  2. Can Fotosizer be installed silently?

    Use a /S (uppercase) parameter when you run the installer. This will use all the default options and not display any setup windows.

  3. Can Fotosizer be installed to another folder using a command line parameter?

    Use a /D (uppercase) parameter when you run the installer. It must be the last parameter used in the command line and must not contain any quotes, even if the path contains spaces. Only absolute paths are supported.

    For example this will install silently and set the installation folder to C:\Program Files\Fotosizer:
    fsSetup.exe /S /D=C:\Program Files\Fotosizer

    (note: this is a fictitious product key for the example only)

    By default, the filename in the destination settings section is set to "Create copies" with a filename mask of "%F (copy)" you can change this to a custom filename mask by selecting "Custom" from the filename drop-down selection box, then choose the filename mask you wish as below.

    • %H - New height (in pixels)
    • %PW - Percentage width
    • %PH - Percentage height

  14. What happens when I select the "Duplicate source image folders" setting?

    The "Duplicate source image folders" setting tells Fotosizer to re-create the folder structure of your source images in the destination folder.

    Destination Folder: D:\My Documents\My Pictures
    Source Image location: C:\Test pictures\large\boat_hiRes.jpg

    The folder image will be resized and saved to the folder:
    D:\My Document\My Pictures\Test pictures\large

  31. Can you provide an explanation of the resize modes?

    Resize modes

    • Fit: Resizes and fits the picture into the chosen width and height, maintaining the original aspect ratio. The width and height will be adjusted if required to maintain the original ratio.

    • Stretch: Resizes the picture to the chosen width and height, stretching if width and height make it so. This mode does not maintain aspect ratio. This is more of a "free" resize, allowing you to resize to any width and height and not care about maintaining aspect ratio.

    • Side: The Side resize mode allows resizing of one side of the picture only. The other side will be automatically adjusted to maintain the original aspect ratio. This is particularly useful when resizing a mix of portrait and landscape pictures. You can choose to resize the longest side and it will keep the same orientation and resize to you desired size.

    • Pad: This resize mode allows you to freely choose a width and height for your pictures, without requiring aspect ratio to be maintained. The pictures will be resized to fit inside the chosen dimensions, with the remaining space being "padded" with a background colour. You can choose the position inside the boxed area your picture will be positioned.

    • Crop: This resize mode allows you "crop" a section of your picture, at a chosen position inside your picture.
  32. Can I move my Fotosizer settings profiles to another computer?

    Yes, Fotosizer saves your profiles to your User profile AppData folder. If you would like to move these to another computer or to another users profile on the same computer, just copy the file below to the same folder for the user on the other computer.

    1. In Windows Explorer, you can find the Fotosizer profiles file by entering this into the address bar:

    2. The file is named "FSProfiles.dat", copy it to the %USERPROFILE%\AppData\Roaming folder on the other computer.
  33. When downloading a new Fotosizer release, I see a Windows Defender SmartScreen warning. Is it safe to download?

    Yes, the Fotosizer installer is completely safe to download.

    If a file you are about to download is known by SmartScreen to be downloaded by a reasonably large number of people and considered to be safe, it lets you download it without any warnings. If a file has not been downloaded much by others or, a small number of people downloaded it, then it warns that it might not be a safe thing to do.

    When new Fotosizer releases are first available, not many people have yet downloaded that new release, so this is why the warning is displayed. The more people download, the reputation of the Fotosizer release grows, and then after time, you will no longer see the warning.

    To allow the download, simply follow these steps below:

    1. Click the "more info" link on the SmartScreen warning dialog
    2. Click the "Run anyway" button to allow the download

    SmartScreen download warning
    SmartScreen download run anyway

    6. Select Maximize from the pop-up menu. This should show Fotosizer in a maximized state.
    7. You can now resize the Fotosizer window to your desired size. Close Fotosizer, then we open it again. It should now display correctly.
  35. Can I resize and convert my images in HEIC file format with Fotosizer?

