Resize an image to 1500×1500 pixels
To resize an image to 1500×1500 px, enter 1500 × 1500 px and pick crop to fill so the 1:1 frame is not stretched: a 4:3 phone photo loses 25% of its area (a centred 3024×3024 crop). The result has 2.25 megapixels; as a JPEG, a detailed outdoor photo is about 745 KB at the panel's default quality 85 (566 KB at quality 75).

What 1500×1500 means in pixels
1500×1500 is a square, 1500 pixels on each side, 2,250,000 pixels in total (2.25 megapixels). Its sides reduce to 1:1 (1 as a decimal), so any picture cropped to 1:1 scales to it without distortion.
That is 18.5% of a 12 MP phone frame; after the crop to fill the phone picture is reduced by 0.496×, so fine detail such as hair and text survives. Shown 1:1 it fills 1500×1500 CSS px on a standard screen and 750×750 CSS px on a 2× (Retina-class) screen; at 72 DPI the same pixels span 20.8×20.8 inches.
Decoded for editing it occupies 8.58 MB of memory (4 bytes per pixel); uncompressed 24-bit RGB would be 6.44 MB, which is why the downloadable JPEG, PNG or WebP is far smaller.
Getting 1500×1500 from a phone, camera or screenshot
Filling 1500×1500 from a 12 MP phone photo (4032×3024, 4:3) loses the least (25%); a vertical phone video frame (1080×1920, 9:16) loses the most (43.8%). "Fit inside" keeps the whole picture instead and the file comes out at the size in the last column; "Pad with colour" adds bars to reach the full 1500×1500. From the phone photo PixelFit takes the 3024×3024 crop through 1512×1512 before the last step to 1500×1500, so each pass blends neighbouring pixels instead of skipping them.
| Starting image | Crop to fill keeps | Area lost | Scale | Fit inside gives |
|---|---|---|---|---|
| 12 MP phone photo (4032×3024, 4:3) | 3024×3024 (left and right cut) | 25% | 0.496× (reduced) | 1500×1125 |
| 24 MP camera photo (6000×4000, 3:2) | 4000×4000 (left and right cut) | 33.3% | 0.375× (reduced) | 1500×1000 |
| Full HD screenshot (1920×1080, 16:9) | 1080×1080 (left and right cut) | 43.8% | 1.389× (enlarged) | 1500×844 |
| Vertical phone video frame (1080×1920, 9:16) | 1080×1080 (top and bottom cut) | 43.8% | 1.389× (enlarged) | 844×1500 |
When 1500×1500 means enlarging
After the crop to fill, the kept region has to be enlarged 1.389× from a Full HD screenshot and 1.389× from a vertical phone video frame. Enlarging adds pixels but no detail, so start from the largest original you have, or choose a smaller target if the destination allows it: 1200×1500 portrait or A6 (105×148 mm) would need less stretching.
How many KB is a 1500×1500 image?
Estimated from encodes of real sample images measured with sharp 0.35.5 / libvips 8.18.7 on 31 October 2026, interpolated to 2,250,000 pixels. The outdoor photo at 1500×1500 is about 566 KB at quality 75 and a scanned page about 258 KB; your file will differ with detail and noise.

Will a 1500×1500 photo fit an upload limit?
The highest JPEG or WebP quality that stays under each limit at exactly 1500×1500 px, from the same measurements. Set the KB limit next to the pixel size and PixelFit runs this search on your own photo.
| Limit | Portrait, JPEG | Outdoor photo, JPEG | Outdoor photo, WebP |
|---|---|---|---|
| Under 200 KB | up to quality 75 | does not fit even at quality 30 | does not fit even at quality 30 |
| Under 500 KB | up to quality 93 | up to quality 67 | up to quality 73 |
| Under 1 MB | fits at quality 95 | up to quality 91 | up to quality 93 |
Is 1500×1500 good for print?
Pixels carry no physical size until you pick a DPI. At 300 DPI, the resolution PixelFit uses for its print and ID photo sizes, 1500×1500 covers 5×5 in; at 150 DPI the same pixels stretch to 10×10 in with half the density.
| Resolution | Print size (inches) | Print size (cm) |
|---|---|---|
| 72 DPI | 20.83×20.83 in | 52.9×52.9 cm |
| 96 DPI | 15.63×15.63 in | 39.7×39.7 cm |
| 150 DPI | 10×10 in | 25.4×25.4 cm |
| 200 DPI | 7.5×7.5 in | 19.1×19.1 cm |
| 300 DPI | 5×5 in | 12.7×12.7 cm |
| 600 DPI | 2.5×2.5 in | 6.4×6.4 cm |

How to resize a picture to 1500×1500
-
Add the picture
Drop, paste or pick the photo in the PixelFit panel at the top of this page; it is decoded in your browser and never uploaded.
-
Set the size
Enter 1500 as the width and 1500 as the height in pixels (the panel is already set to 1500×1500).
-
Choose how it fits
Choose crop to fill to keep the 1:1 frame without stretching (a phone photo loses 25%, left and right cut). Fit inside keeps the whole picture as a 1500×1125 file instead; Pad with colour puts that on a full 1500×1500 canvas.
-
Pick the format and download
Choose JPG or WebP; without a KB limit PixelFit saves JPG at quality 85, about 745 KB for a detailed outdoor photo. Add a KB limit if the upload has one or the file should be smaller, then download the 1500x1500 file.

Frequently asked questions
How do I resize an image to 1500x1500?
Open the image in the PixelFit panel on this page, set 1500 × 1500 px, choose crop to fill so nothing is stretched and download. From a 12 MP phone photo that crops 25% (left and right cut) and scales the rest by 0.496×.
What aspect ratio is 1500x1500?
1500x1500 has an aspect ratio of 1:1: square, width ÷ height = 1. Sizes with the same ratio include 1600×1600 square, 1200×1200 square and 2000×2000 square.
Is 1500x1500 good for print?
At 300 DPI 1500x1500 prints 5×5 in (12.7×12.7 cm), enough for a print of that size at full density. At 150 DPI it stretches to 10×10 in.
How big is a 1500x1500 JPEG file?
For a detailed outdoor photo about 566 KB at quality 75 (428 KB at 60, 905 KB at 90, 745 KB at the panel's default quality 85); a head-and-shoulders portrait is about 194 KB at quality 75, estimated from measured encodes. A flat graphic is smaller, a noisy low-light photo larger.
How does 1500x1500 look on a high-density screen?
On a 2× screen 1500x1500 is sharp when shown at 750×750 CSS px; shown larger, the browser enlarges it. A slot of 1500×1500 CSS px on a 2× screen needs a 3000×3000 file.
