Frequently Asked Questions

What image formats are supported?

You can upload JPG, PNG, WEBP, GIF, BMP, and SVG images. All processing happens in your browser — nothing is uploaded to our servers.

What are the available platform presets?

We provide presets for Instagram (Post, Story, Landscape), Twitter/X, Facebook, LinkedIn, YouTube, TikTok, WhatsApp, Pinterest, and common standard sizes like Full HD and 4K.

What is the difference between Fill, Fit, and Stretch?

Fill scales and center-crops the image to exactly match the target dimensions — ideal for social media. Fit scales the image to fit entirely within the bounds with padding. Stretch forces the exact dimensions and may distort the image.

Can I set a custom image size?

Yes. Enter any width and height in pixels. Use the lock icon to maintain the original aspect ratio while resizing.

Which output format should I choose?

JPG is best for photos and social media posts. PNG is ideal when you need transparency. WEBP offers the best compression with high quality for web use.
