Frequently Asked Questions
Yes.
Your JFIF image keeps its pixel dimensions; only the file format changes to PNG.
Lossless editing and compatibility.
PNG is lossless, so later edits do not lose more quality, and it opens everywhere. For photos, expect the PNG to be larger than the JFIF.
No.
The conversion is done locally with the Canvas API.
Detailed Explanation
How it works
The image is decoded onto a canvas and re-encoded to PNG with the Canvas toBlob API.

Use cases
Use it when a site, app or device needs PNG instead of JFIF, or to reduce file size.
- Compatibility and size
Limitations
Converting to a lossy format can reduce quality, and some formats (like HEIC) depend on browser support for decoding.
