Batch image questions
Which image formats can I batch convert?
The batch converter accepts PNG, JPEG, and WebP images and can export the complete selection in one of those formats.
Can I compress and resize every image together?
Yes. One quality preset and one size setting are applied consistently across the selected batch.
Are the images uploaded to Unidec?
No. Conversion, resizing, and compression run in your browser. You can download results separately or package them into a ZIP locally.
