When the print and paper shapes differ, a print shop "fit" typically fills all of the paper, fitting one dimension to leave no unfilled white space border in the other. The image "shape" (which is width / height, called Aspect Ratio) likely rarely matches the paper "shape", so which always needs attention first. Images have both size and shape properties. But it will not necessarily fit the paper "shape", which requires cropping attention done by you. This scaling will print at a new dpi which will fit the paper size. This can be borderless if so specified in the printer Properties. However, most photo editors will also provide an option to "Scale to fit media" or "Best fit to page", which will scale the image to fit the specified paper size (similar to the labs above). Hopefully, you have already properly scaled the image for your selected paper size. But the dpi number that your digital camera initially stores in the image file, unless you have reset it to your planned value, is otherwise far from meaningful, it is just some arbitrary number, which will print SOME size, but not likely to be your own printing goal.

For example, if an image dimension is 3000 pixels, then specifying that file number as 300 dpi printing resolution will print it to be 3000/300 = 10 inches print size (even if the paper is only 4圆). But it typically will also allow changing that dpi, called scaling (to fit the paper size).

If printing yourself at home, the Print menu in your photo editor normally does use the file's scaled image dpi number (pixels per inch) to size the images on paper (regardless if it matches the paper size at all).

But if the provided image shape does not match the paper shape, the excess image outside the paper edges simply disappears, results may not be what you expected. Or, if too small (insufficient pixels provided), the print quality will be lower, and the lab may refuse worst cases. That's not necessarily a problem, except a far too-large image will be slow to upload. If your image dimensions are too large, the photo shop will first resample it to this smaller requested size.

Planning ahead to avoid surprises by first cropping the image to match that paper shape, and also to provide enough pixels so that the result will be 250 to 300 pixels per inch will be a very good plan. The only concern if is if you gave them enough pixels to print well. If you order 8x10 inches, you will get 8x10 print size. They will ignore your dpi number already in the image file, and will recompute their own necessary "pixels per inch" value, to scale your image to their paper size.

The photo printing shops where we order prints will offer a paper size, and will fill that paper with your image.

There are two situations when printing images, depending on if using print shops or home printing. The dpi calculator is below, but first, some background concerns. But here, we're speaking about printing resolution of image pixels, which ink jets also have to do. Ink jet printers do have their own other thing about ink drops per inch (but which is about the quality of dithering colors (to color each pixel), not about image resolution). Some do call it ppi now, same thing, pixels per inch, which is what it is.

In the bottom of page you can see examples with using our free jpg resizer tool.FWIW, I'm old school, and I learned the term for printing resolution as "dpi", so that's second nature to me, dpi has simply always been the name of it.

Online jpg resize tool will return jpg image, it size is linked with quality and smoothing. The compression method is usually lossy, that is why some original image information is lost and cannot be restored after conversation.

JPEG typically achieves 10:1 compression with little perceptible loss in image quality. The degree of compression can be adjusted, with maximum image quality file will have maximum size, with minimum - minimum size. JPEG is a commonly used method of compression for photographic images, or hight quality painted images, but it not allow transparent pixels. In other case (simple jpg resizing) - you will get image that consist of "big pixels". If you using jpeg resizing tool for make image much bigger than native size - it will be usefull to use "Smoothly interpolation", it's will be looking like some blur, It can be size in pixels or in percents (use dropdown menu for change), limit of future filesize is 20MegaPixels.

How to use this tool?įirst of all - you must specify jpeg file that will be used by online jpg resize tool, the second obligatory step - choose width and height of furute image, It's a jpeg resizing web accessible for everyone.
