Spørgsmål og svar om billedbehandlingsprogrammet (gratis) IrfanView


  • 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 Videos (AVI, MP4 etc.), I get the error message like "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):
    Codec-Guide (install K-Lite Codec Pack)
    All Codecs and Decompressors – Video Codec Definitions
    A good codec pack is the K-Lite Codec Pack, it contains the most popular video/audio codecs.
  • Q: Batch mode: How to convert/save all input files (even from different folders) back to original folders?
    A: The Batch dialog text field "Output directory for result files" can contain a real folder path and/or placeholders (see the Help file, Options->Text pattern page).
    Use the $D placeholder/text as result directory, which is the placeholder for the original file folder.
    Take care, you can overwrite all input files! You can combine conversion+rename and set a new filename to avoid overwriting.
  • 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 fullscreen mode shows wrong image parts on Windows 10. Why?
    A: Your screen DPI value is not 100%. IrfanView doesn't support all DPI scaling features on Windows 10 yet. Fix: right mouse button click on IrfanView, Properties, Compatibility. Activate the option "Override high DPI scaling", use "Scaling performed by Application".
  • Q: How to use JPG lossless operations (Rotation, IPTC, Comment, Rebuild EXIF thumbnail) 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.
    (Note: the ZIP version of IrfanView is always available on the website link Other download sites at the bottom of the page).
  • Q: How can I set IrfanView as my default viewer?
    A: Start IrfanView, go to 'Properties->Extensions' and associate your types.
    NOTE: in newer Windows versions, you must start IrfanView in ADMIN mode to change file associations. Use right mouse click on IrfanView, use the "Run as admin" menu and verify. If still not working, use the system Control Panel: Set default programs/apps.
  • 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.
  • Q: Why are some edit menus or the red eye menu greyed out?
    A: Many edit options or red eye reduction works on selections only. Create first a selection (outline rectangle) in the image using the left mouse button.
  • Q: How to sort pictures by date-taken?
    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 images2011_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).
  • Q: How can I add background sound for automatic slideshow or EXE/SCR?
    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 I can't scroll a large, zoomed (larger than screen) image in fullscreen mode using arrow/page keys?
    A: Either is the image not really larger than screen or the option Properties->Browsing/Editing->Jump to next image … active, please uncheck.
  • Q: I downloaded IrfanView (or PlugIns) but when I start it, I get the message "This is not a valid Win32 application"?
    A: This message is shown for damaged/incomplete EXE files, probably a download error. Download again, try another mirror or location.
  • 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.
  • Q: Is IrfanView compatible with Windows 10/Windows 8/Windows 7/Vista/XP 64 bit?
    A: YES, like probably 95% of all 32 bit programs.
  • Q: How can I create selection with exact size or ratio?
    A: See in menu: Edit->Create custom crop selection (or other selection menus).
  • Q: How can I prepare my photos (format 4:3 etc.) to be correct (no cropping or white edges) when using a Photo printing service?
    A: Most photo printing services use formats 3:2 or 2:3 (10×15 cm or 4×6 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 already 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: "File->Selection as" (same as: "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.
  • Q: How can I insert another image into the current image?
    A: First copy a picture (which should be inserted) to clipboard, e.g. in another IrfanView instance. Now open the right image, use mouse to select a rectangle (or use: Edit->Create custom selection) and if you now use: Edit->Paste, the image from clipboard will be inserted into selection. In properties->editing, you can set to fit or stretch a pasted image into selection.
  • Q: Why are IrfanView Thumbnails images not clear?
    A: See in Thumbnails Windows options menu/dialog. Deactivate the option 'Load EXIF-Thumbnail for JPGs'.
  • Q: If I start IrfanView the system asks me each time about the start as Administrator, why?
    A: Somebody, not IrfanView, set the program properties to "Run as administrator". Disable this option (right click on IrfanView icon/EXE, Properties, tab: Compatibility) and run IrfanView normally. Actually, no option should be selected in the Compatibility tab for IrfanView.
  • Q: How can I change the icon for IrfanView associations?
    A: Go to Properties->Extensions (start IrfanView with "Run as admin") and choose the Icons button. Here you can set other icon(s) for associated file types.
  • Q: Problem: The icons on my desktop are wrong, all show IrfanView/Firefox/etc. icon. How can I fix that?
    A: This is usually a problem with the LNK file association, not caused by IrfanView. Go to Google and search for e.g "LNK association fix". You will probably get several hits for sites offering a REG file for LNK fix. Here are some sites:
    1) LNK fix for Windows 7:
    2) Microsoft Knowledge Base
    3) How to Rebuild the Icon Cache in Windows Vista and Windows 7
    4) A Utility to Unassociate File Types in Windows 7 and Vista
    5) File association fix for windows 7
    6) Default File Type Associations – Restore
  • Q: Batch conversion: How can I save result files in the original/source folder (even if files from several input subfolders are used)?
    A: There are 2 methods:
    Method 1) Set the value for the batch destination folder (output directory) to: $D (placeholder for original file folder).
    Method 2) Use Advanced batch options, activate the option Create subfolders in destination folder. As destination folder (main batch dialog), set the root folder of your input files, e.g. C:, if all input files are located on C drive.
    Important note: If you want to overwrite original files (if same output filename and format is used), you also have to activate the Advanced Batch dialog option: Overwrite existing files. Be careful with overwriting!
  • Q: Problem: Since yesterday, IrfanView shows all images distorted/stretched! Why?
  • Q: Problem: When I resize/resample an image, the image size doesn't change. Why?
    A: The View menu option like "Fit images to desktop" is activated (or a similar view option), please uncheck and try another display option, e.g. 1:1 to see the original size.
