Frequently Asked Questions
- Does resizing preserve the aspect ratio?
- Yes. The tool automatically calculates the correct height based on your target width to maintain the original proportions.
- Can I resize to a specific height instead of width?
- Currently the tool scales by width with aspect ratio locked. Use the Image Crop tool if you need specific dimensions.
- What formats can I resize?
- JPEG, PNG, and WebP are supported. HEIC files can be converted first using the HEIC to JPG tool.
