Frequently Asked Questions
1. What's the best format for scanned signatures?
PNG with transparent background (72dpi resolution). This maintains clean edges without white boxes around your signature.
2. How can I reduce file size without losing quality?
Use these settings: JPEG quality 80-85%, PNG 8-bit for signatures, and proper dimensions (never resize up from smaller images).
3. Why does my resized image look blurry?
This happens when enlarging small images. Always start with highest quality source and resize down only.
Pro Tips for Perfect Resizing
- Maintain Aspect Ratio: Lock width/height proportion to prevent distortion
- Resolution Matters: Use 300dpi for print, 72dpi for digital documents
- Batch Processing: Resize multiple images to consistent dimensions
