A Practical Guide to Resizing Images
Resizing changes pixels, not just file size
Resizing changes the width and height of an image in pixels. File size follows indirectly: halving both the width and the height leaves only a quarter of the pixels, so the file usually becomes much smaller too. If a form or website complains that your photo is too big, resizing is often the most effective fix.
Common target sizes
- Instagram feed post: 1080 × 1080 px (square) or 1080 × 1350 px (portrait)
- Instagram or Facebook story: 1080 × 1920 px
- YouTube thumbnail: 1280 × 720 px
- Full HD wallpaper or slide: 1920 × 1080 px
- Blog or article image: around 1200 px wide is plenty for most layouts
Keep the proportions yourself
Width and height are set independently, so entering numbers that do not match your photo's shape will stretch it. To keep the proportions, work out the new height with this formula: new height = new width × (original height ÷ original width). For example, a 4000 × 3000 photo resized to 1200 px wide should be 900 px tall.
Shrinking is safe, enlarging has limits
Making an image smaller keeps it sharp. Making it larger cannot add detail that was never captured, so the browser estimates the new pixels and the result looks softer. A modest increase is fine, but doubling or tripling the size will be noticeably blurry. Everything happens locally in your browser, so your photos are never uploaded.
