Frequently Asked Questions

How do I resize an image online for free?+
Upload your image, enter the desired width and height (or pick a social media preset), and click Download. The tool resizes your image instantly in your browser — no upload to any server.
Can I resize images for Instagram, YouTube, and other social platforms?+
Yes. The tool includes preset sizes for Instagram Post (1080x1080), Instagram Story (1080x1920), YouTube Thumbnail (1280x720), Facebook Cover (820x312), Twitter Header (1500x500), LinkedIn Banner, Pinterest Pin, TikTok, and more.
Does resizing reduce image quality?+
Enlarging an image can reduce sharpness since new pixels must be interpolated. Shrinking an image generally preserves quality well. The tool exports as high-quality PNG for best results.
Is there a file size or dimension limit?+
There is no hard limit. Very large images (over 10000px) may be slow to process since everything runs on your CPU in the browser. For best performance, images under 5000px work smoothly.
Is my image uploaded to a server?+
No. All processing happens entirely in your browser. Your image never leaves your device.
