upscaling images with AI
Is this AI image upscaler free?
Yes. Vermeer AI's image upscaler is completely free to use online. Free accounts receive daily credits that reset every 24 hours. No signup, download, or credit card is required — upload your image and upscale in seconds.
What is the difference between Standard and Ultra modes?
Standard mode is fast and accurate for everyday upscaling tasks. Ultra mode applies a more advanced AI pass that synthesises fine-grained texture and detail, producing sharper and more natural-looking results — ideal for print, large-format display, or heavily compressed source images.
How much can I enlarge an image?
The upscaler supports 1.5×, 2×, 3×, and 4× scale factors. The output pixel dimensions are shown before you process, so you always know exactly what resolution you will receive.
Can I control the style of the upscaling?
Yes. In Ultra mode you can choose between Realistic and Artistic style presets, and fine-tune creativity, detail strength, and similarity with dedicated sliders. An optional text prompt can further guide the enhancement for subject-specific results.
What formats and file sizes are supported?
The upscaler accepts JPG, PNG, WEBP, and HEIC files up to 20 MB. Results are delivered as high-quality PNG files ready to download.
How does AI upscaling differ from traditional interpolation?
Traditional methods like bicubic interpolation simply spread existing pixels further apart, producing blurry results at high magnifications. AI upscaling uses a neural network trained on millions of images to infer and reconstruct fine details that were lost in the original, producing genuinely sharper output.
