- Preparing an image for a tool or site that requires PNG specifically
- Converting a JPG graphic or screenshot that needs sharp edges preserved
Supported formats and limitations
Accepts JPG or JPEG, up to 20 files at a time.
- PNG is lossless, so no additional quality is lost in the conversion itself — but a JPG's own prior compression artifacts (from when it was first saved) carry over unchanged, since PNG can't recover detail that's already gone.
- PNG files are typically larger than the JPG they came from, since JPG's lossy compression is normally more space-efficient for photos.
- Up to 20 images per batch, 20 MB each.
Frequently asked questions
No — it doesn't add back detail lost when the JPG was first saved. It does mean no further quality is lost in this conversion step, and any future edits saved as PNG won't introduce new compression artifacts.
This is expected. PNG's lossless compression is generally less space-efficient than JPG's lossy compression for photographic images, so the same picture usually takes up more space as a PNG.
No. Conversion happens entirely in your browser using the Canvas API — nothing is sent to a server.
Yes — add up to 20 images and click "Convert" once; each gets its own download button.
No — a JPG has no transparency to begin with, so the resulting PNG is fully opaque, just like the source.
