Compress to an Exact File Size
When an upload form names a limit in kilobytes rather than pixels, start from the number it asks for. Each page below targets one budget and reports the size and dimensions it actually reached.
Resize to an Exact Pixel Size
When the requirement is a shape rather than a file size, start from the dimensions themselves. Each page below outputs exactly one size, and tells you how much of the picture was cropped or padded to get there.
What is Image Resizing?
Resizing changes the pixel dimensions of an image while keeping the whole composition. That makes it different from cropping, which discards part of the picture to change the framing. Reducing dimensions is straightforward: the tool has more source pixels than it needs and can average them cleanly. Enlarging is not — new pixels must be invented by interpolation, which can only guess at detail the camera never recorded. You can work in exact pixels when a platform specifies a size, or by percentage when you want to scale a mixed set of images proportionally.
Why Resize Images?
Most images are used at a fraction of the size they were captured at. A 4000-pixel camera photo displayed in a 600-pixel column forces every visitor to download roughly forty times the data they can actually see. Resizing to the real display size is usually the single largest file-size saving available, and it is also how you satisfy the fixed dimensions that avatars, banners, marketplace listings, and print layouts require.
How to Resize Images
Write down the destination size before you start, and note whether the platform wants a maximum width, a maximum height, or an exact canvas.
