How to use signature compressor

Understand your requirements

JPG compression removes fine image detail; white paper and dark ink usually compress more easily than textured scans. Flexible dimensions are enabled here and any resulting pixel size is reported. Lock dimensions if your form requires exact pixels.

Good to know

What does signature compressor check?

The exported file is decoded again to check its actual pixels, format, aspect ratio and byte size against your selected requirements.

It confirms the technical requirements you selected. The portal may also check identity, lighting, pose, background or document-specific rules; compare its current instructions yourself.
