Official standards and scope
ITU-T T.81 specifies JPEG coding, the HTML Standard defines browser canvas serialization, and the W3C specification defines PNG. This page accepts any image the browser file picker and decoder can read, draws its decoded pixels at the natural dimensions, and serializes a PNG; it does not verify that the source is JPEG. Original JPEG metadata, profiles, codec settings, and non-pixel data are not deliberately preserved, and browser decoding can affect orientation and color handling. PNG is lossless for the exported pixels but cannot restore detail already lost to JPEG compression.

Notes
- Browser support for JPG to PNG can affect preview and export behavior.
- Large or batch files use more browser memory, so process them in smaller groups when needed.
- Preview the result before using it in production, publishing, or submission workflows.
FAQ
Are images uploaded?
No. Conversion runs locally in your browser.
Is JPG to PNG free to use?
Yes. You can use it directly in the browser without creating an account.
Does JPG to PNG support batch processing?
Image tools with multi-file input can process multiple files. The exact behavior depends on the file picker shown on the page.
Are files or content uploaded?
JPG to PNG runs in your browser, so your input or files are not uploaded to DataHub servers.
Can I use JPG to PNG on mobile?
Yes, but desktop browsers are better for large files, batch conversion, or long text input.
Why can conversion or validation fail?
Common causes include corrupted files, unsupported browser codecs, very large files, or low memory.
Can I use the result commercially?
The tool only processes your own input. Commercial use depends on the rights of the original file or data.
