Resize an image to 420×525 pixels
To resize an image to 420×525 px, enter 420 × 525 px and pick crop to fill so the 4:5 frame is not stretched: a 4:3 phone photo loses 40% of its area (a centred 2419×3024 crop). The result has 0.22 megapixels; as a JPEG, a head-and-shoulders portrait is about 41.4 KB at the panel's default quality 85 (31.4 KB at quality 75).

What 420×525 means in pixels
420×525 is a portrait frame, 1.25 times as tall as it is wide, 220,500 pixels in total (0.22 megapixels). Its sides reduce to 4:5 (0.8 as a decimal), so any picture cropped to 4:5 scales to it without distortion.
A 12 MP phone photo has 55 times as many pixels, so reaching 420×525 is a clean reduction with no invented detail. Shown 1:1 it fills 420×525 CSS px on a standard screen and 210×263 CSS px on a 2× (Retina-class) screen; at 72 DPI the same pixels span 5.8×7.3 inches.
Decoded for editing it occupies 861 KB of memory (4 bytes per pixel); uncompressed 24-bit RGB would be 646 KB, which is why the downloadable JPEG, PNG or WebP is far smaller.

Each line comes from the official notice listed under Sources, checked October 2026. Rules change: verify with the notice before you submit.

Getting 420×525 from a phone, camera or screenshot
Filling 420×525 from a vertical phone video frame (1080×1920, 9:16) loses the least (29.7%); a Full HD screenshot (1920×1080, 16:9) loses the most (55%). "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 420×525. From the phone photo PixelFit takes the 2419×3024 crop through 1209×1512 and 604×756 before the last step to 420×525, 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) | 2419×3024 (left and right cut) | 40% | 0.174× (reduced) | 420×315 |
| 24 MP camera photo (6000×4000, 3:2) | 3200×4000 (left and right cut) | 46.7% | 0.131× (reduced) | 420×280 |
| Full HD screenshot (1920×1080, 16:9) | 864×1080 (left and right cut) | 55% | 0.486× (reduced) | 420×236 |
| Vertical phone video frame (1080×1920, 9:16) | 1080×1350 (top and bottom cut) | 29.7% | 0.389× (reduced) | 295×525 |

Will a 420×525 photo fit an upload limit?
The highest JPEG or WebP quality that stays under each limit at exactly 420×525 px, from the same measurements. Set the KB limit next to the pixel size and PixelFit runs this search on your own photo. A portrait at 420×525 is above the 10 KB minimum in the notice above at every measured quality, and it stays under the 20 KB maximum up to quality 42.
| Limit | Portrait, JPEG | Outdoor photo, JPEG | Outdoor photo, WebP |
|---|---|---|---|
| Under 10 KB | does not fit even at quality 30 | does not fit even at quality 30 | does not fit even at quality 30 |
| Under 20 KB | up to quality 42 | does not fit even at quality 30 | does not fit even at quality 30 |
| Under 30 KB | up to quality 71 | up to quality 37 | up to quality 35 |
| Under 50 KB | up to quality 88 | up to quality 68 | up to quality 74 |

How to resize a picture to 420×525
-
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 420 as the width and 525 as the height in pixels (the panel is already set to 420×525).
-
Choose how it fits
Choose crop to fill to keep the 4:5 frame without stretching (a phone photo loses 40%, left and right cut). Fit inside keeps the whole picture as a 420×315 file instead; Pad with colour puts that on a full 420×525 canvas.
-
Pick the format and download
Choose JPG or WebP; without a KB limit PixelFit saves JPG at quality 85, about 41.4 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 420x525 file.

Frequently asked questions
How do I resize an image to 420x525?
Open the image in the PixelFit panel on this page, set 420 × 525 px, choose crop to fill so nothing is stretched and download. From a 12 MP phone photo that crops 40% (left and right cut) and scales the rest by 0.174×.
What aspect ratio is 420x525?
420x525 has an aspect ratio of 4:5: portrait, width ÷ height = 0.8. Sizes with the same ratio include 600×750 px digital passport photo, 1080×1350 portrait and 1200×1500 portrait.
Is 420x525 good for print?
At 300 DPI 420x525 prints 1.4×1.75 in (3.6×4.4 cm), smaller than a passport photo, so it is a screen size rather than a print size. At 150 DPI it stretches to 2.8×3.5 in.
How big is a 420x525 JPEG file?
For a head-and-shoulders portrait about 31.4 KB at quality 75 (24.4 KB at 60, 51.3 KB at 90, 41.4 KB at the panel's default quality 85); a detailed outdoor photo is about 55.5 KB at quality 75, estimated from measured encodes. A flat graphic is smaller, a noisy low-light photo larger.
How does 420x525 look on a high-density screen?
On a 2× screen 420x525 is sharp when shown at 210×263 CSS px; shown larger, the browser enlarges it. A slot of 420×525 CSS px on a 2× screen needs an 840×1050 file.
