Does resizing PNG preserve transparency?

Yes! Our resizer fully preserves the alpha transparency channel. All transparent and semi-transparent areas remain intact after resizing.

Why are resized PNG files so large?

PNG uses lossless compression, which preserves every pixel perfectly but results in larger files. After resizing, consider compressing the PNG or converting to WEBP for smaller files.

Should I resize PNG or convert to JPG first?

If your image needs transparency, keep it as PNG. If not, converting to JPG before resizing can result in smaller files, but you will lose the transparency channel.
