What is image to PNG conversion?

PNG (Portable Network Graphics) is a popular bitmap format for storing images. Thanks to its lossless compression, it is ideal for graphics with sharp transitions, text, or logos. Unlike JPG, it supports transparency (alpha channel).

Why convert images to PNG?

Lossless Quality

PNG uses lossless compression, meaning there is no loss of image quality during saving.

Transparency Support

PNG supports an alpha channel, which allows for the creation of images with transparent backgrounds.

Wide Compatibility

PNG is supported by all modern browsers and graphic programs.

How to use this tool?

Upload images - Click the “Browse files” button or simply drag and drop images into the designated area.
Automatic conversion - Images will be automatically converted to PNG format.
Download - Download individual images or all of them at once as a ZIP archive.

Supported Formats

The tool supports conversion from the following formats:

JPG/JPEG - the most widespread photographic format
WEBP - modern format from Google
GIF - animated and static images
BMP - basic bitmap format
TIFF - professional format
SVG - vector graphics

When to use PNG instead of other formats?

PNG vs JPG

Property	PNG	JPG
Compression	Lossless	Lossy
Transparency	Yes (alpha channel)	No
File size	Larger	Smaller
Quality	Maximum	Depends on compression
Suitable for	Graphics, logos, screenshots	Photos

Use PNG for:

Logos and icons
Graphics with text
Screen screenshots
Images requiring transparency
Diagrams and infographics
Images with sharp transitions

Use JPG for:

Photos from a camera
Images with smooth transitions
When you need a smaller file size
Web images (without transparency)

PNG vs WEBP

PNG is an older and more universally supported format, while WEBP offers better compression. PNG is suitable for:

Maximum compatibility with older software
Archiving and long-term storage
Professional printing and graphics
Cases where quality is more important than size

Practical Use Cases

Converting screenshots for documentation

Screenshots from Windows or macOS are usually in PNG format, which is ideal for preserving the sharpness of text and UI elements.

Preparing images for print

High-resolution PNGs (300 DPI) are suitable for professional printing because they preserve every detail.

Web design with transparency

Converting SVG or PSD files to PNG will preserve the transparent background, which can be used on websites.

Archiving documents

Scanned documents saved as PNG will retain text readability better than JPG.

Technical Specifications of PNG

Color Modes

Grayscale - 8 or 16 bits per pixel (shades of gray)
Truecolor - 24 bits (RGB) or 48 bits per pixel
Indexed-color - maximum 256 colors with a palette
Grayscale + alpha - grayscale with transparency
Truecolor + alpha - full colors with transparency

Compression Method

PNG uses the lossless compression algorithm Deflate, the same as ZIP archives. This means:

✅ No loss of quality
✅ Ability to resave repeatedly without degradation
❌ Larger files than lossy formats (JPG, WEBP)

Metadata

PNG supports various metadata including:

Creation and modification date
Copyright and description
Color profile (ICC)
DPI / PPI information
Text annotations

Common Mistakes when Converting to PNG

Unnecessarily large files

❌ Problem: Converting a JPG photo (2 MB) to PNG can create a 15 MB file

✅ Solution: For photos, use JPG. PNG is only suitable for graphics.

Loss of animation from GIF

❌ Problem: A GIF with animation converted to PNG will lose the animation (only the first frame is saved)

✅ Solution: For animations, use GIF or modern formats like WEBP/APNG.

Ignoring transparency

❌ Problem: A PNG with transparency displayed on a white background looks correct, but not on a different background

✅ Solution: Always test PNGs with transparency on various backgrounds.

Optimizing PNG Files

After conversion, you can further optimize PNGs:

Online Tools

TinyPNG - Size reduction by 50-70% while maintaining quality
Kraken.io - Advanced PNG compression
Squoosh - Google tool for optimization

Desktop Tools

PNGGauntlet (Windows) - Batch optimization
ImageOptim (macOS) - Drag & drop optimization
OptiPNG (Linux) - Command line

Frequently Asked Questions (FAQ)

Why is my PNG file larger than the original JPG?

PNG uses lossless compression, which preserves all data. JPG uses lossy compression, which removes details for a smaller size.

Can I convert an animated GIF to PNG?

Yes, but only the first frame will be saved. To preserve animation, use APNG or WEBP.

Does PNG support transparency?

Yes, PNG supports an alpha channel with 256 levels of transparency (unlike GIF, which only has 1 bit of transparency).

Will I lose quality when converting from JPG to PNG?

No, but you won't regain quality. PNG will preserve the JPG quality, but it cannot restore details lost during the original JPG compression.

Is PNG suitable for photos?

Generally no, due to large file sizes. For photos, JPG (web) or TIFF (archiving) is better.

Do all browsers support PNG?

Yes, PNG is supported by all modern and older browsers since the 90s.
