100% private — files never leave your device

PNG24 is the common name for 24-bit truecolor PNG — full RGB, no alpha channel (PNG32 adds alpha). It is what most people simply call PNG. Convert photos to JPC for streaming pipelines, or JPC back to JPG/PNG for everyday viewing.

iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

Transparency Full alpha (8/16-bit) Supported
Animation Only via APNG extension Not supported
Metadata tEXt chunks, ICC profile None (bare codestream)
Best for Screenshots, logos, sharp graphics Broadcast streams, archival pipelines

About the PNG24 format

PNG was created in 1996 as a free, open replacement for the patent-encumbered GIF, and it has been the reference lossless image format ever since. Pixels are compressed with the DEFLATE algorithm (the same one inside ZIP files), which reproduces the original image exactly — bit-for-bit — while supporting full 8-bit or 16-bit alpha transparency. Screenshots, logos, icons, charts and anything with text or sharp edges should live in PNG.

Because it never discards information, PNG files of photographs are several times larger than JPG — that is the price of perfection. Modern PNG encoders add filters per scanline that make screenshots and flat-color graphics compress surprisingly well. PNG also became the base of APNG, the animation extension that browsers play natively.

+Strengths

  • ✓Truly lossless — every pixel survives exactly as it was
  • ✓Full alpha transparency with smooth edges, not 1-bit masks
  • ✓Open standard, unpatented, with excellent tooling everywhere
  • ✓Ideal for text, line art and flat-color graphics — sharp edges stay sharp

!Limitations

  • −Photographs become several times larger than JPG
  • −Base format has no animation (that is the APNG extension)
  • −16-bit or high-resolution PNGs can grow very heavy

About the JPC format

JPC is JPEG 2000 stripped to its bare codestream: the same wavelet-compressed image data as JP2, minus the container boxes that give JP2 its metadata, color profiles and file signature. Broadcast and archival systems that stream codestreams directly (rather than storing boxed files) work with JPC.

Because there is no container, JPC carries no thumbnail, no EXIF and no declared colorspace — players must probe the codestream header itself. Converting JPC into JP2 restores a full container; converting to JPG or PNG produces an instantly viewable copy.

+Strengths

  • ✓Wavelet compression, better per-byte quality than JPG
  • ✓True lossless mode available
  • ✓Streamable — no container parsing needed

!Limitations

  • −No metadata, color profile or thumbnail
  • −Browsers cannot open it at all

Why convert PNG24 to JPC?

There is a concrete reason this conversion exists: Photographs become several times larger than JPG JPC sidesteps that — Wavelet compression, better per-byte quality than JPG If that is your situation, the tool above settles it in seconds, entirely on your device.

Frequently asked questions

Is this PNG24 to JPC converter really free?

Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.

Are my files uploaded to a server?

No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.

Does it work on Windows, Mac, iPhone and Android?

Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.

Will I lose quality converting PNG24 to JPC?

No — JPC is a lossless format, so every pixel of the converted image matches your original PNG24 file. You can also adjust the quality/size balance before converting when the target format supports compression.

Can I convert several PNG24 files at once?

Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.

Will transparent areas survive the conversion to JPC?

Transparency is kept whenever JPC actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
