About this tool
Whether you need an image to fit a specific pixel size for a website, form, or social profile, this tool resizes it directly on the Canvas API in your browser, with an aspect-ratio lock so you don't accidentally distort the image.
How to use it
- 1Upload an image — its original dimensions are shown.
- 2Enter a new width or height; with "Keep aspect ratio" on, the other dimension updates automatically.
- 3Download the resized PNG.
Common mistakes to avoid
- Unlocking aspect ratio and entering mismatched dimensions, which stretches or squashes the image.
- Upscaling a small image far beyond its original size, which results in visible blurriness since no new detail is created.
Use cases
- Fitting a photo to a required upload size for a form or profile picture.
- Preparing a consistently-sized set of images for a website gallery.
Frequently asked questions
Will resizing reduce image quality?
Shrinking generally preserves quality well. Enlarging beyond the original resolution can look soft, since the tool can only interpolate existing pixels, not invent new detail.
