How to Use 3x4 Resize Tool
- Upload single or multiple images (JPG, PNG, WebP, GIF). All processing happens in your browser.
- Set target dimensions – default is 1200x1600px (perfect 3:4). You can adjust width or height; the other will automatically maintain 3:4 ratio (dynamic ratio lock).
- Choose crop mode: "Cover" centers and crops to fill the 3x4 box, ideal for portraits. "Contain" fits whole image inside with possible transparent/white letterbox.
- Pick output format & quality – JPEG for small file sizes, PNG for transparency, WebP for modern compression.
- Click "RESIZE TO 3x4 ASPECT RATIO" – each image gets processed, downloaded automatically. Batch mode lets you resize dozens at once.
- All resized images keep metadata stripped for privacy; no server involved.
Why 3x4? It’s a classic portrait format used for ID cards, Instagram portrait posts, thumbnails, and print photos (4x6 inch is essentially 2:3, but 3:4 fits many frame types). Our algorithm guarantees pixel-perfect dimensions without distorting your original subject.
