Resize Image to 4:3 Aspect Ratio

4:3 is the classic picture shape: the format of older monitors and TVs, of iPads and many tablets, of standard presentation slides, and of the photos produced by most phone and compact camera sensors. Images at 4:3 look natural in these places without bars or awkward cropping.

This resizer outputs 4:3 images at 1024 × 768 pixels. Unlike the other ratio presets it starts with Fit with background, so the whole image is kept and any empty space becomes an even border in white or a colour you choose. Switch to Crop to fill when you prefer a full frame and can accept trimmed edges. Larger 4:3 sizes such as 1600 × 1200 or 2048 × 1536 can be typed in.

How to use the 4:3 Image Resizer

1. Drop your images onto the upload area, click it to choose files, or paste an image with Ctrl+V. This page accepts JPG, PNG, WebP, GIF and BMP files, many at once and up to 80 MB each.
2. Keep 1024 × 768 or type another 4:3 size: 800 × 600, 1600 × 1200 or 2048 × 1536 for Retina tablets.
3. Keep Fit with background and choose a border colour, or switch to Crop to fill and select the part to keep.
4. Check the result with the before/after slider: drag the divider across the preview and read the new dimensions, file size, quality and percentage saved underneath. Any change to the settings re-processes every image automatically.
5. Download a single image, or use Download all (ZIP) for the whole batch. Under More options you can also set a DPI value and a file-name pattern with {name}, {w} and {h}.

Where 4:3 images fit best

• Presentations built on 4:3 slide templates.
• Tablets and e-readers, many of which have 4:3 screens.
• Photo prints and albums based on 4:3 camera images.
• Other ratios: widescreen 16:9 and square 1:1 have their own pages.

Bars or crop?

Fit with background adds bars where the original shape differs from 4:3, which keeps every part of the image and suits documents, artwork and products. Crop to fill gives a cleaner full-frame look but removes the edges, which works well for landscapes and casual photos. Try both on one image with the before/after slider, then apply the better one to the whole batch.

Most phone photos are already 4:3, so resizing them mainly changes the pixel size. Converting 16:9 images to 4:3 with Crop to fill trims the sides; Fit with background keeps everything with bars above and below.
