problem: Huge file-size increase

Hi,
I have been trying out the EXIFeditor now and it works great apart from one significant problem.

When I edit Camera Make and Camera Model the file size increases MASSIVELY. if the original JPEG is 8Mb in size, it ends up being more than 9Mb after changing these tags.

Is it the software or me? When I try other programs they do not change the size like this.
I prefer the GUI of EXIFeditor and would really like to use this as my first choice.

Hello,

yes, this is true. File size is increased while saving. It is due to compression and quality settings set to relatively high parameters.You could open EXIFeditor.exe.config file from EXIFeditor directory and try tune that parameters. Its named JPEG_compression and JPEG_quality.

Have a nice day!

Many thanks, will try this

best regards

Seems to have solved the problem - Many thanks Pavel!

Two notes on the subject:
1. It seems that the "JPEG_compression" does not really affect the file size even when altering this figure from 20 (default). I tried up to 78 as compression and no significant change in size at all. However, altering the "JPEG_quality" worked fine.

2. If possible, I would suggest that future release include the the option to alter compression and quality in the GUI

again: Thanks /T

I have found a similar problem. I was updating the date tags and file size increased from 2.5 to 3.5 MB. I don't want to alter the JPG compression or quality level from the original image. Is it possible to do this? or perhaps include this in future versions.


Otherwise I am getting great results from the software and I love the batch processing ability as I am updating the data on thousands of photos.

Hello,

bad news is... file size is increasing always while is saved (with high quality settings). This is effect of recompression of picture using JPEG method. However you can alter compression level, recompression mechanism is always used so picture is become "worse". In my opinion optimum is to set 95%, picture is looking very good and file size is approx. same as original).

And good news is :-) ... I'm working on very new version of this application hardly. It is totally redesigned, has more features, for example supports TIFF and PNG files (not only JPEG), EXIF and IPTC tags modification, and mainly: lossless picture saving ability. Work is complete from cca 70%. See this phorum and web pages :-)
