Specifications

Output format: PNG (Portable Network Graphics)
Compression type: Lossless DEFLATE (ZIP-like)
Transparency: Full 8-bit alpha channel
Color depth: 24-bit RGB (16.7M colors)
Best for: Graphics, logos, text, screenshots

The Challenge

JPG compression destroys logo quality—sharp edges become blurry, text develops artifacts, flat colors show noise. Screenshots saved as JPG make UI text unreadable. WebP files won't open in Photoshop CS6 or older design tools. Email clients block AVIF attachments. PNG solves all: lossless compression preserves every pixel through unlimited edits. Transparency support enables overlays without white boxes. Universal compatibility—every image editor, browser, and application supports PNG since 1996. Critical for workflows: Design iteration (edit/save 50 times without cumulative quality loss). Logo distribution (transparent backgrounds work on any website color). Screenshot documentation (text remains sharp at 100% zoom). Format standardization (clients can open PNG regardless of their software).

Best Practices

Never convert JPG photos to PNG for web deployment—files balloon 3-10× with zero quality gain. Use PNG only as intermediate editing format, export back to JPG/WebP for final delivery
Tool auto-selects PNG-8 (256 colors) for simple graphics—90% smaller than PNG-24. Icons, logos with flat colors compress dramatically. Complex photos always use PNG-24 (16.7M colors)
Logos and icons workflow: Convert to PNG → PNG Compress tool → 70-80% smaller files while remaining perfectly lossless. Uncompressed PNGs from converters are bloated
Preserve WebP/AVIF transparency by converting to PNG—achieves universal compatibility (IE11, old Android) while maintaining alpha channel for overlays and compositing
Convert screenshots to PNG immediately after capture—preserves UI text sharpness critical for documentation. JPG screenshots blur text into unreadability after compression artifacts
Master design files: Keep as PNG for unlimited edit cycles without cumulative JPG quality degradation. Export derivatives (web, email) to smaller formats from PNG master
GIF to PNG conversion preserves transparency and first frame only—animation lost. For static GIF graphics (not memes), PNG provides better compression and color depth
Browser converter outputs 8-bit PNG (24-bit RGB)—sufficient for web and general use. Professional 16-bit PNG (48-bit RGB) requires specialized tools for RAW photo workflows
PNG supports gamma correction and color space metadata—ensures consistent appearance across devices. JPG often displays darker/lighter depending on viewer software
For e-commerce product photos with transparency (clothing on transparent background), convert to PNG for Shopify/WooCommerce upload—platforms handle format optimization automatically

Frequently Asked Questions

When should I use PNG instead of JPG or WebP?

Use PNG for: logos with transparency, icons, graphics containing text, UI screenshots, diagrams, images requiring multiple edits, anything needing pixel-perfect quality. Use JPG for: photos, images without transparency, web photos where 40-60% size reduction matters. Use WebP for: modern web photos balancing compression and quality. PNG photos are 3-10× larger than JPG—wastes bandwidth without visual benefit unless transparency or editing workflow required.

Will converting compressed JPG to PNG improve quality?

No—conversion cannot recover data discarded during original JPG compression. Converting JPG to PNG stores existing compressed/lossy data in lossless container—produces 3-10× larger file with identical visual quality. JPG compression permanently removes high-frequency detail—PNG conversion doesn't restore it. Only convert JPG to PNG if: preparing for extensive editing where cumulative JPG re-compression losses matter, or need to add transparency to existing image.

Why is PNG file 10× larger than original JPG photo?

PNG uses lossless DEFLATE compression—preserves every pixel without data loss. Photos with complex color gradients compress poorly losslessly. Example: 500KB JPG photo (discarded 90% of data through lossy compression) becomes 5-8MB PNG (keeps all data). Solutions: 1) Use PNG Compress tool (40-70% reduction, still lossless), 2) Accept PNG isn't optimal for photos—convert back to JPG at 85% quality or WebP for web, 3) Use PNG only for images genuinely needing lossless quality or transparency.

Does PNG support animation like GIF files?

Standard PNG: no animation support. APNG (Animated PNG) exists with limited adoption—Firefox/Safari support, Chrome added 2017, IE never supported. For animation needs: GIF (256 colors, universal support since 1987), WebP animation (better compression, 95% browser support), MP4/WebM video (for clips over 5 seconds). Converting animated GIF to PNG extracts first frame only—animation discarded. Multi-frame GIFs export as PNG sequence (separate files per frame).

Can I convert transparent WebP/AVIF to PNG for older browsers?

Yes—primary PNG conversion use case. WebP/AVIF offer 25-50% better compression but fail in IE11, Safari pre-14, old Android browsers. Converting to PNG preserves alpha channel while ensuring universal compatibility. Trade-off: PNG files 2-4× larger than WebP. Best practice: serve WebP/AVIF with PNG fallback via <picture> element—modern browsers get compressed version, legacy browsers get compatible PNG. Example: <source type='image/webp'><source type='image/png'>.

What happens to EXIF data when converting to PNG?

Canvas API strips all EXIF metadata during conversion—GPS coordinates, camera settings, timestamps, copyright info removed. PNG format supports tEXt chunks for metadata but browser Canvas doesn't preserve them. This is privacy benefit for most users (prevents location tracking). For preserving EXIF in professional photography workflows, use command-line tools (ImageMagick, ExifTool) or desktop software (Photoshop, GIMP) instead of browser converters.

Is PNG-8 or PNG-24 better for logos and graphics?

Depends on color count. PNG-8 (256 colors, 8-bit palette): 70-90% smaller, perfect for logos, icons, flat graphics with limited colors. PNG-24 (16.7M colors, 24-bit): required for photos, gradients, complex graphics. Our tool auto-detects: analyzes source image, outputs PNG-8 if under 256 unique colors, otherwise PNG-24. Manual control unavailable in browser converters—use Photoshop 'Save for Web' for explicit PNG-8/PNG-24 selection.

Why does my PNG look different on iPhone vs Android?

PNG gamma and color space handling varies between devices. PNGs contain gamma correction metadata (gAMA chunk) and color profile (iCCP chunk)—devices interpret differently. iOS tends toward slightly lighter rendering, Android slightly darker. Browser converters strip color profiles for smaller files—causes inconsistency. Solutions: 1) Accept minor variations (typically imperceptible), 2) Use sRGB color space in source images, 3) For critical color accuracy (product photos), embed color profiles using desktop tools before conversion.
