Make a 3x4 photo from a picture already on your phone or computer. This page opens with the 3 × 4 cm size selected: add a photo, the face is found and placed at the right height, and the background turns white. Download the single photo at 354 × 472 pixels, or a 10 × 15 cm sheet holding 8 copies for printing. All of it runs in your browser, so the picture is never uploaded.
Country / region is set to General and Size to 3 × 4 cm. The photo is saved at 354 × 472 pixels, which prints at exactly 3 × 4 cm at 300 dpi.
The AI finds the face and crops so the head is centred and, by default, fills about 68% of the height. A slight head tilt is straightened. Drag or zoom to adjust; two dashed guides show where the crown and chin should sit.
Change colour fills the background with white, or with off-white, light grey, light blue, cream or any colour you pick. Keep original leaves the background the camera recorded.
Under Output, choose Print sheet. The 10 × 15 cm paper is preselected and holds 8 copies with cut lines; 4 × 6 in also holds 8, and A4 holds 36.
3x4 is the everyday ID photo size in Brazil. If a consulate form, school or employer there asks for a "foto 3x4", this is the size it means.
Many card printers and enrolment forms take a small upright photo. A 3 × 4 cm print fits the usual photo box on a paper form.
Upload portals that ask for a portrait in 3:4 proportion accept the single JPG from this page. If the form caps the size in KB, fill in Max file size (KB).
Use a front-facing photo with even light on the face: JPG, PNG, WebP, HEIC, AVIF, TIFF, BMP, or TGA, up to 100MB. iPhone HEIC photos work directly.
The result appears next to the editor. Drag or zoom to show more or less shoulder, and choose a colour under Background. Size check tells you whether the face is centred and level.
Click Download for the 354 × 472 pixel photo. For prints, switch Output to Print sheet and download the 10 × 15 cm sheet of 8.
A 3x4 photo is 3 cm wide and 4 cm tall (30 × 40 mm), always upright. Its 3:4 proportion matches a phone picture held vertically, so cropping removes very little.
The pixel size depends on print resolution. At 300 dpi, the usual photo-lab setting, 3 × 4 cm comes to 354 × 472 pixels, and that is the size this page saves.
Several Brazilian documents now take the picture at the counter. The Minas Gerais national ID card page says the photo is taken on site and a 3x4 is only needed for a baby in arms. The work card captures the photo in its system too; Labour Ministry Ordinance 1/2025 asks for "uma fotografia 3 cm x 4 cm recente" only where that system is missing.
Others still list a printed photo. Espírito Santo's first driving licence checklist asks for one recent colour 3x4 with a light background, and the Santa Catarina identification institute wants two identical 3x4 prints on white, unretouched. Rules differ from state to state, so read the issuing office's page before printing.
When a rule says white background, use Change colour with White: the AI cuts out the person and the backdrop becomes pure white. A "light background" rule also allows off-white or light grey.
If the rule asks for an unretouched photo, as Santa Catarina's does, pick Keep original. Size and framing still change, but the background stays as photographed, so shoot against a plain, pale wall.
The sheet is saved at 10 × 15 cm and 300 dpi, the standard photo size at labs and print kiosks. Ask for actual-size printing, not fit to page, so each copy measures 3 × 4 cm. The thin grey lines are there to guide scissors or a craft knife.
3 × 4 cm: 3 cm wide by 4 cm tall (30 × 40 mm). This page saves it at 354 × 472 pixels, which is 3 × 4 cm printed at 300 dpi.