    Unfortunately, Fotosizer does not currently support resizing of HEIC images. We do aim to add this feature but do not have a time line for this yet. In the meantime, you may wish to use our recommendation of a 3rd party application to convert the HEIC images to JPEG and then use Fotosizer:

    1. Go to
    2. Click the Download button.
    3. Run the installer and during the setup, choose the "I am installing CopyTrans HEIC for home use" option.
    4. Once installed, go to your folder containing the HEIC files, then select them, right-click on the selection and choose the "Convert to JPEG with CopyTrans" option.
    5. You will see that the images are converted to JPEG and saved to the same folder.
    6. You can then open these converted JPEG images into Fotosizer.
  36. When I try to resize my images, it fails with errors of "A generic error occurred in GDI+", how can I fix this?

    We have had reports of the AVG Anti-virus software and also the Avast Free Anti-virus blocking when saving images with Fotosizer which lead to this error. This can easily be fixed by following the below steps to add Fotosizer to the "Allowed apps" list in AVG Anti-virus:

    1. Open AVG Anti-virus or Avast Free Anti-virus.
    2. Click the Menu.
    3. Click the Settings option.
    4. With the General tab selected, click the Blocked & Allowed apps option.
    5. Under the List of allowed apps section heading, click the ALLOW APP button.
    6. Wait for the list of apps to be displayed, then scroll to Fotosizer in the list of apps.
    7. Click the Add app button next to Fotosizer in the list.
    8. In the Add allowed app popup dialog, select all features that are listed and click the ADD button.
    9. You should now see Fotosizer listed under the list of allowed apps.
    10. Click the Close link at the top of the settings dialog.
    11. Try resizing in Fotosizer again. This time it should all be successful.
  37. When I try to use Webp images in Fotosizer or resize other images to WebP it fails with the error "The type initializer for 'Fotosizer.Imaging.Format.NativeMethods' threw an exception", how can I fix this?

    Fotosizer depends upon a file "libwebp.dll" that is installed into either the x64 or x86 folder inside the Fotosizer installation folder. This file requires the Microsoft file msvcr120.dll from the "Visual C++ Redistributable Package for Visual Studio 2013" to be installed on the computer.

    The error you are seeing suggests that either the file is not in the correct folder or the msvcr120.dll is not installed.

    Checking for the libwebp.dll file:
    1. Please look inside the installation folder for Fotosizer. This is usually C:\Program Files\Fotosizer or C:\Program Files (x86)\Fotosizer.
    2. If your Windows computer is 64 bit, there should be an x64 folder in the Fotosizer installation folder and it should contain the libwebp.dll file.
    3. If your Windows computer is 32 bit, there should be an x86 folder in the Fotosizer installation folder and it should contain the libwebp.dll file.
    4. If you don't find the file, our suggestion is that you try re-installing Fotosizer. You should just be able to re-run the Fotosizer installer without needing to uninstall first, then it will just replace any missing files.

    WebP support in Fotosizer requires the Microsoft file msvcr120.dll from the "Visual C++ Redistributable Package for Visual Studio 2013" to be installed on the computer in the C:\Windows\System32 folder.

    In most cases this will already be installed, but if this is not installed, please follow in steps below:

    1. Download and install the "Visual C++ Redistributable Package for Visual Studio 2013" from the link below:
    2. Click the download link for your language and version of windows, x64 for 64-bit or x86 for 32-bit. Once downloaded, run the installer. When the installer has finished you will be asked to restart your computer.
    3. After restarting, please try again with your WebP images in Fotosizer.
  38. What is the difference between the Text watermark settings "Reduce font size to fit" and "Scale font size proportional to image"?

    The "Reduce font size to fit" setting will reduce the font size to fit the text watermark within the image, but will not increase the font size if the text is smaller than the image.

    The "Scale font size proportional to image" setting will scale the font size to fit the image. For example:

    • If the font size is smaller than the percentage proportion of the image, it will be enlarged to fit.
    • If the font size is larger than the percentage proportion of the image, it will be reduced to fit.
