Pro Tip: Higher Magnification (up to 8x)
Advanced technique for power users
Our tool supports 2x and 4x upscaling directly. But if you need even higher magnification, you can combine them!
Upscale by 4x First
Upload to our AI Image Upscaler and select 4x
Example: 800×600 → 3200×2400 (4x magnification)
Download & Upload Again
Download the 4x upscaled image, then upload it again to the same tool.
Upscale by 2x Second
This time, select 2x upscaling.
Example: 3200×2400 → 6400×4800 (8x total)
Magnification Options
| Method | Output Size | Total Mag |
|---|---|---|
| 2x Upscaling | 1600×1200 | 2x |
| 4x Upscaling | 3200×2400 | 4x |
| 4x + 2x Combined | 6400×4800 | 8x |
Note: Combining tools uses more credits but achieves higher magnification.
Pro Tip #2: Smart Resizing Workflow
Get exact dimensions you need
AI upscaling only offers fixed multiples (2x, 4x), but sometimes you need exact dimensions. Here's the smart workflow:
Upscale Beyond Target Size
Choose 2x or 4x to get larger than your target dimensions.
Example: Need 1200×800? Upscale 4x to get 3200×2400 (larger than needed)
Use Our Image Resizer
Go to our Image Resizer tool to resize to exact dimensions.
Or directly use our 2K/4K Upscaler to output exact 2K (2048px) or 4K (4096px) resolution in one step!
