Frequently Asked Questions
- Can I maintain the aspect ratio while resizing?
- Yes. Toggle the aspect-ratio lock to automatically calculate the matching height or width when you change one dimension.
- What social-media presets are available?
- ToolMint includes 12 presets covering Instagram post/story, Facebook cover/profile, Twitter header, YouTube thumbnail, LinkedIn, and more.
- Will resizing reduce image quality?
- Enlarging an image can reduce sharpness. Shrinking preserves quality well. Use the quality slider to fine-tune the output.
- Can I resize multiple images at once?
- Yes. Upload a batch and apply the same dimensions to all images. Download them individually or as a ZIP.
- Is my image uploaded to a server?
- No. All resizing runs locally in your browser. Your images never leave your device.
