About
Helvety Image Upscaler enlarges PNG, JPEG, and WebP photos in your browser. AI upscaling runs on your device when supported; otherwise the app falls back to high-quality resizing. Images are not sent to Helvety for processing in the normal flow. Helvety is Switzerland-first and not actively marketed to EU/EEA users; see our Privacy Policy for details.
Access model
Launch the tool without signing in. Usage stays free; automated safeguards keep abusive floods from degrading shared infrastructure.
What you can adjust
- Choose 2× or 4× upscale, or set a target width or height.
- Process up to five images per batch and download them one by one or together.
- The AI model downloads on first use and stays cached for later runs.
- Very large images may be limited so your browser tab stays stable.
Why it fits sensitive screenshots
Frames never leave your session in the supported pipeline, including the AI flow, which makes it easier to audit your own asset workflow when polishing marketing shots or reference stills.
