Frequently Asked Questions
- What happens to transparent pixels?
JPEG has no alpha channel, so transparency is filled with a background colour. White is the default and you can change it.
- How much smaller will it be?
For photographs, usually 80 to 95 percent smaller. For flat-colour graphics the gain is small and the edges get worse.
- Can I go back to PNG afterwards?
You can convert back, but the discarded detail is gone for good. Keep the PNG if you may need to edit it later.
- 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.
