Processing of JPEG photos online.

Resizing of image in inches or centimeters for printing on paper, with considering DPI online

Specify the image on your computer or phone, enter the size you want in inches, millimeters or centimeters, click OK button at the bottom of the page, wait a few seconds and download the finished result. Other settings are already set by default. On this site you can still change the size in: pixels, megapixels, percentages, megabytes, enlarge small picture, and also preliminary crop or rotate image with considering rotation angle in Exif metadata.

Size of the photo will be changed to the specified size in inches (millimeters, centimeters) according to the specified size in DPI and to the standards of paper printing. Dimensions in inches, mm and cm can be specified accurate to thousandths, например, for example, instead of the 6x4 format can be set 6,121x4,028 inches.

Table with standard US photo print sizes: (other European standard sizes in "cm" you can see here)

Standard Letter (similar to A4) paper sheet size is 8,5x11 inches or 2550x3300 pixels at 300 dpi, which is commonly used in the United States, Canada, Mexico, Chile and the Dominican Republic. Other paper sizes for those countries you can see on Wikipedia page (North American paper sizes).

Standard size of A4 paper sheet is 210x297 mm or 2480x3508 pixels at 300 dpi. Other European formats of paper sheets can be seen in table on Wikipedia page (ISO paper sizes in portrait view).

If you want to change the photo size without regard to DPI, that is, only observing the proportions of the specified format, then you need to set the parameter "Size in DPI" to "0" in the settings of this page.

The original image does not change in any way. You will be given other processed image.

1) Specify image in BMP, GIF, JPEG, PNG, TIFF format:

2) Enter the desired photo format in inches, millimeters or centimeters

Photo format: X in
(By default, is set photo format 6x4, which is suitable for landscape (horizontal) photo, for a portrait (vertical) photograph, these values need to be inverted, that is you need to specify a 4x6 format, as shown in the table of standard print sizes)
Size in DPI: (0 = "do not consider DPI, to make a proportions based on the specified photo format")
(Size of the original jpg-image in DPI can be found here by reading metadata, see there X and Y Resolution)
Type of resizing exactly to the specified photo format:
Keep aspect ratio and crop excess edges
Stretching or narrowing, without cropping
Add: stripes on the edges of image
Attach to: part of image
3) Additional settings

Interpolation: (algorithm for allocation of pixels)
4) Output image format

JPEG with quality (from 1 to 100)
PNG-24 (without compression, transparent background will be replaced by white color)
Copy EXIF and other metadata? Yes No

  Processing usually lasts for 0.5-30 seconds.
