    Dettagli e limiti

    Files are processed in your browser without uploading to a conversion server. No account or watermark.

    Up to 20 files per batch, 20 MB and 40 megapixels each. Images are processed one at a time to limit memory use.

    PNG output can be larger than the JPG source. Converting cannot restore detail already lost in lossy JPG.

    Static images only; animation is rejected explicitly. Metadata such as EXIF is not retained. Color rendering depends on the browser.

    FAQ

    Can I convert several JPG images at once?

    Select up to 20 static images and convert them together. Save successful conversions in one ZIP; a failed file does not discard the others. Repeated filenames receive a numbered suffix.
