What this tool does
Decodes your JPG and re-encodes it as a lossless PNG file. The PNG will be larger than the JPG but will not degrade further on re-save. Supports transparency on pixels that have been manually made transparent in an editor.

Image tools guide for jpg to png converter users.
PNG is lossless, meaning once you convert to PNG the current pixel values are preserved exactly — no further quality loss occurs even if you re-save the file many times. This makes it ideal as a working format for images you plan to edit.
Converting a JPG to PNG does not restore quality that was lost when the JPG was originally saved. If the original JPG has compression artefacts, those artefacts will still be present in the PNG — just frozen in place. To get a genuinely lossless image, you need to start from the original source file (a RAW photo, a PSD, a vector file).
PNG files are larger than JPGs for photographic content. Use this conversion when you need the transparency support or lossless re-editing capability of PNG, not to reduce file size.
How to use it
Upload your JPG, select PNG as the output, and click Convert. Download the PNG file. Batch upload is supported for converting multiple JPGs at once.
Best practices
Use JPG→PNG when you need to edit an image repeatedly without quality loss. Avoid it for final web delivery — PNG files are much larger than JPG for photos. Use PNG for logos, icons, and graphics; JPG or WEBP for photographs.
Quick checklist
- Confirm the input file, value, text, or measurement is correct before running the tool.
- Use the visible dropdowns and settings to choose the output format, unit, quality, size, or result style.
- Check the preview, result text, or downloaded file before using it for important work.
- For private or sensitive data, prefer browser-based tools and avoid uploading files unless the tool clearly needs server processing.
Answers
JPG to PNG Converter FAQs
Does converting JPG to PNG improve the quality?
No. JPG compression artefacts are baked in when the file is saved. Converting to PNG freezes the current quality permanently but cannot recover lost detail.
Why is the PNG file so much larger?
PNG is a lossless format that stores every pixel precisely. For photographs, this requires significantly more data than JPG's lossy compression. A 500 KB JPG photo may become a 3–5 MB PNG.
Does PNG support transparency?
Yes — PNG supports an alpha channel for full and partial transparency. JPGs do not. If you need a transparent background, PNG is the correct format.
Is my image uploaded anywhere?
No. This tool runs entirely in your browser using the Canvas API. Your image never leaves your device.
Which format should I use for a logo?
SVG if the logo is vector-based (crisp at any size, tiny file). PNG if you have a raster (pixel-based) logo and need transparency. JPG is wrong for logos — it blurs edges and creates artefacts.
