About this tool
This converter re-saves a JPG (JPEG) image as a PNG. PNG uses lossless compression, so no further quality is lost in the conversion, and it supports transparency for images that need it later. The image is decoded and re-encoded with the Canvas API inside your browser, so it is never sent to a server. Note that a PNG made from a JPG is usually larger than the original, because PNG does not discard detail the way JPG does.
Benefits & use cases
- Get a lossless copy for further editing without generation loss.
- Produce a PNG for tools or sites that require that format.
- Prepare an image that may later need a transparent background.
- Keep sharp edges on screenshots and graphics.
Frequently asked questions
Is my image uploaded anywhere?
No. The conversion happens in your browser with the Canvas API and the image never leaves your device.
Will the PNG look better than the JPG?
No. Converting can't recover detail JPG already removed. PNG just stops any further loss from re-saving.
Why is the PNG file bigger?
PNG stores every pixel exactly, while JPG compresses aggressively. For photos, PNG files are normally several times larger.
Can I convert many images at once?
This tool converts one image at a time. Repeat the steps for each file.
