Frequently asked questions
Is the image upscaler really free?
Yes — upscaling on HelloGen is free, with no watermark on the result. There is a fair-use daily limit to keep the service fast for everyone.
How much can I enlarge an image?
The AI upscaler enlarges up to 4×. For the best quality we cap very large uploads, so a typical result lands around 4K resolution.
Will upscaling add a watermark?
Never. Every image you download is clean and full-resolution — HelloGen does not watermark images.
What file formats are supported?
You can upload PNG, JPG or WebP up to 8 MB. The upscaled result is delivered as a high-quality JPG.
Do you store my photos?
Uploads and results are automatically deleted after 24 hours. Download your image before then to keep it.
