Choosing the right dimensions
Not sure what size to use? Here are some common targets: 1200×630 for social media link previews, 150×150 for thumbnails and avatars, 600×200 for email signatures, and 1920×1080 for full-HD backgrounds. When in doubt, check the platform's recommended image dimensions — most publish guidelines.
For web use, smaller is usually better. A 1920-wide hero image is plenty for most screens, and keeping dimensions reasonable means faster page loads for your visitors.
Contain vs Fill explained
Contain mode fits your entire image inside the target dimensions while preserving its aspect ratio. If the proportions don't match, you'll get padding (letterboxing) to fill the remaining space. This is the safe choice when you don't want anything cropped or distorted.
Fill mode stretches the image to exactly match the target width and height, even if that means changing the aspect ratio. Use this when you need pixel-perfect dimensions and don't mind some distortion — or when your source image already has roughly the right proportions.
Batch resizing
Need all your images at the same size? Drop multiple files at once and they'll all be resized to the same dimensions in one go. This is great for preparing product photos for an online store, generating consistent thumbnails for a gallery, or standardizing a set of icons. Every file gets the same width, height, and fit setting you've chosen.

Contain fits the image within your target dimensions while preserving the aspect ratio — if the ratios don't match, white padding is added. Fill stretches the image to exactly fill the dimensions, which may distort it if the aspect ratio differs.
