  • The first thing to know, before you start doing anything else, is what is the photo going to be used for? This will determine the DPI (dots per square inch) that you need. Web is 72, print is a minimum (!) of 300. DPI ( dots per inch ) is a measurement of printer resolution, though it is commonly applied, somewhat inappropriately, to monitors, scanners and even digital cameras. For printers, the DPI specification indicates the number of dots per inch that the printer is capable of achieving to form text or graphics on the printed page. The higher the DPI, the more refined the text or image will appear. To save ink, a low DPI is often used for draft copies or routine paperwork . This setting might be 300 or even 150 DPI. High resolution starts at 600 DPI for standard printers, and can far exceed that for color printers designed for turning out digital photography or other high-resolution images. In the case of monitors, DPI refers to the number of pixels present per inch of display screen. The technically correct term is "PPI" or pixels per inch, but DPI is commonly used instead. A display setting of 1280 x 1024 has 1.3 million DPI, while a setting of 800 x 600 has 480,000, or less than half the resolution of the higher setting. With fewer dots per inch, the picture will not have the clarity that can be achieved with a higher DPI saturation. This is because displays create images by using pixels. Each dot or pixel reflects a certain color and brightness. The greater the DPI, the more detailed the picture can be. Higher DPI also requires more memory and can take longer to 'paint' images, depending on the system's video card, processor and other components. Scanners also operate at different resolutions. Scan time will increase with higher DPI settings, as the scanner must collect and store more data. However, the greater the DPI, or requested resolution, the richer the resulting image. A high DPI setting mimics the original image in a truer fashion than lower DPI settings are capable of doing. If the image is to be enlarged, a high DPI setting is necessary. Otherwise the enlarged picture will look "blocky" or blurry because the software lacks information to fill in the extra space when the image is enlarged. Instead it "blows up" each pixel to "smear" it over a wider area. Technically again, the more correct term in this application is sampled PPI , but DPI is more often used.
  • All artwork design programs allow you to resize an image you are working on, but it's important to understand why simply resizing a low resolution image will not produce a true high resolution image. When you resize and make a low resolution image larger to meet the commercial printing specifications of 300DPI, all you are really doing is stretching the image. The technical term is called either resampling or interpolation. Since high resolution images are based upon the number of pixels an image contains, resizing will not create new pixels, information of your images and will only make each pixel larger by stretching it. The only way to ensure picture perfect high quality printing of your photos and images is to start with a high resolution image obtainable by the methods mentioned below. With this in mind, the high mega pixel camera you have taking the picture, the higher resolution the photos will be. Most cameras that can take photos above 3 mega pixels should be more than adequate to provide you with high resolution images. Keep in mind that you must have your camera set to the highest possible resolution when capturing your images.
  • Upload a photo to Web Resizer and you can not only resize the image to smaller dimensions, but tweak its appearance and image quality. You can round the corners or leave them square, add a border, crop, rotate, sharpen and adjust the image quality to push the image size down even further. If you're unable to decide which image quality setting is best, you can check the "Compare Image Sizes" box and Web Resizer will lay out images in increments of 10 points on the scale for you to compare. You can also do basic adjustments to the contrast, exposure, and tint of the image. It's not a tool for batch conversion or heavy editing but for individual tweaking to optimize a handful of site images or adjust a profile picture to fit within the size and resolution requirements of a site you want to upload it to, it's a handy and free tool.
  • There are probably hundreds of online photo editors! Many have limited functionality, especially when compared to high-end professional products such as Photoshop or Paint Shop Pro. However, there are still quite a few that can get most basic non-professional jobs done.
