Prepare photos for 4x6 printing with the correct crop, ratio, and pixel dimensions.
JPG, PNG, or WebP — processed locally, no upload
Turn any photo into a print-ready 4x6 image. This 4x6 photo resize tool keeps the correct 2:3 ratio so your picture is never stretched.
Switch between Portrait 4x6 and Landscape 6x4 with one click. Both keep the same 2:3 or 3:2 print ratio your lab expects.
Set the 4x6 image size by choosing a print resolution. At 300 PPI the 4x6 in pixels output is 1200 × 1800; at 150 PPI it is 600 × 900.
Crop photo to 4x6 with Fill mode to fill the frame, or use Fit mode with a background color to keep the whole picture. This 4x6 photo crop preview shows exactly what gets trimmed.
Export your 4x6 print size image as a high-quality JPG. Everything runs locally in your browser — no upload, no account.
The 4x6 photo size is 4 inches by 6 inches, which gives a 2:3 aspect ratio (or 3:2 in landscape). In metric units the same 4x6 image size is 10.16 × 15.24 cm, or 101.6 × 152.4 mm. It is the most common rectangle used for photo prints and frames.
Because the ratio is fixed, any picture you send to print should match it — either by resizing to the exact dimensions or by cropping to the 2:3 frame.
The 4x6 photo dimensions are 4 × 6 inches (10.16 × 15.24 cm). When people ask 4x6 in pixels, the answer depends on print resolution, because pixels equal inches multiplied by PPI (pixels per inch). A higher PPI means more pixels and potentially sharper prints, up to the limit of your source photo.
The same 4x6 photo size produces different pixel dimensions depending on the PPI you choose:
| PPI | Portrait (4x6) | Landscape (6x4) | Use |
|---|---|---|---|
| 300 | 1200 × 1800 px | 1800 × 1200 px | High quality print |
| 240 | 960 × 1440 px | 1440 × 960 px | Good quality print |
| 150 | 600 × 900 px | 900 × 600 px | Basic print |
| 96 | 384 × 576 px | 576 × 384 px | Screen preview |
Note: PPI does not add detail on its own. Final sharpness also depends on your source resolution and the print device.
To get a clean result, follow these steps before sending the file to a lab:
Our 4x6 photo resize tool does all of this in your browser — no upload required.
Even when you send a file with the right 4x6 photo size, a lab can still trim a sliver off the edges. Two things cause it.
1. The ratio is close but not exact. Lab printers output to a full sheet of paper with no white border. If your file is only near 2:3 — say 1201×1800 px instead of 1200×1800 px — the machine scales it to fill the sheet and shaves off whatever falls outside. Export the exact pixel dimensions for your chosen PPI rather than an approximation.
2. Bleed and safe area. Photo printers cut the sheet after printing, and that cut is not perfectly precise. Most labs keep a safe margin of roughly 1/8 inch — about 40 px at 300 PPI — around the sheet. Anything important closer to the edge than that can lose a few pixels, which is invisible in a landscape but obvious when it clips a face or a line of text.
How to check before you send the file: look at the masked area in the crop preview above. If a head, a hand, or text sits within about 40 px of the frame edge, either reposition the crop or switch to Fit mode so the whole picture is kept. Portrait photos of people benefit most from this check, because a 4x6 portrait frame sits close to the subject on both sides.
The 4x6 print size is the most common photo print, but you may also need other standard sizes for frames and albums:
Each keeps the same workflow: pick the size, crop to the right ratio, and export a print-ready file.
Drag and drop a photo or browse your device. Batch upload of several images is supported.
Choose portrait or landscape, pick a PPI (300 for high quality), and select Fill or Fit cropping.
Check the crop preview, then download your print-ready 4x6 JPG individually or as a batch.
