Frequently Asked Questions
What image formats can I resize?
We support JPEG, PNG, WebP, and GIF formats. You can also choose to convert the format during resize.
Will resizing reduce my image quality?
Our tool uses Lanczos resampling, which provides high-quality results. Enlarging images beyond their original size may show some softness, as no tool can add detail that was not in the original.
What are the social media preset sizes?
We include presets for Instagram posts (1080x1080), Facebook covers (820x312), Twitter headers (1500x500), LinkedIn banners, YouTube thumbnails, and more.
