Frequently Asked Questions
- Does this improve the quality?
No. JPEG artefacts already in the file are copied over exactly. PNG only stops further loss from that point on.
- Why is the PNG so much larger?
PNG is lossless. On photographs it is often five to ten times the size of the JPEG. PNG pays off for screenshots, logos and line art, not photos.
- Do I get transparency?
The file gains an alpha channel, but JPEG has no transparency to restore, so the image stays fully opaque.
- Do my files get uploaded anywhere?
No. This tool runs inside your browser tab. The file is read from disk locally and the result is written back locally, so there is nothing on our side to store or delete.
- Is there a size limit?
Images are capped at 100 megapixels, since the browser has to hold the full bitmap in memory. On file count: 8 operations per day without an account, 20 when signed in.
