IrfanView Support Forum.

Drag the image link to any Toolbar in Opera 12.17 and Drop it while holding shift to add a button to launch IrfanView 64-bitIrfanView is a favourite Freeware Program of countless users. As the name indicates, it is an image viewer, not a photo-editor (the IrfanPaint plugin can do basic editing), but it can do most common tasks, and many things that you might not expect, like batch-renaming of any files. See the History of Changes for a complete list of the latest new features. I describe a few of them below.

For those new to IrfanView, this page gives an overview of the menu options. Please take a look at the Tutorials for help on common tasks.

If you are an experienced user, I hope you will discover some new features that you overlooked.

Though I have been an enthusiastic user for many years, in putting together this web page, I discovered options I never knew existed.

If you think that you know the program well, have a look at the file called i_options.txt, which is in the program folder. You will find a long list of command-line parameters for IrfanView.

64-bit Version

The 64-bit version can handle larger images, but unless you need to work with very large images (over 25 Megapixels) it is recommended to use the 32-bit version. Not all plugins are available for the 64-bit version. Not all PlugIns are ported (yet) to 64-bit (like OCR) and some 32-bit PlugIns must be still used in the 64-bit version, some with limitations (see the "Plugins32" folder). The Unicode and many Adobe 8BF PlugIns cannot work on 64-bit.

The two versions must be installed in different folders, and the right set of plugins must be installed for each version.

The multipage preview dialogue is useful if you work with multipage images — it makes it much more convenient for finding particular pages.

Some improvements to the insert text dialogue let you preview the text before adding it to the image, and there are some effects for the text such as transparency or partial transparency.

Similarly, there’s an option to preview a watermark before applying it to the image. This two little changes are worthwhile.

Support for DXF images has been added via a plugin. I guess that’s useful if you’re looking for a particular drawing in a folder of images. Converting vector images to bitmaps would not be very high on my list of priorities. Better to open them in DrawPlus where you can edit them before exporting to a bitmap format at the resolution you need. I am sure the results would be much better if Super-sampling was used. Thin lines tend to drop out unless the resolution is very high.

Exif thumbnails can now be updated when saving images. One user thought it was a security risk since someone in a photo that had been cropped would still be visible in the Exif thumbnail. I’m not sure that I agree, but anyway now the thumbnail will be updated to reflect the changes made during editing.

The Resize and Custom Selection dialogues now have an option to add user-defined sizes to the list of Standard Sizes. This could save some time.

The save dialogue also has an option to save profiles, so you could for example have different profiles for saving images for the web, for print, or for making backups of edited images.

Change Batch Order

When performing more than one action during batch operations, the advanced batch dialogue now offers an option to change the order in which the operations are performed, e.g. crop first then resize, or resize first, then crop, etc.

Watermark Images

Insert an image with transparency into an image or selected area to add a watermark or overlay to an existing image. Adjust the position relative to the corners of the selection or the image, and adjust the transparency to make the watermark more subtle or to make it stand out more.

Zoom to Cursor

Zoom in with the image centred on the mouse pointer when using the scroll wheel.

Estimate JPG Quality

On saving a JPG image, there is now an option to estimate the original compression/quality ratio use to create the original image, and to use that in place of the slider value. If an image was previously compressed at a quality of setting of 50, there is nothing to be gained by increasing the quality to 100 — all that will do is increase the file size. Saving again with the original value will give optimal results.

Fixed Zoom Values

In Options, Properties, Zoom/Colour Management it is now possible to enter a series of fixed values to zoom to when zooming in and out. Up to 50 values between 3 and 4,000 can be entered in the table.

Face Detection

This plugin will scan a folder full of images and quickly filter out only those images that contain people. Not 100% reliable, but it is quick and finds images with faces in most cases.

WebP Support

This format developed by Google improves compression and reduces artefacts for photographic images. WebP images  are significantly smaller but better quality, than an equivalent JPG image. Opera uses WebP format for its Opera Turbo proxy server due to its relatively good quality when using very high compression. Google Chrome and Opera support WebP images, as do most browsers on the Mac.

Getting Started

The author's preference is for function over form, and minimalist commands. Where most programs use Ctrl Key combinations, IrfanView often uses an alphanumeric key alone, or one with shift. Selection is done by dragging a marquee with the mouse in the usual way. The cursor then changes its form and function as you move it across the marquee. Grab the sides with the arrows to resize the mask, or click with the magnifying glass to zoom in. Right click to move the selection.

Enter or double-click will switch to full-screen mode, where the left and right mouse buttons or the cursor keys will browse through all supported files in the current folder. Enter or Escape will return to window mode.

Plus and minus on the Numeric keypad will zoom in or out. Right mouse will show the hand cursor for panning the image or moving a selection.

The Thumbnail Browser

When you open the thumbnail browser, the left window shows the folder tree. As soon as you click on a folder, IrfanView starts generating thumbnails for the files in that folder. Thumbnail generation is very fast, but the process can be interrupted if necessary.

Images can be moved or copied with the mouse or opened at full size in IrfanView. They can be sorted by name, type, size, or date, in ascending or descending order. After selecting several thumbnails, you can run a slideshow, combine them in a single image, make an html page that displays the thumbnails and links them to the full images, create a contact sheet, open the batch process dialogue to perform the same changes on them, or print them all as single images.

For sound files it will just generate icons, for TrueType fonts, and Text Files, it will generate a miniature preview. MP3 and WAV files can be played via Plug-Ins, TrueType fonts open with a user defined text sample, text files can be opened too, but are converted to B&W graphics at 96 dpi.
