Frequently Asked Questions
Are my images uploaded to a server?+
No. All image processing happens entirely in your browser using WebAssembly. Your images never leave your device.
What resize modes are available?+
You can resize by exact pixel dimensions (e.g. 800x600) or by percentage (e.g. 50%). Aspect ratio is locked by default to prevent distortion.
Can I upscale images?+
Yes, but upscaling may reduce image quality. A warning will appear when the target size exceeds the original dimensions.
Can I change the output format?+
Yes. By default the original format is preserved, but you can convert to JPEG, PNG, WebP, or AVIF via the Output Options panel.
What are the file size and count limits?+
You can process up to 10 images at once, with each file up to 50 MB. Supported input formats are JPEG, PNG, WebP, and AVIF.
