JPEG to PNG — Edit Photos Without Further Quality Loss

Convert JPEG to PNG to prevent further quality loss from re-saving. Useful as an intermediate file for compositing and retouching.

Local Processing Only

.jpg, .jpeg, .jpe, .jif, .jfif (multiple files)

Format comparison

Source

JPEG (Joint Photographic Experts Group) is the most widely used image format, ideal for photographs and images with gradients.

Pros

  • Universal compatibility
  • Adjustable compression
  • Great for photos

Cons

  • Lossy compression degrades quality
  • No transparency support
Target

PNG (Portable Network Graphics) uses lossless compression and supports transparency. Ideal for logos and screenshots.

Pros

  • Lossless compression
  • Alpha transparency
  • Great for sharp edges

Cons

  • Larger file sizes
  • Inefficient for photos

When to Convert JPEG to PNG

Convert JPEG to PNG for editing workflows. PNG is lossless, which helps avoid accumulating quality loss during repeated saves.

Technical Format Details

JPEG Technical Specifications

Technical details


JPEG is a lossy format optimized for photos. Lower quality settings reduce file size, but can introduce artifacts around edges and text.

Good for

- Photos: Natural images with gradients
- Sharing: Maximum compatibility

Notes

- Re-encoding: Repeated saves accumulate artifacts (use PNG for editing intermediates)
- Transparency: Not supported

PNG Technical Specifications

Technical details


PNG is a lossless raster format that preserves pixel data exactly. It supports alpha transparency, which makes it a common choice for logos and UI assets.

Good for

- Logos/icons: Assets that need transparency
- Screenshots: Crisp text and line art

Notes

- Photos: Files can be large (WebP/JPEG may be a better fit)
- Quality setting: Since PNG is lossless, “quality” controls may have little or no effect

How to Use

1

Add files

Drop or click to select your JPEG files (multiple supported)

2

Confirm output

Default is PNG. You can change to another supported output format if needed.

3

Adjust options

Set quality, resize, and metadata options only if you need them.

4

Convert & download

Download each file, or download everything as a ZIP for batch outputs.

FAQ

Does converting JPEG to PNG improve quality?

No. Data already lost in JPEG can't be recovered.But once in PNG, subsequent re- saves won't cause additional degradation.

Will the file size increase?

Yes. PNG uses lossless compression, so files can be 3–5× larger. After editing, convert back to JPEG or WebP for the final output.

Can I add transparency after converting to PNG?

This converter doesn't remove backgrounds, but you can open the converted PNG in an image editor to add transparency.

Can I keep Exif metadata?

When "Keep Exif/Metadata" is ON, we try to carry over things like capture time, camera info, and GPS where possible. Some tags may be dropped depending on the input, output format, and browser environment. Turn it OFF if you want to remove location data before sharing.

Can I convert multiple files at once?

Yes. You can select multiple files, convert them in one run, and download each file individually. For multiple outputs, you can also download everything as a ZIP. For very large batches, splitting into smaller runs is more stable.

Are my images uploaded to a server?

No. Conversion runs locally in your browser, and your images are not sent to an external server.

What if conversion fails or is slow?

Some formats (like HEIC/HEIF) depend on browser support. If it fails, try another browser, reduce the number of files, or resize before converting.

Why do colors sometimes shift after conversion?

Differences in decoding/encoding and color handling can cause small shifts. For critical images, compare the output against the original.
