4:3 Photo Crop

The 4:3 Photo Crop is a free tool that converts images to a landscape four-to-three aspect ratio, four units wide for every three units tall. It offers two modes. Center Crop (Fill) keeps the largest 4:3 area in the middle of your photo and trims the rest. Fit (Add Borders) keeps the whole photo and pads it out to 4:3 with a background color you choose. You can process several images in one go, and each is saved as a JPEG at the quality you set.

Photographers typically choose the 4:3 aspect ratio when preparing images for print sizes, digital displays or platforms that favor a slightly squarer frame than the traditional 3:2 ratio. It is effective for portraits, architecture and landscapes where you want more height relative to width without losing horizontal context. Print sizes such as 6x8, 9x12, 12x16 and 18x24 inches are exact 4:3 shapes, and 4:3 suits tablet and presentation screens, which makes it a practical choice for clients who plan to print or display your work.

Click the file area or drag one or more photos onto it. Your files appear in a list with their sizes, and the settings open. Choose Center Crop (Fill) or Fit (Add Borders), and in Fit mode pick a background color. Set the quality slider, which runs from 1 to 100 and starts at 92. Click Apply 4:3 Crop, and each image is processed in turn and downloaded as a JPEG named with 4_3_Crop_ in front of its original name. Clear All empties the list.

The 3:2 aspect ratio is the native format for most full-frame and APS-C DSLR and mirrorless cameras, offering a wider, more cinematic look. In contrast, the 4:3 ratio is slightly more square. When you convert a 3:2 image to 4:3 in Center Crop mode, the tool trims equal strips from the left and right edges. The 4:3 format is native to Micro Four Thirds cameras and most smartphones. Choosing between them usually depends on the final output; 3:2 is great for expansive landscapes, while 4:3 often provides a tighter, more focused composition for portraits and product photography.

Whenever you crop an image, you remove pixels from the original, which reduces the total resolution of the new file. In Center Crop mode the tool always keeps the largest 4:3 area that fits, at the photo's own pixel density, so it removes only what the ratio change requires. A 6000 by 4000 pixel 3:2 file, for example, becomes 5333 by 4000 pixels. If the result still looks soft, the source was probably small or heavily compressed, so start from a full-size export, and set the quality slider high to keep compression artifacts down.

Medium format film cameras historically used formats like 6x4.5, which works out to a 4:3 ratio and gives a balanced frame that suits editorial and portrait work. Many digital medium format sensors, Micro Four Thirds cameras and smartphone sensors kept this squarer shape, partly because it makes efficient use of the round image circle a lens projects. For photographers, this means files from those cameras need no cropping for 4:3 output, while 3:2 files from full-frame and APS-C cameras lose a little width when converted.

No. This tool always produces a landscape 4:3 image, wider than it is tall, and it has no orientation switch or crop handles. A vertical photo run through Center Crop mode keeps its full width and loses height from the top and bottom, while Fit mode places it in the middle of a wide 4:3 canvas with borders at the sides. If you need a vertical 3:4 result, crop it in your editor, or rotate the photo, crop it here and rotate it back.

First check the file type. The tool accepts JPG, PNG and WebP, along with other image formats your browser can display; anything else is skipped and never appears in the list. Proprietary RAW files such as CR2, NEF or ARW need to be exported to JPEG or PNG in your editor first. Very large images take longer to process because the work happens on your own device, so wait for the status to change to Done. If nothing happens, refresh the page and add the file again.

The tool saves a new JPEG of every image, so some compression always applies, set by the quality slider: 92 is the default, and values toward 100 give larger files with less compression. Your original files are not changed. The new JPEGs do not carry over embedded color profiles or camera metadata, and browsers display untagged images as sRGB, so export Adobe RGB or ProPhoto RGB images to sRGB before cropping them here. That keeps colors consistent on the web and with most print labs.

Composing your shot in-camera is generally the best practice, as it lets you use the full resolution of your sensor and plan lighting and depth of field for the final frame. Many Micro Four Thirds and medium format cameras shoot 4:3 natively, while full-frame cameras can often record a 4:3 crop mode. Shooting a little wider and converting afterward gives you a safety margin, and this tool lets you convert a whole set of images to 4:3 at once, either trimmed or padded with borders, while your originals stay untouched.
