Come Funziona
Upload an image, set target dimensions or a percentage scale, and choose whether to maintain aspect ratio. The tool resizes using the browser Canvas API and lets you download the result. No server upload required.
Quando Usarlo
- Social media images — resize photos to exact dimensions required by Instagram (1080x1080), Facebook (1200x630), or LinkedIn (1200x627).
- Website thumbnails — create consistently sized thumbnails from images of varying original dimensions.
- Print preparation — resize images to specific pixel dimensions required by print services.
Domande Frequenti
Will resizing reduce quality?
Upscaling (making larger) always reduces quality. Downscaling preserves quality well. For best results, start with the highest resolution source image.
Does it maintain aspect ratio?
Yes, by default. You can toggle aspect ratio lock off to set custom width and height independently, but this may stretch or squash the image.
What output format is used?
The resized image is downloaded as PNG by default, preserving transparency. This works well for web graphics and screenshots.
