Convert JPG to PNG
Plenty of tools — sprite pipelines, document systems, older upload forms — only accept PNG. Converting a JPG to PNG wraps your image in a lossless container that every application can read, without any further quality loss from this point on.
The conversion runs entirely in your browser, preconfigured for PNG output. One honest note up front: converting to PNG cannot restore detail the original JPG compression already discarded — it prevents future loss, not past loss.

How it works
Select one or more images.
Choose the target format; consequences (like losing transparency in JPEG) are shown before converting.
Pick a background color if converting transparency to JPEG.
Convert and download individually or as a ZIP.
What the tool does
- PNG, JPEG, and WebP output
- Batch conversion with per-file success/failure isolation
- Explicit background selection when alpha meets JPEG
- Quality control for lossy targets
- ZIP download with deterministic file naming
How the result is verified
Every output is re-decoded to confirm it parses as the target format with the expected dimensions; failures are isolated per file.
Frequently asked questions
Will converting to PNG improve my image quality?
No — and any tool that claims otherwise is misleading you. PNG stores exactly the pixels the JPG decodes to. It stops further generational loss if you keep editing, but existing JPG artifacts remain.
Why did my file get so much bigger?
PNG is lossless, so it can't use the aggressive perceptual compression JPG uses. For photographs a large size increase is normal and expected.
