Frequently Asked Questions

Will a 1MB compression affect printed quality?

In most cases, no. Text and vector graphics remain at full native printer DPI. Only oversized raster images are downsampled to standard display/print resolutions.

Can I compress larger files (e.g. 50MB) down toward 1MB?

Yes! Scanned books, catalogs, and brochures can often be reduced drastically toward 1MB with our multi-pass optimization.
