Twitter Header 1500×500 px 3:1

Frequently Asked Questions

Q: Will resizing make my image blurry?

A: Our tool uses advanced algorithms to maintain sharpness when resizing. Significant enlargements may show quality loss, but reductions generally preserve quality well.

Q: What's better for quality - JPG or PNG when resizing?

A: JPG is better for photographs, PNG for graphics with text or transparency. WEBP offers excellent quality at smaller file sizes for both.

Q: Can I resize multiple images at once?

A: Currently our tool processes one image at a time for optimal quality control, but we're working on batch processing for future updates.
