When to Convert JPG to PNG
- Preparing images for further editing in tools that handle PNG better (layer support, no quality loss on re-save)
- Creating graphics with future transparency needs — convert to PNG first, then edit in Photoshop/GIMP
- Archiving important photos in lossless format to prevent further quality degradation
- Converting profile photos or logos that need clean edges without JPG compression artifacts
- Preparing images for print where lossless quality is required by the print shop

//how_it_works
How It Works
Drop your JPG files
Drag and drop or select JPG/JPEG images from your device. Any JPG file works — from phone photos to web downloads.
Lossless decoding
Your browser's native JPEG decoder reads the image and renders it at full resolution onto an HTML Canvas element. No quality is lost in this step.
PNG export with alpha
The Canvas exports as a 24-bit PNG with full alpha channel support using lossless DEFLATE compression. Every pixel is preserved exactly.
Download lossless PNGs
Your PNG files are ready for editing, printing, or archiving. Future re-saves won't degrade quality since PNG is lossless.
// under the hood
JPG uses lossy DCT compression that permanently discards image data. Converting to PNG wraps the image in lossless DEFLATE compression — this preserves the current quality but cannot restore data lost during the original JPG compression. Our converter renders the JPG onto a Canvas and exports as 24-bit PNG with full alpha channel support.

Frequently Asked Questions
- Why convert JPG to PNG?
- PNG is a lossless format, so further edits won't degrade quality like they would with JPG. PNG also supports transparency, making it ideal for logos, graphics, overlays, and images you plan to edit further.
- Will the file size increase?
- Yes, PNG files are typically larger than JPGs because PNG uses lossless compression. For photographs, a PNG can be 2-5x larger than the JPG equivalent. This is the trade-off for perfect quality preservation.
- Can I add transparency after converting?
- The conversion preserves the image as-is — a white background stays white. However, once in PNG format, you can edit the image in any image editor to remove backgrounds or add transparency.
- Does the conversion improve image quality?
- Converting JPG to PNG doesn't restore quality lost during the original JPG compression. However, it prevents any further quality loss from future edits or re-saves, since PNG is lossless.
- Is this tool really free?
- Yes, completely free with no limits. There's no signup, no watermark, and no hidden fees. We're able to offer this because the conversion runs entirely in your browser — there are no server costs.
