Frequently Asked Questions
What image formats can I resize?
Our tool supports JPG, PNG, and WEBP formats. You can resize any image in these formats without quality loss when maintaining dimensions.
How do I maintain aspect ratio when resizing?
Use our preset ratios or lock the aspect ratio toggle. When locked, changing either width or height will automatically adjust the other dimension to maintain the original proportion.
What are the recommended sizes for social media?
We provide presets for all major platforms: Facebook Profile (180×180), Cover (820×312), Instagram Profile (110×110), Post (1080×1080), Twitter Header (1500×500), and more.
Will resizing affect image quality?
When enlarging images significantly, some quality loss may occur. For best results, start with high-resolution images and only reduce size. Our tool uses high-quality resampling algorithms.
Is there a file size limit?
There's no strict limit, but very large images (50+ MP) may take longer to process. For best performance, we recommend images under 20MP.
