Resize Image to 800x800
Create an 800 × 800 square for a catalog card, avatar source or application field that specifically requests these dimensions. Pixel dimensions and a file-size limit are separate requirements.

Make a compact square asset
A small source may look soft at 800 pixels. Enlargement is disabled until you allow it. For a logo with transparent margins, select PNG and transparent padding, then inspect the edges on the checkerboard preview.
Create the exact canvas deliberately
Width and height are preselected to 800 × 800 pixels. Upload a JPG, PNG or static WebP image, leave aspect-ratio locking off for the fixed canvas and choose Contain, Cover or Stretch. Contain adds padding; Cover center-crops; Stretch distorts. Upscaling needs your explicit permission when either output edge exceeds the source.
Dimensions, bytes and transparency
The output format and quality determine byte size, which is separate from the selected pixel count. PNG or supported WebP can retain transparency; enable transparent padding when needed. JPEG uses the chosen background. Inputs stay local, with a 25 MiB / ten-megapixel input limit. Download a new copy and inspect it before replacing your original.
Common questions
Does this crop my image automatically?
The initial Contain mode retains the whole image and may add borders. Choose Cover if you deliberately want a center crop.
Will the result meet an upload site's KB limit?
Pixel dimensions alone do not guarantee a byte size. Use Image Compressor afterward and check the destination's actual requirements.
