Image Resizer to 3.5 x 1.5 cm

It means the resized image has a physical width of 3.5 cm and a height of 1.5 cm. The corresponding pixel dimensions depend on the DPI selected for the output.

At 300 DPI, 3.5 × 1.5 cm is approximately 413 × 177 pixels. This provides a higher pixel density for the same physical dimensions and can be useful when higher-resolution output is required.

At 200 DPI, 3.5 × 1.5 cm is approximately 276 × 118 pixels. The physical size remains 3.5 × 1.5 cm, while the pixel dimensions are lower than at 300 DPI.

Centimeters define the physical dimensions, while DPI determines how many pixels are used for each inch. Therefore, the same 3.5 × 1.5 cm image has different pixel dimensions at different DPI settings.

At 72 DPI, the size is approximately 99 × 43 pixels; at 96 DPI, 132 × 57 pixels; at 200 DPI, 276 × 118 pixels; and at 300 DPI, 413 × 177 pixels. The physical dimensions remain 3.5 × 1.5 cm at each DPI.

The preset provides the required width and height as the starting dimensions, so you do not have to calculate or enter the target size from scratch. You can still customize the dimensions when a different requirement applies.

The dimensions have a 7:3 aspect ratio. Images with a different original ratio may need to be stretched, fitted, or placed against a background to fill the complete target area.

The result depends on the resize type selected. Stretch fills the complete target area but can change the image proportions, while the fit options preserve the original proportions and handle the remaining area with the selected background treatment.

Stretch mode forces the entire image into the exact 3.5 × 1.5 cm dimensions. If the original image has a different aspect ratio, objects or people in the image may appear wider or narrower.

Use a fit-based resize option instead of stretch mode. This preserves the original proportions while fitting the image within the 3.5 × 1.5 cm area.

Both options preserve the original image proportions while filling the target dimensions. Fit & BG Blur uses a blurred background for the unused area, while Fit & BG Color fills that area with a selected background color.

A background allows an image with a different aspect ratio to fit the exact target dimensions without stretching the original content. This is useful when preserving the appearance of the subject is more important than filling the area with the image itself.

A custom background color lets you choose how the unused area around a fitted image appears. This can help the final 3.5 × 1.5 cm image match a document, design, or other visual requirement.

No. When the width and height remain 3.5 × 1.5 cm, those physical dimensions stay the same. Changing DPI changes the corresponding pixel dimensions and the amount of image data used for that physical size.

Choose the DPI specified by the destination, document, or printing requirement. The tool provides 72, 96, 200, and 300 DPI, with higher DPI producing more pixels for the same physical dimensions.

300 DPI produces approximately 413 × 177 pixels for the specified physical size. It can be useful when the output requirement calls for a higher-resolution image or 300 DPI printing.

The image is reduced to the specified physical dimensions, with the resulting pixel dimensions determined by the selected DPI. A large original generally provides more source detail for the resizing process than a very small original.

The image can be resized to the requested dimensions, but increasing its size cannot recreate detail that was not present in the original. For important output, check the resized image for softness or loss of detail.

Locking the aspect ratio keeps the image's original proportions when one dimension changes. If you need the output to be exactly 3.5 × 1.5 cm, the ratio may need to be unlocked when the original image does not already match 7:3.

Lowering the quality can help reduce the final file size when a smaller image file is required. The trade-off is that stronger compression can make fine details less clear, so the output should be checked when image appearance matters.

The tool supports JPG, JPEG, PNG, WebP, and GIF as output formats. The appropriate choice depends on whether you prioritize file size, image quality, transparency, or animation support.

Resizing and re-encoding an image can change its pixel data and compression characteristics. Processing that new file again may therefore produce a different result from resizing the original image, so the original is the better source when creating another version.

At 72 DPI, the size is approximately 43 × 99 pixels; at 96 DPI, 57 × 132 pixels; at 200 DPI, 118 × 276 pixels; and at 300 DPI, 177 × 413 pixels. The width and height are reversed compared with the 3.5 × 1.5 cm orientation.

Both use the same physical dimensions, but their width and height are reversed. 3.5 × 1.5 cm is landscape, while 1.5 × 3.5 cm is portrait.

Select cm as the unit, enter 1.5 cm for width and 3.5 cm for height, then choose the required DPI and resize option. The resulting image follows the selected physical dimensions and resolution.
