How to resize an image online
Most upload forms want an exact size: a 1080×1080 profile picture, a 1200×630 link preview, a 1920×1080 banner. This tool scales a photo to exact pixels or a percentage, crops it to a preset from the center when the ratio does not match, and saves it as JPEG, PNG or WebP — without sending the file anywhere.
Steps
- 1 Choose an image or drag it onto the box. Its original dimensions and file size appear immediately.
- 2 Pick a preset such as Instagram or Open Graph, or type a width, height or percentage. With the ratio locked, the other side follows.
- 3 Choose the output format and quality, check the preview, and download. The file name carries the new dimensions.
Fill or fit: when the ratio does not match
A 4:3 photo cannot become a 1:1 square without losing something. Fill keeps the exact target size and trims the excess equally from both sides, so the center of the picture survives. Fit keeps every pixel and shrinks the image until it sits inside the box, so one side ends up shorter than the target. The note under the result tells you which one was applied.
Which format should I choose?
JPEG is the smallest for photos and has no transparency — transparent areas are filled with white. PNG is lossless and keeps transparency, which makes it the right choice for logos, screenshots and graphics with text, but files are larger. WebP does both: photo-like compression with transparency, usually 25–35% smaller than JPEG at the same quality. All modern browsers display it.
Enlarging an image
You can scale above 100%, but the browser has to invent the missing pixels, so a small photo blown up to banner size will look soft. Enlarging works acceptably up to about 150%; beyond that, start from a larger original if you can. Shrinking, on the other hand, costs no sharpness — a downsized image looks as crisp as the source.
Privacy and limits
The image is decoded and redrawn on a canvas inside your browser; no file is uploaded and nothing is stored. The limits are 30 MB per file and 10,000 pixels on either side, which is enough for photos straight from a phone or camera. Animated GIFs are flattened to their first frame.
