Many platforms impose double limits: both dimensions (pixels) and file size (KB/MB). E.g., product images need 800×800 and under 2MB; web images need small dimensions and small size for fast loading. You often need to compress both dimensions and size together. Here's how in one step.
Why handle size and dimensions together
File size = pixels × info per pixel, so size and dimensions are strongly linked:
- Resize only: size drops but may stay large
- Lower quality only: limited reduction
- Both together: precise control to meet double limits
Common double-limit scenarios
| Scenario | Dimension | Size |
|---|---|---|
| Product main image | 800×800 | under 2MB |
| Detail page | width ≤ 750px | few hundred KB |
| Web images | by layout | as small as possible |
How to do it with PixelForge
Open the PixelForge Image Compressor — local processing.
Step 1: Upload images (batch supported).
Step 2: Set target dimensions and target size simultaneously. The tool adjusts both.
Step 3: Preview the resulting size and dimensions, then export.
Tips
- Set dimensions before size — dimensions are the hard requirement
- JPG for photos — smaller at equal quality
- Keep originals — double compression is lossy
