Practical answers for preparing artwork with the correct DPI metadata.
No. The converter updates the DPI metadata only, so pixels, compression, and color remain identical to the source file.
Print vendors rely on DPI to calculate physical dimensions. Updating the value ensures their layout software previews the exact size.
Yes. Queue up to 20 files and download them individually or as a single ZIP. Each file keeps its original filename with the DPI indicator.
JPEG and PNG conversions are supported. Both retain transparency and ICC profiles already embedded in the upload.
Never. Everything runs locally via Canvas APIs, so sensitive visuals stay on your hardware.
File size typically stays the same because pixel data is untouched. Only metadata values are updated.
The batch panel uses one DPI target for the queue. If you need different outputs, rerun the converter with a new preset for selected files.
Yes. Embedded ICC profiles and alpha channels remain intact since the converter never re-encodes pixels.
