Does converting JPG to PNG improve image quality?

Converting JPG to PNG does not recover lost data from JPG compression. However, PNG is a lossless format, so the converted file will not degrade further with repeated saves.

Will JPG to PNG conversion increase the file size?

Yes, PNG files are typically larger than JPG files because PNG uses lossless compression. Expect roughly 2x to 5x larger file sizes depending on image complexity.

Is there a limit on the number of files I can convert?

No. You can convert as many JPG files as you want. All processing happens locally in your browser, so there are no server-side restrictions.

What is the difference between JPG and PNG?

JPG is a lossy format that compresses photos to small file sizes but discards detail and cannot store transparency. PNG is a lossless format that preserves every pixel and supports a full alpha channel, making it the go-to choice for logos, screenshots, and web graphics.

Are my photos safe to convert here?

Yes. Conversion runs entirely in your browser, so your JPG files are never uploaded or stored anywhere. This makes the converter safe for personal photos, client work, and sensitive documents alike.

Is JPG to PNG Converter really instant, or do I have to wait for an upload?

You never wait on an upload. JPG to PNG Converter delivers instant browser conversion — the file is transformed locally on your own device, so your download is ready in seconds instead of sitting in a server-side queue. Large batches finish while you keep working, because nothing is competing for your connection.

Will JPG to PNG Converter add a watermark to my output?

Never. Every file this free online JPG to PNG Converter produces is clean and ready to publish. There is no branding, no watermark and no forced upgrade — the download you receive is the finished file.
