Frequently Asked Questions
Does changing DPI also change pixel dimensions?
No. DPI is print-resolution metadata. Pixel dimensions are controlled separately with the width and height fields.
Can both JPG and PNG store DPI?
Yes. JPG results use JFIF density metadata, and PNG results use pHYs physical resolution metadata.
Can I change DPI for multiple images at once?
Yes. Upload multiple images, set one DPI and pixel rule, then download individual files or a ZIP.
Supported Scope
Upload JPG, PNG, WebP, or HEIC images, then write DPI metadata into JPG or PNG outputs while adjusting pixel dimensions.
