Frequently Asked Questions
Can I resize images without losing quality?
Our tool uses high-quality bicubic interpolation through the Canvas API. For best results, avoid enlarging images significantly beyond their original size.
What social media presets are available?
We offer presets for Instagram (1080x1080), Twitter (1200x675), Facebook (1200x630), YouTube (1280x720), and LinkedIn (1200x627).
Can I maintain the aspect ratio?
Yes! Use the aspect ratio lock toggle to maintain proportions. When you change width, height adjusts automatically and vice versa.
What formats can I resize?
You can resize JPEG, PNG, and WebP images. The output format matches the input format by default.
Is there a maximum image size?
Processing happens locally in your browser. Most modern devices handle images up to 8000x8000 pixels without issues.
