Resize Image
Resize an image to exact dimensions, or scale it while keeping its proportions.
About this tool
Upload an image and set a new width and/or height in pixels. Fill in both for an exact size, or just one to scale the image proportionally — handy for fitting an avatar, thumbnail or banner to a specific dimension.
Resizing is done on the server with a high-quality filter, and the result keeps the original format (PNG, JPEG or WebP) where possible. Uploaded images are processed in memory and not kept afterwards.
Frequently asked questions
- How do I keep the image's proportions?
- Enter only a width or only a height and leave the other blank. The missing dimension is calculated so the image isn't stretched.
- Will resizing improve quality?
- No — resizing can't add detail. Making an image larger than the original will look softer. Resizing down is lossless in the sense that it keeps everything in proportion.
- What formats are supported?
- Common formats like PNG, JPEG and WebP. The output keeps the source format when it can, and falls back to PNG otherwise.
