PNG to JPG converter for stock sites
Drop your Midjourney PNGs — get stock-ready JPEGs: transparency flattened to white, quality of your choice, and the upscale checkbox lifts images to the 4-megapixel minimum Adobe Stock requires. Files are processed in your browser and never uploaded.
How to use
Turn Midjourney PNGs into stock-ready JPEGs.
- Drop one or more PNG files.
- Choose JPEG quality (85–95 is a solid stock range) and optionally upscale to the 4 MP Adobe Stock minimum.
- Download the JPG, then generate metadata in Stock Meta or inspect with the metadata checker.
Files are processed in your browser and never uploaded anywhere.

Why JPG instead of PNG for stock?
Agencies expect JPEG for photos. PNG transparency is useless on white stock canvases and files are heavier.
What happens to transparency?
Alpha is flattened onto white — the usual stock-safe background.
What is the 4 MP rule?
Adobe Stock generally requires at least ~4 megapixels. Enable upscale when exports are below that.
AI content disclosure?
Conversion does not add AI flags. Mark Generative AI on the agency form — see our AI attribution guide.
Batch in the app?
Yes — Stock Meta converts and embeds metadata for large Midjourney batches automatically.
