Resize an image to 500×500 pixels
To resize an image to 500×500 px, enter 500 × 500 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 0.25 megapixels; as a JPEG, a detailed outdoor photo is about 84.5 KB at the panel's default quality 85 (63.1 KB at quality 75).

What 500×500 means in pixels
500×500 is a square, 500 pixels on each side, 250,000 pixels in total (0.25 megapixels). Its sides reduce to 1:1 (1 as a decimal), so any picture cropped to 1:1 scales to it without distortion.
A 12 MP phone photo has 49 times as many pixels, so reaching 500×500 is a clean reduction with no invented detail. Shown 1:1 it fills 500×500 CSS px on a standard screen and 250×250 CSS px on a 2× (Retina-class) screen; at 72 DPI the same pixels span 6.9×6.9 inches.
Decoded for editing it occupies 977 KB of memory (4 bytes per pixel); uncompressed 24-bit RGB would be 732 KB, which is why the downloadable JPEG, PNG or WebP is far smaller.
Getting 500×500 from a phone, camera or screenshot
Filling 500×500 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 500×500. From the phone photo PixelFit takes the 3024×3024 crop through 1512×1512 and 756×756 before the last step to 500×500, 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% | 0.165× (reduced) | 500×375 |
| 24 MP camera photo (6000×4000, 3:2) | 4000×4000 (left and right cut) | 33.3% | 0.125× (reduced) | 500×333 |
| Full HD screenshot (1920×1080, 16:9) | 1080×1080 (left and right cut) | 43.8% | 0.463× (reduced) | 500×281 |
| Vertical phone video frame (1080×1920, 9:16) | 1080×1080 (top and bottom cut) | 43.8% | 0.463× (reduced) | 281×500 |

Is 500×500 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, 500×500 covers 1.67×1.67 in; at 150 DPI the same pixels stretch to 3.33×3.33 in with half the density.
| Resolution | Print size (inches) | Print size (cm) |
|---|---|---|
| 72 DPI | 6.94×6.94 in | 17.6×17.6 cm |
| 96 DPI | 5.21×5.21 in | 13.2×13.2 cm |

How to resize a picture to 500×500
-
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 500 as the width and 500 as the height in pixels (the panel is already set to 500×500).
-
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 500×375 file instead; Pad with colour puts that on a full 500×500 canvas.
-
Pick the format and download
Choose JPG or WebP; without a KB limit PixelFit saves JPG at quality 85, about 84.5 KB for a detailed outdoor photo. Add a KB limit if the upload has one or the file should be smaller, then download the 500x500 file.

Frequently asked questions
How do I resize an image to 500x500?
Open the image in the PixelFit panel on this page, set 500 × 500 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 0.165×.
What aspect ratio is 500x500?
500x500 has an aspect ratio of 1:1: square, width ÷ height = 1. Sizes with the same ratio include 512×512 PWA icon, 600×600 square and 400×400 square.
Is 500x500 good for print?
At 300 DPI 500x500 prints 1.67×1.67 in (4.2×4.2 cm), smaller than a passport photo, so it is a screen size rather than a print size. At 150 DPI it stretches to 3.33×3.33 in.
How big is a 500x500 JPEG file?
For a detailed outdoor photo about 63.1 KB at quality 75 (47.1 KB at 60, 103 KB at 90, 84.5 KB at the panel's default quality 85); a head-and-shoulders portrait is about 34.5 KB at quality 75, estimated from measured encodes. A flat graphic is smaller, a noisy low-light photo larger.
How does 500x500 look on a high-density screen?
On a 2× screen 500x500 is sharp when shown at 250×250 CSS px; shown larger, the browser enlarges it. A slot of 500×500 CSS px on a 2× screen needs a 1000×1000 file.
