FAQ

Image Resizer — frequently asked questions

Does resizing an image reduce its quality?
Downsizing uses high-quality bicubic resampling — indistinguishable from the original at typical screen sizes. Upsizing beyond the original resolution does introduce softness.
Can I keep the original aspect ratio?
Yes. Aspect-ratio lock is on by default — unlock it only if you need to stretch the image.
What input formats does the resizer accept?
JPEG, PNG, WebP, GIF, and most common image formats your browser can decode.
Are the social media sizes up to date?
Yes. Presets track the current recommended dimensions for Instagram, Twitter/X, YouTube, LinkedIn, and Facebook.
