit, 16bit 32bit ![]() The Number of Channels of Pixel data image mode - bitmap, Grayscale, RGB, CMYK The Number of Pixels you have for an image. So the biggest factors contributing to file size are. ![]() Image with great fine details will not compress as was as a picture of a white wall. How well the image encoder compress the pixel data the smaller the file will be. The bulk of data in all image file type is Pixel data. Is there a better way that I've overlooking? The small files actually get bigger while the large ones get smaller, so the overall sum of all files is roughly 25% larger.ĭoes anyone have any suggestions on how I could fix this and end with smaller files? I'm beginning to think the only way is to manually target the largest images. Since my initial tests showed that large files were getting smaller, I suspect that this is happening because there are so many more small files (under 72ppi) than there are large files (over 72ppi). The big problem is that by converting all the images to 72dpi while maintaining their original size actually makes the sum of the images 25% larger in file size, largely defeating the whole point. PDFs and PSD files also present minor hiccups, but those don't necessarily need to be downsized anyways. Slows the process a bit, but not a huge deal since there aren't many GIFs. However, a setting prompt comes up for animated GIF files then, rather than overwriting them like it does other image files, it makes a copy in which the animation is broken. Doing that with the settings shown below, I've managed to get it to maintain the file name, file structure, and file type. I cloned the image files and set it up to open, modify, and save over the cloned files. Thank you so much for your help guys! We're almost there I think. ![]()
