What is PNG?

PNG (Portable Network Graphics) is a lossless image format created in 1996 as a free, open-source alternative to GIF. Unlike JPG, PNG compression preserves every pixel exactly—no quality is lost, no matter how many times you edit and save.

PNG's key features are transparency support and lossless compression, making it ideal for logos, screenshots, graphics, and any image where quality matters more than file size.

While PNG files are larger than JPG for photographs, they're often smaller for graphics with solid colors and sharp edges. PNG has become the standard for web graphics, UI elements, and anything requiring transparent backgrounds.

Why Convert to PNG?

PNG solves specific image needs:

  • Transparency support – PNG handles full alpha transparency, letting images blend with any background
  • Lossless quality – No compression artifacts, perfect for text, logos, and screenshots
  • Repeated editing – Save and edit unlimited times without quality degradation
  • Sharp edges – Text and line art stay crisp, unlike JPG's blur
  • Web graphics – Standard format for logos, icons, and UI elements
  • Screenshots – Preserves exact screen appearance for documentation

Convert to PNG from Other Formats

JPG to PNG

Convert when you need to add transparency or will edit the image repeatedly. Note: converting JPG to PNG doesn't restore quality lost to JPG compression—it just prevents further loss.

WebP to PNG

Extract images from WebP format for editing or when you need maximum compatibility. Transparency is preserved if present in the WebP source.

SVG to PNG

Rasterize vector graphics to PNG at your chosen resolution. Essential when you need a bitmap version of a logo or icon for specific applications.

GIF to PNG

Convert for better color depth (16 million vs 256) and smoother transparency. Note: animation is lost—only the first frame converts.

HEIC to PNG

Convert iPhone photos to PNG when you need lossless quality or transparency. For simpler sharing, JPG is smaller; PNG is for quality-critical uses.

BMP to PNG

Compress BMP screenshots losslessly. PNG is typically 50-70% smaller than BMP while preserving exact quality.

Convert PNG to Other Formats

PNG to JPG

The most common conversion. JPG is 3-10x smaller for photographs. Use when you don't need transparency and want smaller files for email, web, or social media.

PNG to WebP

WebP offers better compression than PNG (25-35% smaller) while supporting transparency. Great for website optimization.

PNG to PDF

Create documents from images. Combine multiple PNGs into a single PDF for sharing or archiving.

PNG to SVG

Convert bitmap to vector for scalability. Works best with simple graphics—complex photos produce large, complex SVG files.

PNG to ICO

Create Windows icons or favicons from PNG images. PNG's transparency makes it ideal as a source for icon creation.

PNG Technical Specifications

  • Full name: Portable Network Graphics
  • Developer: PNG Development Group (1996)
  • File extension: .png
  • MIME type: image/png
  • Compression: Lossless (DEFLATE algorithm)
  • Color depths: 1-bit to 48-bit (including 16-bit per channel)
  • Transparency: Full alpha channel support
  • Animation: No (use APNG for animated PNG)
  • Interlacing: Adam7 progressive display

PNG vs JPG – When to Use Each

  • Use PNG for: Screenshots, logos, graphics with text, images needing transparency, anything you'll edit repeatedly
  • Use JPG for: Photographs, complex images with gradients, images where file size matters more than perfect quality

The rule of thumb: PNG for graphics, JPG for photos. When in doubt about a specific image, try both and compare file sizes and quality.

How to Convert PNG Files

  1. Upload your image – Any format: JPG, WebP, SVG, GIF, HEIC, BMP, or others. Batch upload for multiple conversions.
  2. Select PNG output – For optimal compression, choose between maximum compression (smaller file) or faster processing.
  3. Download your PNG – Get your lossless image with transparency preserved (if applicable).

Conversion is instant and maintains full quality.

PNG Transparency Explained

PNG supports full alpha transparency—each pixel can be fully opaque, fully transparent, or any level in between:

  • Logo overlays – Place logos on any background color seamlessly
  • Product images – Remove backgrounds for e-commerce
  • UI elements – Buttons, icons, and graphics that blend with page designs
  • Soft shadows – Smooth shadow edges that work on any background

When converting from formats without transparency (like JPG), no transparency is added. When converting from transparent formats (like GIF or WebP), transparency is preserved.

Optimizing PNG File Size

PNG files can be large. Here's how to manage size:

  • Use appropriate color depth – 8-bit (256 colors) for simple graphics, 24-bit for photos
  • Consider WebP – For web use, WebP provides 25-35% smaller files with similar quality
  • Reduce dimensions – Resize to the actual display size needed
  • PNG optimization tools – Post-conversion tools like TinyPNG can reduce size further
  • Remove metadata – Strip unnecessary data for web-optimized files

Pro Tip

For web graphics, use PNG-8 (256 colors) for simple graphics with flat colors—files are much smaller than PNG-24. Reserve PNG-24/32 for images needing millions of colors or smooth transparency gradients.

Common Mistake

Using PNG for photographs. Photos typically have millions of colors and compress poorly with PNG's lossless approach. A photo PNG might be 10MB while an equivalent-quality JPG is 500KB.

Best For

Screenshots, logos, graphics with text, UI elements, icons, and any image requiring transparency. Also use for images you'll edit repeatedly—PNG never degrades from re-saving.

Not Recommended

Photographs or complex images with many colors and gradients. These result in unnecessarily large files. Use JPG or WebP for photos where some compression is acceptable.

Frequently Asked Questions

PNG (Portable Network Graphics) is a lossless image format supporting transparency. Unlike JPG, it preserves exact quality through editing. PNG is ideal for logos, screenshots, graphics, and images with transparent backgrounds.

PNG is better for graphics, logos, screenshots, and images needing transparency. JPG is better for photographs and when file size matters. Neither is universally better—choose based on image type and needs.

No. JPG compression already permanently removed data. Converting to PNG preserves current quality and prevents further loss but can't restore what JPG compression removed. Keep originals if quality matters.

PNG uses lossless compression—it preserves every pixel exactly, which requires more data than JPG's lossy compression. For photos, PNG can be 3-10x larger than JPG. The trade-off is perfect quality.

Start with an image that has transparency (or remove the background using an image editor). Save as PNG to preserve transparency. JPG sources have no transparency—you'd need to edit out the background first.

Converting to JPG always involves some quality loss due to lossy compression. At 90%+ quality settings, the loss is invisible to most viewers. Use PNG to JPG when file size matters more than pixel-perfect quality.

PNG is static; APNG (Animated PNG) supports animation like GIF but with full color and transparency. Standard PNG conversion produces static images—animation requires APNG format.

WebP is 25-35% smaller with equivalent quality and supports transparency. For modern websites, WebP is generally better. Use PNG when you need maximum compatibility or are working with older browsers.

Yes. Upload multiple files and batch convert them all to PNG simultaneously. All converted images maintain their original quality and transparency where applicable.

JPG has no transparency, so there's no transparent background to preserve. The white areas in the JPG remain white in the PNG. To create transparency, you need to edit out the background before or after conversion.
