Resize an image to 630×810 pixels
To resize an image to 630×810 px, enter 630 × 810 px and pick crop to fill so the 7:9 frame is not stretched: a 4:3 phone photo loses 41.7% of its area (a centred 2352×3024 crop). The result has 0.51 megapixels; as a JPEG, a head-and-shoulders portrait is about 79.3 KB at the panel's default quality 85 (59.3 KB at quality 75).

What 630×810 means in pixels
630×810 is a portrait frame, 1.29 times as tall as it is wide, 510,300 pixels in total (0.51 megapixels). Its sides reduce to 7:9 (0.7778 as a decimal), so any picture cropped to 7:9 scales to it without distortion.
A 12 MP phone photo has 24 times as many pixels, so reaching 630×810 is a clean reduction with no invented detail. Shown 1:1 it fills 630×810 CSS px on a standard screen and 315×405 CSS px on a 2× (Retina-class) screen; at 72 DPI the same pixels span 8.8×11.3 inches.
Decoded for editing it occupies 1.95 MB of memory (4 bytes per pixel); uncompressed 24-bit RGB would be 1.46 MB, which is why the downloadable JPEG, PNG or WebP is far smaller.

Getting 630×810 from a phone, camera or screenshot
Filling 630×810 from a vertical phone video frame (1080×1920, 9:16) loses the least (27.7%); a Full HD screenshot (1920×1080, 16:9) loses the most (56.3%). "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 630×810. From the phone photo PixelFit takes the 2352×3024 crop through 1176×1512 before the last step to 630×810, 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) | 2352×3024 (left and right cut) | 41.7% | 0.268× (reduced) | 630×473 |
| 24 MP camera photo (6000×4000, 3:2) | 3111×4000 (left and right cut) | 48.2% | 0.203× (reduced) | 630×420 |
| Full HD screenshot (1920×1080, 16:9) | 840×1080 (left and right cut) | 56.3% | 0.75× (reduced) | 630×354 |
| Vertical phone video frame (1080×1920, 9:16) | 1080×1389 (top and bottom cut) | 27.7% | 0.583× (reduced) | 456×810 |

How to resize a picture to 630×810
-
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 630 as the width and 810 as the height in pixels (the panel is already set to 630×810).
-
Choose how it fits
Choose crop to fill to keep the 7:9 frame without stretching (a phone photo loses 41.7%, left and right cut). Fit inside keeps the whole picture as a 630×473 file instead; Pad with colour puts that on a full 630×810 canvas.
-
Pick the format and download
Choose JPG or WebP; without a KB limit PixelFit saves JPG at quality 85, about 79.3 KB for a head-and-shoulders portrait. Add a KB limit if the upload has one or the file should be smaller, then download the 630x810 file.
