Why do print vendors require JPEG instead of PNG?

Most professional RIP (Raster Image Processor) software used in offset and digital printing handles JPEG reliably. PNG transparency can cause rendering errors, color profile issues, or outright file rejection at many print portals.

Will white background flattening affect my print output?

For assets intended for white-background print pieces (brochures, catalogs, flyers), white flattening is the correct result. If your design has a non-white background, composite the asset before converting.

Are pixel dimensions preserved after conversion?

Yes. Deliteful preserves exact pixel dimensions, which is essential in print workflows where image dimensions determine physical print size at a given DPI.

Can I batch convert a full set of print assets at once?

Yes — up to 50 PNG files per batch, each up to 50MB. This covers typical batch sizes for brochure, catalog, or direct mail production runs.

PNG to JPEG Conversion for Print Production Workflows

Print vendors and prepress workflows routinely require JPEG submissions — PNG files with transparency cause rendering errors in RIP software and are rejected by many print portals. Deliteful converts PNG files to JPEG with automatic white background flattening, preparing assets for print submission.

Print production teams working with marketing collateral, brochures, or catalog files frequently receive PNG assets from designers that include transparency. Most professional printing systems — including those used by offset and digital print vendors — do not handle PNG transparency gracefully at the RIP stage. Converting to JPEG with a white background is a standard prepress step, but doing it for a batch of 30 assets in Photoshop consumes time that should go toward actual prepress work.

Deliteful handles up to 50 PNG files per batch (50MB per file), converting each to JPEG with white background flattening and optimized compression. Image dimensions are preserved exactly — critical in print workflows where pixel dimensions correspond to physical print size at a given DPI. The output is a standard JPEG file accepted by virtually every print portal, PDF workflow, and page layout application.
