What's the best size for social media posts?
For Instagram posts, 1080x1080px (square). For Facebook and Twitter, 1200x630px works well. For YouTube thumbnails, 1280x720px is the standard.
Are there any watermarks on the output?
No watermarks, ever. Unlike some other free tools that add branding to your output, Image Resizer gives you clean, watermark-free results every time.
Are my files secure?
Absolutely. Image Resizer processes everything directly in your browser using client-side technology. Your files never leave your device, so your privacy is fully protected.
Will resizing affect image quality?
Downsizing preserves quality — you're just reducing the pixel count. Upsizing beyond the original resolution may result in some softness since the tool needs to interpolate new pixels.
