Frequently asked questions
Quick answers about the free trial, scale options, AI processing, and downloads.
What is imgUpscaler?
An AI image upscaler that enlarges and enhances photos, portraits, product images, artwork, and old pictures directly in your browser.
Is there a free trial?
Yes — a one-time free trial with no account required, so you can see a real AI result before subscribing.
What is the difference between 2x, 4x, 6x and 8x?
2x is a fast, everyday enhancement. 4x is noticeably larger and sharper, good for print. 6x and 8x are for serious detail recovery on professional or restoration work, and also unlock multi-image batches.
Does imgUpscaler change faces?
No — the goal is fidelity, not creativity. Portrait mode is tuned to preserve identity, expression, and natural skin rather than inventing new facial features.
Can I upscale very small images?
Yes. Very small or low-resolution sources are detected automatically and processed with a more careful, restoration-first approach.
What file formats are supported?
JPG, PNG, and WebP uploads. Results download as PNG or JPG.
Do failed jobs use credits?
No. Credits (or your free trial) are only used once a valid, successfully enlarged result is confirmed.
Can I process multiple images at once?
Yes, on Premium and Business plans. The free trial processes one image at a time.
