How to use Compress to Target Size
- 1Choose the image that exceeds your file size limit.
- 2Enter your required target size in KB (e.g., 500 for 500 KB) or use the quick preset buttons.
- 3Choose between JPG (standard) or WebP (transparency compatible).
- 4Click "Process images" — the engine iteratively searches for the best quality matching your target.
Adaptive Resolution Scaling
If quality reduction alone is not enough, the engine tries smaller dimensions and reports an error if the target remains unreachable.
Dimension Change Reporting
Clearly reports whether resolution was modified (e.g. 4032×3024 → 2709×2032) alongside final size.
Frequently Asked Questions
What if my target size is very small (e.g., under 50 KB)?
The engine tries lower quality and smaller dimensions. If the target is still unreachable, it shows an error rather than returning an oversized result.
Can I use the result for an application portal?
You can set the portal’s maximum file size, but check the exported dimensions, format and final size against all of its requirements before uploading.
