  • Q: Is there a direct download link for IrfanView and Plugins?

A: Yes, the links are available since years on my website.

For IrfanView: see the IrfanView website: Other Download Sites and Scroll the the end of page (Alternative links) or click here .

For Plugins: see the Plugins page. Alternative link.

Some important infos:

1) Please take care when downloading IrfanView from software sites which are not listed on the Downloads page .

2) Some sites use custom/unknown downloaders which can contain malware or ask you to pay for a (free!) download.

3) The original filenames and SHA-checksums of IrfanView and Plugins installer are visible on the Downloads page.

  • Q: I want to create a CD-ROM with images and I will put IrfanView on the CD. How can I start IrfanView's Slideshow when I insert the CD in the drive?

    A: You can create either a self running EXE slideshow file (in the slideshow dialog) or you can copy the original files to the CD and use a TXT file. Read the help file page "How to start IrfanView slideshow from a CD?" for examples.

  • Q: Generic problem with video files: If I try to play some AVIs, I get the error message "Video not available, cannot find XYZ decompressor"!

    A: The correct video codec is not installed, please check this site for the right codec (see in menu Image->Information for the codec name):

    A good codec pack is the K-Lite Codec Pack. it contains the most popular video/audio codecs.

  • Q: How to reduce saved file size from XX to YY KB?

    A: There is no one-click solution for that, sorry.

    1. Open an image.

    2. Go to menu Image->Resize/Resample and reduce the image dimensions in pixels.

    3. Go to menu File->Save as, choose JPG and save as new file (see also JPG save options like: lower JPG quality, uncheck EXIF, etc.).

    4. Look at the file size of the new file. If still too big, repeat the steps, using smaller pixel size and/or lower quality, etc.

    X. For many images, use File->Batch Conversion, Advanced options.

    Note. since version 4.20, a new JPG save option has been allowed: Set file size. IrfanView PlugIns must be installed.

  • Q: Problem: Since yesterday, IrfanView shows all my images black/white! Why?

    A: The load option for JPGs "Load as grayscale" in 'Properties->JPG/PCD/GIF' is activated, please uncheck!

    Note: in the Save dialog, see JPG format save options. The option "Save as grayscale" must not be active.

  • Q: Problem: IrfanView can't read filenames/paths with chinese, japanese, polish etc. characters.

    A: Please activate the UNICODE PlugIn in Properties->Languages.

  • Q: How to use JPG lossless operations (Rotation, IPTC, Comment) in batch mode?

    A: Start the Thumbnail window, open the folder with JPGs, select many JPGs and see in thumbnail menu File for JPG Lossless Operations -> Lossless transformations with selected thumbs. Note: The auto-rotation option works only if the EXIF orientation tag is properly saved (not top-left).

  • Q: Is there a portable IrfanView version (for USB sticks, CDs etc.)?

    A: Yes, EVERY IrfanView version is portable. You can:

    1. Copy your existing/installed IrfanView folder to USB stick (recommended), or

    2. Use the normal installer and install IrfanView to an USB stick folder, or

    3. Use the ZIP version and unzip to a USB stick folder.

    A: Start IrfanView, go to 'Properties->Extensions' and associate your types.

  • Q: Problem: If I save some images as JPG and set the file size option. I receive a save error message. Why?

    A: You can't reach ANY possible file size using JPG compression. The JPG file/image can't be saved smaller than the JPG file/image with quality of 1. means there are certain limitations regarding minimal JPG file size. If you set a smaller file size than JPG (with quality of 1) can compress, you will get an error message. If you want to reach the desired file size, you have to resize the image first (reduce image dimensions in menu: Image->Resize) OR disable the file size option and save only using JPG quality.

  • Q: Why is RAW loading slow (Camera RAW formats, e.g. CR2)?

    A: This depends which RAW plugin options are used in 'Properties->PlugIns'. The preview option is the fastest, Half-size is fast and if both are deactivated: the full RAW image is loaded => very slow.

    A: Open Thumbnails window and load a folder. See thumbnails sort menu, use Sort by EXIF date.

  • Q: How to use Batch conversion/rename to sort result pictures in folders with date-taken in folder name?

    A: In the Batch dialog, you can use Placeholders in the name of the output directory. If you set a directory name like "C:\sorted images\$E36868(%Y_%m_%d)\", you will save the result files in folders with date-taken (format: YYYY_MM_DD) in folder name, like "C:\sorted images\2011_06_23\".

  • Q: How can I batch rename "JPG" files to "jpg" (lower case extensions)?

    A: In the Batch-Conversion dialog use the rename pattern: $N.jpg (Be sure you only have JPG files selected/added to the input list).

    A: In the slideshow dialog put/add MP3 files into the slideshow file list, usually at the begin or before an image. The MP3 file is played until it ends or until next MP3 is loaded from the file list. IrfanView PlugIns should be also installed, at least the MP3 PlugIn.

  • Q: Why is the saved JPG file much bigger than the original JPG file?

    A: The JPG file size depends primary on JPG save quality, in the Save dialog options. Normal quality is 75 or 80, higher values will produce larger result files.

    A: Most photo printing services use formats 3:2 or 2:3 (10x15 cm or 4x6 inches) for photos.

    If your images (e.g. from a compact digital camera) are 4:3 or 3:4 (see in Image->Info menu in IrfanView, Original size ratio), you should better crop the desired image area in format 3:2 or 2:3 and print the cropped image. The steps:

    1. Open the image in IrfanView (see Image->Info, see if the original size is not alredy 3:2 or 2:3).

    2. Go to menu: Edit->Create maximized selection. For landscape images use 3:2, for portrait images use 2:3.

    3. See the selection rectangle. If you want to move it, use either mouse (right mouse button click inside of the selection) or arrow keys on keyboard.

    4. When the selection is OK, use either menu: Edit->Crop and then File->Save-As or better: Options->JPG Lossless Crop, to save the selected image.

    5. Use the new file for printing services.

  • Q: How can I tag a file during browsing?

    A: See the Hotkeys help file page. Tag a file with X, untag with SHIFT+X, use SHIFT+Q to show all tagged files in Thumbnails window.

    SaveFormats = extension|extension|

    NOTE: If you leave the value text empty (no extensions), there save dialogs won't be used at all, so you can disable File->Save menus .

    Just write:

    SaveFormats = |

  • Q: I am an administrator. How can I set/update the IrfanView license for all users?

    A: Insert the license (and/or other admin options from above) to the global INI file (located in the IrfanView folder) and distribute it.

    2) If IrfanView is installed on local clients, start IrfanView in admin mode and insert the license. Distribute the global INI file, copy it to the IrfanView folder on local clients.

    Here is an example of a minimal INI file (5 lines only) for the IrfanView folder:




    Name=your license name
