Image stretcher
Stretch image for common sizes like 3840×2160
Stretch image for common sizes when the frame is a pixel box: 3840×2160 is a large 16:9, 1080×1080 is square, and 437×897 is a tall size that locking the ratio will not produce from either of those.
Pixel boxes, from 16×16 to 3840×2160
Twelve boxes have a picture. The other thirty-eight are in the table under those pictures. 3840×2160 and 1920×1080 share a shape. 437×897 does not.
One pier at three pixel counts
1280×720. The same pier, fewer pixels.
1280×720 is this pier with fewer pixels. The planks, the boat, and the horizon stay put. A 720p frame is not a crop of a larger 16:9 file.
1920×1080. Full HD of this pier.
1920×1080 is the middle frame. This is the Full HD count of the same pier. A round reflection stays round because width and height scale together.
3840×2160. More pixels, same pier.
3840×2160 is the wide frame on the right. It is a larger copy of the pier, not a wider crop and not a new scene.
These three frames share 16:9. Width and height change by the same factor, so a round reflection on the water stays round. 1024×576, 2048×1152, and 2560×1440 are that shape too, and they sit in the table.
One bowl, three square files
1080×1080. The bowl, composed square.
1080×1080 is the bowl as a square post. The rim is a circle because the file was composed square, not because a widescreen picture was locked.
256×256 and 16×16 in the table are this square, not a new picture. The rim stays a circle at every count until the file is too small to hold the glaze.
The bowl is a different file. Nothing on the pier was squeezed to make it.
800×800. The same bowl.
800×800 is the bowl again. Profile tiles and product squares often ask for this count. The rim is still a circle. Only the pixel count dropped.
512×512. The bowl as an icon.
512×512 is the icon size of this bowl. Stretching down keeps the square and throws away the speckles in the glaze.
A 16×16 or 32×32 icon saved as JPEG grows a halo around the edge. Keep those small squares as PNG. Use JPEG or WebP when the frame is a photograph the size of the pier.
Four files that are not the pier or the bowl
A story, a 4:5 portrait, a 3:2 photograph, and a 4:3 room. Each one was framed for its own box.
1080×1920. The plant, not the pier pulled tall.
1080×1920 is the plant in the window, framed from the pot to the top leaf. A phone story and a vertical wallpaper use this box. Pulling the pier up to this height would smear the boat. This file is not that pull.
1080×1350. The chair, a 4:5 portrait.
1080×1350 is the chair, a 4:5 portrait. It is taller than the bowl and shorter than the plant. The chair was photographed for this frame. It is not the plant with the top and the bottom cut off.
1200×800. The desk, a 3:2 photograph.
1200×800 is the cup and the closed book, a 3:2 photograph. This page has no 1200×628 row. 1200×700, in the table, is a different ratio and will not fall out of this file by locking the proportion.
800×600. The window, a 4:3 frame.
800×600 is the empty room, a 4:3 window that does not fill the wall. 640×480 in the table is this same shape. It is not the pier with the sides squeezed.
Two pulls that miss the box
1500×500. The pier pulled into a strip.
1500×500 is the pier pulled into a strip. The boat is wider than it should be. A round reflection becomes an oval. This is the stretch, and it is the wrong file when the frame was supposed to stay 16:9.
300×250. The bowl pulled wide. Not a square.
300×250 is the bowl pulled slightly wide. The rim is no longer a circle. A medium rectangle is not a square, and locking the bowl's ratio leaves bars instead of this shape.
The other thirty-eight boxes
Some rows match none of these twelve files. They are their own width and height. Open that row on purpose.

| 1200 × 700 | 12:7 | None of the twelve | 12:7. Near the desk's width, not the desk's 3:2. |
| 437 × 897 | 19:39 | None of the twelve | Its own box. Locking 16:9 or the square does not produce 437×897. |
| 1536 × 969 | 512:323 | None of the twelve | Its own box. None of the twelve pictures has this ratio. |

| 800 × 1920 | 5:12 | None of the twelve | 5:12. Not the plant at 1080×1920. |
| 1920 × 800 | 12:5 | None of the twelve | 12:5. Not the pier, and not the 1500×500 pull. |

| 800 × 200 | 4:1 | None of the twelve | 4:1. Wider than the 1500×500 pull, and much shorter. |
| 2000 × 2000 | 1:1 | 1080×1080 | Pixel count only. Same shape as the bowl. |
| 2778 × 1284 | 463:214 | None of the twelve | Wider than the pier. Not 16:9. |

| 1179 × 2160 | 131:240 | None of the twelve | Taller than the plant. Not a 9:16 story. |
| 720 × 1604 | 180:401 | None of the twelve | Taller than the plant. Not a 9:16 story. |

How to stretch an image for common sizes
The tool mixes shapes. The row you tap is the box. Locking the ratio keeps the shape you already have.
- Step 1
Open the largest file you have
A tiny icon is a poor master for a wide frame. Start from the original photograph, then stretch down when the target is an icon.
- Step 2
Tap the pixel row
Squares share the bowl. Wide frames share the pier. The plant, the chair, the desk, and the window are separate rows. The table names every box that does not have a picture.
- Step 3
Look at circles before you save
If a circle has to stay round, crop or lock the ratio. Stretch when the frame has to fill and the warp is acceptable. The strip and the medium rectangle on this page are that warp.
- Step 4
Match the download to the file
PNG for an icon. JPEG or WebP for a photographic wide frame, where a PNG is heavier than the screen needs.
Stretch image for common sizes FAQ
- What does stretch image for common sizes mean here?
- It means filling a known pixel box by changing width and height separately. Twelve boxes have a picture. The table lists the other thirty-eight. The work runs in the browser, and the file stays on this device.
- Does locking the ratio turn a widescreen file into a square?
- No. Locking keeps the shape you started with and leaves bars or a crop. Unlock it and the picture fills the square by compressing width. Circles become tall.
- Is a 4K frame a different shape from Full HD?
- No. Both are 16:9. 4K is a larger copy of that shape. 720p is a smaller copy. The plant's frame is not.
- Where is 437×897?
- In the table, not in the twelve pictures. It is taller than 16:9 and taller than the square. Open that row on purpose. Scaling the pier evenly will not land on it.
- PNG or JPEG for a common size?
- PNG for a small icon square. JPEG or WebP for a photographic wide frame.
