When you should resize (not compress)
Use resize when a website, app, print shop, or social network asks for a specific width and height. Compressing alone reduces file weight but leaves the pixel dimensions unchanged — forms that reject “image too large” usually mean pixels, not kilobytes.
Pixels vs percent
Pixels are best when you know the target (for example 1080×1080 or 1920×1080). Percent is faster when you only need something half / 70% / double the original for a quick draft. Keep aspect ratio locked unless you intentionally need a stretch.
Fit modes that avoid ugly stretch
- Scale — sizes the whole image to your width/height; may leave empty space if only one side is constrained.
- Padding — keeps the full image visible and fills unused canvas with color or transparency (useful for logos and product shots).
- Crop after resize — when a platform crops from the center, set the final ratio first with the crop tool, then export.
Quality tips
Downscaling usually stays sharp. Upscaling invents pixels and softens detail — enlarge only when a site refuses a small file, and prefer PNG/WebP for graphics with text. Soft export: JPG quality 80–90 for photos, PNG for screenshots with UI.
