About this tool: Free JPG to PNG Converter
Convert JPG images to PNG locally in the browser for sharper screenshots, overlays, and design handoff. No upload required — everything runs locally in your browser for privacy and speed.
Common use cases
- Use PNG when you need crisp UI screenshots or assets that may need transparency later.
- The source image stays in your browser and is redrawn through canvas for export.
Converting JPEG to PNG
Converting JPEG to PNG does not recover detail the JPEG already discarded — but it stops any further loss, and it gives you a lossless file to edit, crop or composite without degrading it again.
When this conversion helps
- 1
Use it as a working format, not a quality upgrade
PNG preserves what is there from this point on. It cannot restore what the JPEG compression threw away.
- 2
Convert before editing, not after
Every JPEG save re-compresses the whole image. Convert once, then edit in PNG as long as you need.
- 3
Expect a bigger file
Lossless storage costs size. If the final destination is the web, convert back to WebP or JPEG at the end.
JPEG to PNG questions
- Does converting to PNG improve quality?
- No. It prevents further loss from additional saves, but the detail the JPEG removed is gone.
- Why did the file get much larger?
- PNG is lossless and JPEG is not, so PNG stores far more data. Use it as a working format rather than the final one.
- Is the conversion local?
- Yes, it runs in your browser and nothing is uploaded.
