How to convert PNG to JPG
- Drop your PNG files on the box above, or click it to choose them (up to 30 at once).
- Check the settings — the quality slider trades file size against detail.
- Press Convert. Each file is processed on your device and shows its old and new size.
- Download the files one by one or take them all as a ZIP.
What changes when you convert PNG to JPG
- The image is decoded and compressed again as JPG at the quality you choose. A small loss of detail is part of lossy compression; at the default 92% it is very hard to see.
- JPG cannot store transparency, so transparent areas are filled with white — what image editors do when saving to JPG.
- Camera details and GPS location (EXIF) are not copied into the new file. Photo orientation is applied to the pixels first, so the result is the right way up.
About PNG and JPG files
PNG is lossless: every pixel is stored exactly, and it supports full transparency. Photos come out large; screenshots, logos and graphics with flat colour stay small.
JPEG is the standard format for photographs. It compresses by discarding fine detail the eye is unlikely to miss, so files are small but every re-save loses a little more. It is a good choice for photos you want to share, upload or email at a small size.
Limits
Up to 30 files of 25 MB each per batch and images up to 50 megapixels — beyond that browsers run out of memory, so the tool says so instead of producing a broken file. Files that are not images, or are damaged, are rejected with the reason.
