Resize images for the web and social posts
Updated: October 9, 2026
Match common width targets, keep aspect ratio, then compress for faster loads — all in the browser.
Huge phone photos slow down sites and get cropped oddly in social templates. Setting width deliberately makes layouts predictable.
Resize locally when you do not want a full-resolution personal photo sitting on a third-party image host just to change dimensions.
Practical approach
- Decide the max width you need (for example 1200px for blog heroes).
- Resize with aspect ratio locked so nothing stretches.
- Compress afterward if the file is still heavy for email or CMS upload.
Upscaling warning
Making a small image larger cannot invent sharp detail. Prefer capturing or exporting at a higher resolution when quality matters.
Need a different format after resize? Use Convert Image (JPG/PNG/WebP) or HEIC to JPG for iPhone originals.
