💡 Tips for resizing
- Start large, resize down. Enlarging a small image makes it blurry. Always start from the highest resolution you have.
- Maintain aspect ratio. Use the "keep ratio" option to avoid distortion when entering one dimension.
- Compress after resizing. Resize first to reduce pixel count, then compress to reduce file size further.
- Use PNG for graphics with text (logos, infographics) and JPG or WEBP for photos.
