Which image formats can I use?

You can open JPEG, PNG, and WebP images and create a JPEG, PNG, or WebP result when your browser supports that output format.

Can this tool resize animated images?

No. Animated GIF, PNG, and WebP files are not supported because resizing them in a canvas would not preserve their animation.

Questions about resizing images

Does ScreenText upload my image?

No. Your image is opened, resized, and compressed inside your browser. It is never sent to ScreenText.

Which image format should I choose?

JPEG is a good choice for photos. PNG is useful for logos, screenshots, and transparency. WebP often makes a smaller file while keeping good quality.

Why can the new file be larger?

Changing to PNG, increasing dimensions, or using a high quality setting can make the result larger. The comparison shows this before you download.

Can I resize an animated image?

No. Animated GIF, PNG, and WebP files are not supported because a canvas result would not preserve the animation.

What happens to transparent areas in a JPEG?

JPEG does not support transparency. This tool fills transparent areas with white when you choose JPEG.
