Frequently Asked Questions

Resizing down (making an image smaller) maintains or improves apparent quality. Resizing up (enlarging) can cause pixelation as the tool must generate new pixels. Our resizer uses high-quality Lanczos resampling for the best possible results in both directions.

Aspect ratio is the proportional relationship between an image's width and height (e.g., 16:9 for widescreen). Locking the aspect ratio means changing one dimension automatically adjusts the other, preventing the image from appearing stretched or squashed. Enable the lock for most use cases.

No. Our image resizer processes images entirely within your web browser using JavaScript and the Canvas API. Your images never leave your device, making it completely private.

The image resizer supports JPG (JPEG), PNG, and WEBP — the three most common web image formats. The output format matches the input format.

Common sizes: Instagram square post 1080×1080px, Instagram story 1080×1920px, Facebook cover 820×312px, Twitter/X header 1500×500px, LinkedIn banner 1584×396px. Set these exact dimensions in the resizer to get platform-perfect images.

There is no strict size limit, but very large images (over 20MP) may take a few seconds to process in the browser. The output file size depends on the target dimensions and chosen format.
