optimizing a folder of images,
one of these image raise an error and entire process exits.
i suggest to keep optimization on other images.

This kind of tool usually has an optional command line available like this:
tool --output my_output_image.png my_input_image.png
This is very useful, especially in cases where you want to keep the original un-optimized file.
Another form would be
tool source_dir --output-dir destination_dir
where it is understood that all files found recursively under source_dir will be converted to the same dir under destination_dir.
I think it would be a good idea to change, especially as you are using Python >= 3.6.
I can put in a pull request if you wish.
This is a nice little utility which has saved me writing my own :) Thanks.
Would love to batch convert all pngs to jpgs and force delete original as part of my optimize/resize process. I tried using optimize-images -cb -fd ./ but it did not convert my pngs which were 660kb.
Hi
Can a option be added to create a log file for the optimized images.
optimizing a huge library of images,
one of this cannot be optimized.
i'm not able to understand what one.
i know the last optimized, but not the one working on.
this is the log

Brunsli is a lossless JPEG repacking library.
Brunsli allows for a 22% decrease in file size while allowing the original JPEG to be recovered byte-by-byte.
Is it possible to add support for it?
Describe the bug
The app skips pngs by default
In de readme it says: "tries to optimize each encoder's settings for maximum space reduction and applies the maximum ZLIB compression on PNG.", But in reality it just says:
🔴 [SKIPPED] redacted.png
----------------------------------------
Processed 1 files (1.2 MB) in 3.0s (0.3 f/s).
Optimized 0 files.
Average savings: 0.0 B per optimized file
Total space saved: 0.0 B / 0.0%
To Reproduce
Steps to reproduce the behavior:
Expected behavior
A smaller png
Desktop (please complete the following information):
After compressing, the resolution goes down - in my case from 300 to 72 (DPI) . Can you please allow an option for keeping the image resolution the same

Why this tool tried to use / directory to save temporary images?
Hello,
This issue is similar to #13
I try to use optimize-images cli on Ubuntu to recursively optimize images, it happens suddenly that I get this error:
PIL.UnidentifiedImageError: cannot identify image file
when I try to only optimize the image in question I get the same error, so the error is in the image itself, when I check its type and details I get that:
JPEG image data, JFIF standard 1.01, resolution (DPI), density 96x96, segment length 16, Exif Standard: [TIFF image data, big-endian, direntries=23, height=0, bps=0, compression=LZW, PhotometricIntepretation=RGB, manufacturer=Canon, model=Canon EOS 5DS R, orientation=upper-left, width=0]
# python -V
Python 3.6.10
# optimize-images -v
1.3.5
NAME="Ubuntu"
VERSION="16.04.5 LTS (Xenial Xerus)"
My question here, why the software refusing to optimize this image and how can I make it ignore and continue because if it finds an error it just stops, I want it to ignore that error and continue working on the rest.
Best regards,
Pyhton 3.10 is incompatible with pillow 8.2.0 as described here https://pillow.readthedocs.io/en/latest/installation.html
so it won't pip install.
Describe the bug
Installed this on an updated RaspiOS install on RPI Zero. Running the app tells me to install Pillow even though it's installed?
To Reproduce
Steps to reproduce the behavior:
Expected behavior
I expect to optimize the JPEGs in the given directory.

Hi, @victordomingos
After testing some images I found an interesting bug. If there are portrait images in directory then this tool turns them into landscape mode.
Any suggestions why it happens? 😺
Script crashes when it tries to process .pdf files in same folder as .jpg or .png - would be nice if it would just skip these and carry on.

There is no clear documentation what exactly this script does. If I run it on directory I see impressive optimizations, like twice better than what jpegoptim does, and way faster. But I'm afraid to run it over my photo collection, as I can't understand what it does to images. While it's pretty clear what jpegoptim does.
Can you please clarify in the docs what exactly it does to jpeg files if I run it on directory? Like "if image is bigger that 4000x3000 reduce it to 4000x3000", "strip all EXIF information" "apply lossless optimizations", etc.
The red dot, the green check mark, and the red triangle do not show up properly in the command line of Windows. (I'm referring to the screenshot in your README file.)
Can you use ASCII characters instead? Thanks.

i have bytes with JPG/PNG content and i whant optimize image in my application, most cases in memory

Hi,
Thanks for providing this useful tool, I'm using it to generate compressed images in NAS devices.
The 'piexif.load()' you used to get exif may raise a lot of different exceptions when exif head is broken(e.g. struct.error: unpack requires a buffer of n bytes). The program need to catch those, otherwise it will corrupted.
I accept images from camera iPhones, the HEIC images are so large, that I would like to optimize them before saving them to the server. Thank you
The tool (v. 1.3.5) fails on a big batch task upon encountering a single image with zero bytes file size. Wouldn't it be better for the tool to be able to log the issue and keep on converting the rest of the folder?
