FAQ

Are images uploaded to your server?

No. The tool uses your browser and Canvas to process images locally on your device.

What image formats are supported?

JPG, PNG, and WEBP are supported in this MVP.

What is the best size for Instagram posts?

Use 1080 x 1080 for square posts, 1080 x 1350 for portrait posts, and 1080 x 1920 for Story or Reel covers.

What is the best size for YouTube thumbnails?

YouTube thumbnails work best at 1280 x 720, a 16:9 landscape ratio.

Can I resize images for Etsy and Shopify?

Yes. This tool includes 2000 x 2000 Etsy listing images and 2048 x 2048 Shopify product images.

Can I batch resize images?

Not in this first version. Batch upload and ZIP export are good next-stage Pro features.

Why does my image get cropped on Instagram or 小红书?

Platforms crop images when your source ratio does not match the post or cover ratio. Use Fit or Blur mode when important edges must stay visible.

Is this tool free?

Yes. The MVP is a free single-image, single-download tool.
