Frequently Asked Questions
Why resize photos to a specific KB size?
Many government forms, exams, and portals require uploads under strict file-size limits (e.g., 100–200KB). Exact-KB resizing ensures the file passes validation while retaining quality.
Is my image uploaded to any server?
No. All processing happens in your browser using HTML5 canvas and client-side compression. Your images never leave your device.
How do you hit the target size?
We combine quality tuning (binary search) with optional downscaling. If quality alone can't reach the size, we reduce dimensions in small steps while preserving aspect ratio.
Which format should I choose?
JPG is a great default for photos. WebP often produces even smaller files with similar quality. PNG is best for graphics with crisp edges or transparency.
Does this work on mobile?
Yes. The tool is optimized for modern mobile browsers and keeps the interface responsive during heavy processing.
Can I cap the dimensions?
Yes. Set Max width/height to preserve aspect ratio within those bounds—useful when portals also specify maximum pixel dimensions.
