Frequently Asked Questions (FAQ)

Q1: Is it safe to use this free JPG to PNG converter?

Yes, it is 100% safe. Unlike other online converters, our tool works entirely offline inside your browser using client-side JavaScript. Your images are never uploaded to a server, ensuring total data privacy.

Q2: Will converting JPG to PNG improve image quality?

Converting JPG to PNG preserves the current quality of your image. PNG is a lossless format, meaning no further compression artifacts are introduced. However, it cannot restore quality already lost during JPG compression.

Q3: Can I convert multiple JPGs to PNG at the same time?

Yes. Our tool supports free batch conversion for up to 10 images simultaneously. You can drag and drop a group of files or select them via the file picker, then download them all as a single ZIP file.

Q4: Does JPG to PNG conversion support transparency?

JPG does not support transparency, so the converted PNG will have a solid background. However, the PNG format itself supports transparency, so the converted file can be edited later to add transparency.

Q5: What is the maximum file size allowed?

We support image files up to 10MB per image for batch processing. If your JPEG is larger than 10MB, we recommend resizing its dimensions before conversion.

Q6: Why would I convert JPG to PNG?

PNG is ideal for images requiring lossless quality, such as logos, screenshots, text-heavy graphics, and images with sharp edges. Converting JPG to PNG prevents further quality loss during editing and supports transparency.
