#Batch resize jpegs how to
We’ll walk you through how to create a custom Photoshop Action which will resize an image to a predetermined width, then we’ll apply that action to an entire folder of images with just a few clicks.
"C:\IrfanView\i_view32.exe" "C:\photo\C0692B\*.jpg" /ini="%Temp%" /advancedbatch /convert="C:\photo\C0692B\test\*.Batch Resize an Entire Folder of Images in Only 2 Minutesīatch resizing is ideal for when you need to send a client several images for review but full-size files aren’t necessary. This has the advantage of being independent on what by default used i_view32.ini currently contains on settings. I decided to find out how all these options are saved in INI file of IrfanView to be able to write a batch file which creates dynamically i_view32.ini in folder for temporary files for the batch image conversion task. checked Try to save with original JPG quality (estimation)Īll those settings are written to i_view32.ini and can be used with /advancedbatch from command line.checked Keep original EXIF data (if JPG to JPG).let Apply changes to all pages (TIF/PDF saving) checkedĪll other advanced options are not checked.checked Save files with original date/time.selected Method 2: Set total canvas dimensions in pixels.checked Canvas size, clicked on button Settings.checked Use Resample function (better quality).checked Preserve aspect ratio (proportional).I did following in the opened large dialog window: Then I enabled Use advanced options (for bulk resize.) and clicked on button Advanced.
I clicked first inside IrfanView in menu File on menu item Batch Conversion/Rename. However, it is also possible to proportional resize images to 1840 x 1840 pixels with canvas the resized image for example with white border on top/bottom or left/right depending on width and height of original image using advanced batch conversion mode. If the images are needed for a web gallery in 1840 x 1840 pixels, reference each image from within a DIV or TD element with a width and height of 1840 pixels and define that the image is displayed centered horizontally and vertically within the element. I do not recommend to resize each image with a too low height or width to 1840 x 1840 pixels to get only square images with "blank" area on top and bottom side on an image with a too low height or "blank" area on left and right side on a too small width. "C:\IrfanView\i_view32.exe" "C:\photo\C0692B\*.jpg" /resize_long=1840 /aspectratio /resample /convert="C:\photo\C0692B\test\*.jpg"Īn image with 1920 x 1200 pixels has an aspect ratio of 1920 / 1200 = 1.6 and therefore the resized image has 1840 x 1150 pixels. There are the options /resize_long=x and /aspectratio for this purpose. width is higher (or equal) than height.įor images in portrait format it is most likely better to resize the height to 1840 pixels with keeping the aspect ratio of each image. It looks like you want to resize each JPEG image in a folder to a width of 1840 pixels with keeping aspect ratio for images in landscape format, i.e. The text file i_options.txt in program files folder of IrfanView lists and explains all options supported by IrfanView on the command line.
