Frequently Asked Questions
What image formats are supported for upload?
You can upload PNG, JPG/JPEG, and WebP images. The output can also be exported as JPG, WebP, or PNG.
Does this tool upload my images to a server?
No. All resizing is done entirely in your browser using the HTML5 Canvas API. Your images never leave your device.
What is the maximum number of images I can upload at once?
You can upload up to 10 source images at a time. Each image can be resized to all 20+ platform presets simultaneously.
What is Cover vs Contain vs Stretch mode?
Cover fills the entire target frame by cropping the excess (best for most social posts). Contain fits the whole image inside and adds a background padding. Stretch resizes without preserving the aspect ratio.
What are the correct Instagram image dimensions?
Instagram supports 1080×1080px (square), 1080×1350px (portrait), 1080×566px (landscape), and 1080×1920px (Stories/Reels).
Can I add my logo as a watermark?
Currently the watermark supports text overlays. You can customize the text, font size, color, opacity, and position (corners or center).
How do I export all sizes at once?
Click the Download ZIP button in the toolbar. All selected presets will be exported into a structured ZIP file with platform subfolders.
