Frequently Asked Questions

Are my images uploaded to a server?
No. All image processing happens entirely in your browser using the Canvas API. Your images never leave your device.
What is the maximum image size?
You can upload images up to 20MB and resize to dimensions up to 10,000×10,000 pixels.
Which format should I choose?
Use PNG for images with transparency or when quality is critical. JPEG is best for photos with smaller file sizes. WebP offers the best compression for web use.
Will resizing reduce image quality?
Enlarging images may reduce sharpness since new pixels are interpolated. Shrinking images generally maintains quality. Use high-quality rendering for best results.
