Frequently Asked Questions

How do I resize an image?

Upload your image, then either select a preset size for popular social media platforms or enter custom width and height values. Click Resize to generate your resized image.

What presets are available?

PicKit includes presets for popular social media platforms: WeChat, Xiaohongshu, Instagram, Facebook, and Twitter. Each preset includes common sizes for avatars, posts, covers, and more.

Can I maintain the aspect ratio?

Yes, by default the aspect ratio is locked when you change one dimension. You can unlock it to set custom width and height independently.

Will resizing reduce image quality?

Downscaling (making an image smaller) generally preserves quality well. Upscaling (making an image larger) may result in some blurriness since you're creating pixels that weren't in the original.

Is there a file size limit?

There is no strict file size limit. Processing happens locally in your browser, so performance depends on your device capabilities.
