Keep the originals separate and select only images for the same purpose. First, try the settings with 2 or 3 images, and if there are no problems, process the entire file and check the contents of the ZIP.
Group only images with the same purpose
Batch processing applies the same settings to all images. If you mix photos and logos, portrait and landscape formats, print formats and SNS formats, the appropriate settings will differ and you are likely to make mistakes.
Divide groups by purpose, such as ``Product photos to WebP'' and ``Submitted photos to 1600px width.'' Do not change the original folder, but change the output destination.
Choose one from compression, conversion, and resizing
Compression adjusts the image quality while keeping the original format, and format conversion unifies JPEG, PNG, and WebP. When resizing, align the width to the specified width and calculate the height from the original proportions.
Rather than performing multiple processes at the same time, it is easier to judge the results by focusing on one purpose in one execution.
Try it on a few and then try it all
First, select two or three photos with different characteristics and check the results with bright photos, dark photos, and images with text. If the settings match, the rest will be processed at once.
If the image is very large or there are a large number of images, the device memory will be used. If processing stops, try dividing the number of images and closing other tabs and apps.
Unzip the ZIP and check it
The completed files will be compiled into pixel-toolbox-batch.zip. Don't just save the ZIP, unzip it and check the number of files, format, height and width, and quality of several images.
If even one file contains an unsupported format or exceeds 25MB, an error message will be displayed with the file name. Remove or convert the offending image and try again.
Contents that can be selected in batch processing
The current implementation performs the processing sequentially within the browser and only collects the output into a ZIP.

Batch image processing
You can compress multiple JPEGs, PNGs, and WebP files at once, convert them, unify the width, and save them as a ZIP file.
Batch image processing→This article gives general guidance. If a recipient, printer or official service provides its own requirements, follow those requirements first.
