Resize images online
Resize JPEG, PNG, WebP, AVIF, BMP, TIFF, GIF, HEIC, HEIF, or SVG images by pixels, percentage, screen preset, or print size and DPI without uploading them.
How to resize an image locally
Open one image, choose exact pixels, a percentage, a named display resolution, or print dimensions and DPI. Generate the result to see its exact encoded size, then download it or continue in another local image tool.
Choose interpolation for photos or pixel art
Balanced MKS2013 is a strong default, Lanczos 3 gives a smoother photographic result, and nearest neighbour keeps hard pixel edges. Enlargement interpolates pixels but does not restore missing detail.
Pixels, print size, and DPI
Print dimensions and DPI determine the required pixel dimensions. JPEG, PNG, BMP, and TIFF can store the chosen DPI; WebP, AVIF, and GIF use it only for the pixel calculation.
Private browser processing
The file, pixels, dimensions, and generated result stay in your browser. Nothing is uploaded, and transfers to another a11.tools image utility happen only after an explicit action.
