Are these image tools free?

Yes. All image tools on Stax are free with no daily limits, no watermarks added to your output, and no sign-up required.

Are my images uploaded to a server?

No. All image processing runs locally in your browser using the HTML5 Canvas API. Your images are never transmitted to any server.

What image formats are supported?

Stax image tools support JPEG, PNG, and WebP input. The image format converter lets you switch between all three; the SVG-to-PNG converter handles SVG input.

Is there a file size limit?

There is no server-side limit. Very large images (50 MB+) may be slow on low-end devices since all processing happens in your browser's memory.

Which image tools are available?

Stax includes an image resizer, compressor, format converter, cropper, meme generator, color picker, photo watermark tool, image-to-PDF converter, and SVG-to-PNG converter.
