Free 45x38 mm Image Converter

At 300 DPI, the target is approximately 531x449 pixels; at 200 DPI, about 354x299 pixels; and at 150 DPI, about 266x224 pixels. The slight rounding comes from converting millimeters to inches. Start with the sharpest original because enlarging a small file does not recreate real detail. After resizing, inspect fine edges and any text at 100% zoom. Print at actual size, disable automatic page fitting, and measure a proof to confirm 45 mm of width and 38 mm of height.

When the values mean width by height, 45x38 mm is landscape because the width is greater than the height. Its aspect ratio is 45:38, or about 1.18:1, so it is only moderately wider than a square. If your requirement lists 38x45 mm instead, that is the rotated portrait version and should not be treated as interchangeable. Confirm the order used by the destination, especially for forms that label dimensions as height by width, and check the preview before printing or uploading.

Pairs, small products, building fronts, vehicles, desk setups, and close landscape scenes can use the extra horizontal space without becoming panoramic. A single headshot can also work when both shoulders or some environmental context are intentionally included. Avoid large groups and dense scenery because faces and fine details become too small at the final size. Preview the image near its real print dimensions, keep the subject away from the outer edge, and choose a larger format if recognition depends on tiny features.

Only when the issuing organization explicitly specifies 45 mm wide by 38 mm high. Most official identity-photo rules use portrait dimensions and may also control head height, eye position, background, expression, and recency. Do not rotate or substitute this landscape preset merely because the numbers resemble another required size. Read the current instruction in its stated width-height order and use any provided crop template. This tool sets dimensions and output settings but does not certify an image for an official application.

It can fill a custom card insert, small inventory thumbnail, product sample sheet, membership record, contact sheet, miniature album slot, or a business layout that reserves a compact horizontal area. The dimensions are not a universal commercial standard, so measure the actual opening or template first. For screen-only use, follow pixel requirements rather than relying on millimeters. Keep labels and detailed text outside the image when possible, because a physically small picture is better used to show one clear visual subject.

Lock the aspect ratio and position a 45:38 crop over the part of the source you want to keep. A vertical image will lose substantial space above and below, so protect faces, hands, and important objects before committing. A square source will lose a smaller strip from the top and bottom. If nothing can be removed, add side margins rather than forcing the image to become wider. Compare circles, faces, and product proportions with the original, and restart from the source file if an earlier export has already been distorted.

Place exact-size frames in rows and leave consistent cutting gaps plus the printer’s non-printable outer margin. The number that fits depends on paper orientation, printer limits, and the cutting method, so do not rely on one universal count. In the print dialog, choose 100% or actual size and turn off fit, fill, and automatic borderless enlargement. Make a proof on plain paper, measure images near the center and outer rows, and only use the final paper when every sample remains 45x38 mm.

High-quality JPEG is practical for photographs and widely supported by print services. PNG is preferable for logos, flat graphics, or text that needs clean edges, although its files are often larger; WebP should be used only if the destination accepts it. Check extension, color profile, transparency behavior, and byte limits before export. Keep a master copy and create the delivery file once, because repeatedly saving a JPEG can introduce visible blocks and halos around small subjects and lettering.
