よくある質問 (FAQ)

What are the correct image dimensions for Instagram in 2026?
Square: 1080x1080px (1:1) | Portrait: 1080x1350px (4:5) | Reels/Stories: 1080x1920px (9:16) | Landscape: 1080x566px. Our presets are updated to match current platform specifications.
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.
