Frequently asked questions
Quick answers about privacy, supported formats, 2x/4x/6x/8x scaling, browser requirements, and downloads.
Are my images uploaded?
No. Image processing runs locally in a compatible browser.
Which formats are supported?
JPG/JPEG, PNG and WebP are supported. Results download as PNG to preserve maximum quality.
What is free?
The Free plan supports one image at a time at 2x scale.
What does Pro unlock?
Pro unlocks multi-image batches, 4x, 6x and 8x scale options, ZIP export, and unlimited processing while subscribed.
Is 8x always possible?
Very large source images can exceed browser canvas or memory limits at high scales. ImgUpscyler checks the target size before processing and asks you to choose a lower scale when necessary.
Does upscaling recreate missing detail?
Upscaling can make an image larger and clearer, but it cannot reliably recreate detail that is completely absent from a very blurred or tiny source image.
