Will resizing for social media crop my image?+
Yes, to fit the exact platform ratio without black bars. We use a smart cover-fill algorithm that centers your subject. You can see a real-time preview before downloading.
Can I resize the same image for multiple platforms?+
Yes. Resize for Instagram, then switch the preset to YouTube or LinkedIn and download a new version — all without re-uploading.
What format is the output image?+
PNG by default for maximum quality. This ensures crisp logos, text overlays, and screenshots. For photos, the visual difference from JPG is negligible at social media display sizes.
