How to use Image Upscaling in Qolaba — available upscale options, when to upscale vs. regenerate, and tips for getting the best results.
Image Upscaling increases the resolution and detail of an existing image without regenerating it from scratch. Use it to prepare images for print, large-format display, or any output format that requires higher pixel density than the original generation.
Upscaling processes your image and produces a higher-resolution version with enhanced detail and sharpness. It increases the pixel dimensions of the image by the selected multiplier — 2x, 3x, or 4x — while preserving the composition, subject, and overall visual of the original.
Upscaling improves resolution and clarity — it does not alter composition, change subjects, or fix structural issues in the original image. If the composition or content needs changing, use Image Inpainting → or regenerate with a refined prompt.
Step 1 — Open Image Editing → Upscale from the workspace.
Step 2 — Upload the image you want to upscale, or select one from your generation history.
Step 3 — Select your upscale multiplier — 2x, 3x, or 4x.
Step 4 — Review the credit cost displayed before generating.
Step 5 — Click Generate. The upscaled image is produced and saved to your history.
2x
Standard quality improvement — digital publishing, high-resolution social media, client previews
3x
High-quality print preparation — brochures, posters, A3 and A4 print formats
4x
Maximum resolution — large-format print, billboard, exhibition display, commercial production
Upscaling is the right choice when:
Your prompt, composition, and subject are exactly right and you only need higher resolution
You generated at 1K or 720p during testing and need the confirmed output at print quality
You want to avoid spending credits on a full regeneration when only resolution needs improving
Regenerating at higher quality makes more sense when:
The original image has structural issues, artifacts, or composition problems
You want the model to add more detail during generation rather than after
The subject or scene needs refinement alongside the resolution increase
