3x4 cm Photo Resizer

Document photographs come in many different sizes, depending on the country and the type of document. The 30x40mm size is quite popular worldwide, and this size is frequently used for passports, visas, residence permits and ID cards. 

If you’re not sure what size photograph is required for your document, don’t worry. Simply upload your picture to our online app, and our photo resizer will adjust it to the right size for you automatically. Nothing could be easier!

30 x 40 millimeters photo: dimensions

The exact dimensions of the photograph is perhaps the most important requirement for any document photo. So if you’re applying for a visa, a passport, or a driving license, you need to make sure you submit a photo with the correct dimensions. Not all American print shops or photography studios are able to print photos of 30 x 40 mm, so using an online photo maker with automatic framing may be your best solution.

30 x 40 mm photo: equivalents

The equivalents of a 30 x 40 millimeters size photograph are:

• 3x4 centimeters (photo's width is 3 cm and height is 4 cm);
• 1,18 x 1,57 inches (photo's width is 1.18 inches and height is 1.57 inches); these are all the same size. 

30 x 40 mm photo: digital files

When uploading digital photos online, it is crucial to maintain the right proportions; that is, the ratio of 30 millimeters wide to 40mm high must stay the same (3 to 4). As far as size goes, if you’re submitting a JPEG file, it’s probably going to be somewhere between 5 to 10 MB in size.

30 x 40 mm photo: pixels

Digital photos are made up of pixels. The number of pixels will vary depending on the resolution of the photograph. Resolution is expressed in dots per inch (dpi). One digital pixel (px) equals one dot in the printout.

For photographs of 1.18 inches by 1.57 inches, with a resolution of 100 dpi, the number of pixels is: 118 x 157 px (width = 118 pixels, and height 157 pixels). This image would be too pixilated to be acceptable as a passport picture.

For a resolution of 300 dpi: 354 x 472 px (width = 354 px, and height 472 px). This is an image good enough to qualify for passports.

For a resolution of 600 dpi: 708 x 945 px (width = 708 px, and height 945 px). This is the maximum resolution of photo you can submit for any application.

30x40mm photo maker

All pictures uploaded to the editor are automatically verified by AI as either acceptable or unacceptable. If acceptable, the PhotoAiD app will then automatically change the photo size to 30 x 40 mm, crop the headroom, adjust the frame, and make sure that the final photograph meets the official requirements for your passport, visa, ID card or other document. 

30 x 40 mm background remover

If you need to change the background because you couldn’t get the right color in your home, use our background removal tool which replaces your background with the correct one. It takes only a few seconds to get perfect results.

30 x 40 mm photo cropper

Cut and crop the picture for your document quickly and easily with our photo cropper. We automatically check and adjust the size of the face, the height of the eyes and the distance from the top of the head to the top of the photo, cropping it perfectly as required. The photo cropper not only crops and resizes your photograph, but also converts the image into JPG format for you.

30 x 40 mm photo verification

Once the photo is made, we then verify that it meets all specifications including photo quality, facial expression, head position, background color, patterns, lighting, and so on. Photos that don’t meet the official requirements are rejected. Every photo which is validated by our photo creator has a 200% guarantee: if not accepted, we refund double your money back. 

30 x 40 mm photo template 

After final verification, we send you a JPEG photo template to you via email. You can print it in a local photo lab for as little as 35 cents. Or you can choose to have printed photographs delivered to your home.
