Resize Image
Change an image's pixel dimensions, with aspect ratio lock
Drop an image here
JPG, PNG or WebP. Photo, signature or a scanned document
Resizing happens entirely in your browser; the image is never uploaded. Pick a preset for the exact pixel size a form asks for, then use the size limit if it also caps the file at 20, 50 or 100 KB. Physical sizes (cm, mm, inches) are converted at the dpi shown, 300 dpi being the print standard portals assume.
About this tool
Changes an image's pixel dimensions to an exact width and height you specify. The aspect-ratio lock keeps the image from stretching by recalculating the other dimension automatically.
Frequently asked questions
›Will resizing reduce quality?
Shrinking an image keeps it sharp. Enlarging it beyond its original dimensions will make it look softer, since no tool can invent detail that wasn't captured originally.
