Convert an image to 4:3 ratio
4:3 was the dominant shape for television and computer monitors before widescreen took over, and it is still the default photo ratio on many point-and-shoot cameras and phone camera apps. It remains common in classic PowerPoint/Keynote slide templates and several standard print sizes.

How to convert your image to 4:3 ratio
Upload your image using the tool above.
If your source photo is already close to 4:3, the crop will be minimal.
For a wide 16:9 source, pad mode keeps the full image visible and adds neutral bars above and below.

Why do you need to convert to 4:3 ratio?
Many phone cameras still default to 4:3 for photos, and classic presentation templates, projectors, and several print formats were all built around this ratio. If you are mixing images from different sources into a single presentation or print set, converting everything to 4:3 keeps the layout consistent without unexpected white space.
Common pixel sizes for this ratio (4:3)
Where this ratio is used
- Photos taken with compact cameras and many phone camera apps in default mode
- Classic (4:3) PowerPoint and Keynote slide templates
- Some e-commerce marketplace product thumbnails
- Older monitor and projector display content
Crop or pad — which should you use for this ratio?
Cropping to 4:3 works cleanly when the subject already fills the frame from edge to edge — little gets cut that wasn't already tight. When converting a wider 16:9 or square source and the goal is to preserve every part of the original shot, padding is the better route, adding neutral space above, below, or beside the photo instead of trimming it.
How this ratio compares to a similar one
4:3 vs 3:2: 4:3 is slightly taller/more square-ish and matches older cameras, TVs, and classic slide decks; 3:2 is a bit wider and matches modern DSLR/mirrorless sensors. If you're not sure which your source camera used, 3:2 is the more common choice for anything shot in the last 15 years on a dedicated camera.
Frequently asked questions
Why is 4:3 still relevant if widescreen (16:9) is standard now?
Many phone cameras still default to 4:3 for photos (not video), and a lot of older slide decks, projectors, and print templates were built around 4:3 and are still in active use, especially in business and education settings.
Is 4:3 the same as a standard 4×3 inch print?
The ratio matches, but the actual print size 4×3 inches is uncommon; more typical 4:3-ratio prints are sized like 6×4.5 in or 8×6 in.
Will converting a 16:9 photo to 4:3 lose much of the image?
Cropping from 16:9 to 4:3 removes a noticeable amount from the sides since the ratios differ significantly. If the subject fills the frame edge-to-edge, padding instead of cropping preserves more of the original.
Do PowerPoint and Keynote still support 4:3 slides?
Yes, both still let you choose a 4:3 slide size, though the default in recent versions is 16:9. 4:3 is mostly kept for compatibility with older templates and projectors.
Will a 4:3 photo look outdated on modern screens?
Not necessarily — 4:3 is simply a shape, not a quality indicator. It will show with some empty space (pillarboxing) on a widescreen display unless the surrounding design fills that space intentionally.
