JPG or JPEG · up to 20 files · 20 MB eachHow to use this tool
- Add your JPG files. Drop them onto the box or browse. You can queue up to 20 images, and each one may be as large as 20 MB.
- Review the queue. File names and sizes appear in the list. Remove any image you added by mistake before starting.
- Press Convert to PNG. Every file is decoded and redrawn at its original width and height, then encoded as a lossless PNG.
- Check each result. The list marks every image as done and shows the new size; failed files explain what went wrong.
- Download. Save files individually, or use Download all (ZIP) to grab the whole batch in one archive.
Why use this tool
Some editors and print shops treat JPG as a delivery format and ask for PNG as the working format. Renaming the extension does nothing; the bytes inside still say JPEG. This converter decodes the picture and writes a real PNG container, so the file opens as PNG everywhere and can be edited without another round of JPG compression each time you save.
Photos do not shrink when they become PNG, and it is worth being honest about that: a 2 MB JPG often turns into a 10 MB or larger PNG. What you gain is exact pixel data plus the option to add transparency later. For screenshots, logos and line art, the result is usually crisp and convenient. Converting locally also means a folder of client photos is never uploaded to an unfamiliar service.
