Häufig gestellte Fragen

How do I resize an image online for free?
Drop your image into the resizer, enter the target width or height (or choose a preset), and click Resize. The image downloads to your device immediately.
Can I resize without distorting the image?
Yes — enable "Lock aspect ratio" to proportionally scale the image. Changing the width will automatically update the height and vice versa.
What are common social media image sizes?
Instagram post: 1080×1080 px. Facebook post: 1200×630 px. Twitter/X card: 1200×675 px. LinkedIn post: 1200×627 px. YouTube thumbnail: 1280×720 px.
Will resizing reduce image quality?
Downscaling (making an image smaller) generally preserves quality. Upscaling (making it larger) may soften the image — use our Upscale Image tool for AI-quality enlargements.
Are my images safe when I resize them here?
Completely safe. All resizing runs in your browser using the Canvas API — no server upload, no storage, complete privacy.
