I've tried to save the TIFF to JPEG post-edits and that gets me down to around the 200MB range, then I open the JPEG to save to TIFF using no compression and the file size goes back to around 800-900MB. That bit confuses me too... Should a JPEG file saved to TIFF increase it...
I know too now, JPEG compression in a TIFF is not exactly the best choice (it's lossy, uncommon and rarely supported, besides a JPEG-compressed TIFF not any better then a regular JPEG file). However, our clients demand that. Let's see if the above is going to be a suitable solution...
JPEG compression is the most widely used image compression method because of its higher compression ratio and ideal compression effect. It uses a special lossy compression algorithm and deletes colors of images that is not detected easily by human eye, thus images can be compressed in a small st...
TinyPNG Smart PNG and JPEG compression (English) TinyPNG 智能PNG和JPEG图片压缩(中文版) TinyPNG做了什么? TinyPNG使用智能有损压缩技术将您的PNG文件的文件大小降低。 通过选择性的减少图片中的颜色,只需要很少的字节数就能保存数据。 对视觉的影响几乎不可见,但是在文件大小上有非常大的差别。 我为什么要使用...
网上有很多关于这方面的文章,可以找来看看。也可以直接找它的标准文档《The JPEG Still Picture Compression Standard》仔细读读,我敢保证,会很头疼的。 我们常说的JPEG图像,实际上是JFIF(JPEG File Interchange Format),版本号为1.02。这是由Eric Hamilton于1992年9月提出的,目前使用最为广泛。此外还有TIFF JPEG等...

is different than a JPG within a TIFF. When reading a file with JPG extension, i need to know the IDs and structure defined so that i can appropriately map the data into the structure and find out the properties of the image. What i am interested in is the compression type. With JPG...
TIFFs, using a lossless form of compression, are much larger. In fact, some TIFFs can reach up to 4GB in size. Transparency. A TIFF will support transparent image elements added during the editing process, such as hidden logos or watermarks, but JPEG files won’t. The short-lived JPEG ...
