Frequently Asked Questions
You can upscale images up to 8x their original resolution, with a maximum output of 16,000 × 16,000 pixels. For best results with 8x upscaling, start with at least 500×500px sharp images. Very small or blurry images work better at 2x or 4x.
ESRGAN is fastest and best for general photos and quick previews. Clarity uses AI to creatively enhance details, perfect for faces and artistic images. Topaz offers 7 specialized variants: Standard (general), High Fidelity (maximum detail), Recovery (damaged images), Low Res (tiny images), CGI (3D renders), Text Refine (documents), and Redefine (creative enhancement).
ESRGAN costs just 1 credit for most images (up to 48 megapixel output), or 2 credits for very large outputs. Clarity and Topaz use dynamic pricing based on output megapixels. The exact cost is shown before you process.
AI upscaling enhances detail and reduces noise, but it works best on sharp, low-resolution images. For blurry or out-of-focus photos, results vary. The Topaz Recovery variant is designed to help with heavily compressed or damaged images.
Compare All processes your image with all three AI models simultaneously, showing results side-by-side. This helps you pick the best output for your specific image without guessing which model works best.
Yes! All models preserve transparency in PNG images. This is perfect for upscaling logos, icons, and product images with transparent backgrounds that you've processed with our background removal tool.
Use our Batch Upscaling tool to process unlimited images. You can upload files directly, import URLs from CSV/Excel, or connect to Google Sheets. Each image uses the same model and scale settings.
If you pick an image from Sirv or have Sirv connected, you'll see 'Upload to Sirv' after processing. Save alongside the original, replace it, or choose a custom path. The upscaled image is instantly available on Sirv's global CDN.
