Pro Tips
💡Always resize from the original high-resolution image, not from a previously resized version — each resize loses information. Keep your originals untouched.
💡For retina displays, export at 2× the CSS display size. A 400px wide image in CSS needs a 800px source file to look sharp on retina screens.
💡Use WebP format for web output — it is typically 25–35% smaller than JPEG at the same visual quality, and is supported by all modern browsers.
Frequently Asked Questions
Does resizing reduce image quality?
Scaling down preserves quality well. Scaling up causes blurriness — pixels are interpolated. Always work from the largest original available.
Should I lock the aspect ratio?
Yes, unless you need a different aspect ratio intentionally. Unlocking it and entering different proportions will stretch or squash the image.
What format should I save in?
WebP for web (smallest at same quality). PNG for transparency. JPEG for photos where file size matters and transparency isn't needed.
What are common image sizes for social media?
OG/Twitter card: 1200×630. Instagram square: 1080×1080. Twitter header: 1500×500. LinkedIn cover: 1584×396. See the full table above.
