Irfanview is a free graphics viewer and editor. You can download it here:
The hardest part is deciding how to get your picture into Irfanview – and that’s pure simplicity itself!!!
This ‘How to’ is written so that those with the minimum of knowledge will be able to resize images using Irfanview. Unless I’ve mentioned them specifically, ignore all boxes and buttons that may or may not be highlighted or ticked. Irfanview defaults many settings to make the whole process as simple as possible.
There is also an animation that you can watch here.
Direct from a gallery on your hard drive – find the picture in your gallery. Right click on the thumbnail or file, scroll down to’ Open with’, and click on Irfanview. (see pic below)
From a gallery on your hard drive via Irfanview – Open Irfanview. Click on file, then ‘open’. Find the thumbnail or file, and ‘double-click’ on it or click once and then click the ‘open’ button.(see pics below)
From a ‘Screenshot’ that you have just placed on your clipboard – Open Irfanview. Click on ‘Edit’ and then ‘Paste’. (see pic below)
Click ‘Image’ and then ‘Resize/Resample’ (see pic below)
The new frame that appears has two ways of resizing. The box circled in green on the left-hand side allows you to custom resize the image to the exact size you want. You only need to type in the width, as the height will adjust automatically (ensure that the ‘preserve aspect ratio’ box is ticked – it should always default to ticked anyway).
The buttons circled in red on the right-hand side are the more common sizes used by most message boards (and PC wallpapers!). Choose whichever size you want and click ‘OK’. (see pic below)
You may notice that the image has blurred slightly, so we next click on ‘image’ and then ‘Sharpen’. (see pic below)
All that’s left now is to save it. So click on ‘file’ and then ‘Save as’. (see pic below)
Choose the name you want to save it as, and where you want to save it to. Also check that ‘Save as type’ (circled in green) says ‘JPG – JPEG Files’. If this needs changing, you can select it from the ‘drop down’ menu.
On the right hand side you will have a box that is about JPEG/GIF Save Options. The slider bar at the top determines how much to compress the file (how large the file will be in kb). The more you compress JPEGS the worse the quality becomes. The figure above the slider is NOT your final file size, but a % of the ‘quality’ based on the original. You can set this to 75 and hardly notice any loss of quality. If you have it at 100 – you’ll get good quality but a massive file size. Click ‘Save’ and that’s it!!! (see pic below).
