Frequently asked questions

My form requires 100 KB or less. Will this pass?

Yes, provided the image is compressible. TargetKB guarantees the output stays under 100 KB and gets as close to it as the image allows, so you don't waste quality or get rejected.

My image is already under 100 KB.

TargetKB detects this and does not recompress — re-encoding an already-small image can only make it worse. You simply download the original.

Do you upload my image to a server?

No. Compression runs locally in your browser. Nothing is uploaded, so it is safe to use with documents that contain personal data.
