Which Converter Do I Need?
Not sure which tool fits your use case? Here is a quick guide based on what you are starting with and what you need:
| I have… | Use | When to use |
|---|---|---|
| JPG photos | JPG to PNG | When you need lossless quality or want to add transparency. Note: converting from JPG cannot restore data already lost to JPEG compression. |
| WebP images | WebP to PNG | Images downloaded from websites in Google's WebP format. Convert to PNG for universal compatibility and editing in any app. |
| iPhone / iPad photos | HEIC to PNG | Apple HEIC photos to lossless PNG. Use when you need maximum quality preservation or transparency support. |
| SVG vector graphics | SVG to PNG | Rasterize vector logos or icons for use in contexts that do not support SVG (email, social media, older apps). |
| PDF documents | PDF to PNG | Extract PDF pages as PNG images with sharp text. Better than JPG for screenshots of documents. |
| Photoshop designs | PSD to PNG | Export PSD designs to PNG without Photoshop. Preserves transparency from PSD layers. |
| PNG for web (too large) | PNG to WebP | WebP lossless is 25% smaller than PNG. If you need transparency on the web, WebP is the better choice in 2026. |
| PNG photos (too large) | PNG to JPG | Photos stored as PNG are unnecessarily large. JPG reduces file size by 50–80% with minimal visible quality loss. |
PNG Compression & File Size
PNG uses lossless DEFLATE compression — every pixel is preserved exactly. Unlike JPG, there is no quality slider. Instead, PNG offers compression levels (1–9) that trade encoding speed for file size, without affecting image quality:
| Level | File Size | Encoding Speed | Notes |
|---|---|---|---|
| 0 | Largest | Instant | No compression, stored raw. Useful for real-time capture or temporary files where speed matters. |
| 1–3 | Large | Very fast | Light compression. Good for batch processing where encoding speed is critical. |
| 6 | Balanced | Moderate | Default level in most tools. Best trade-off between compression ratio and encoding time. |
| 9 | Smallest | Slowest | Maximum compression. Only 2–5% smaller than level 6, but can be 3–5x slower to encode. Identical decode speed. |
Key insight: All compression levels produce identical image output. Level 9 is only a few percent smaller than level 6. For most users, the default level 6 is optimal. Decode speed is the same regardless of compression level.

PNG Color Depth Guide
PNG supports multiple color depths, each suited for different types of images. Choosing the right color mode can dramatically reduce file size:
| Mode | Colors | Transparency | File Size | Best For |
|---|---|---|---|---|
| PNG-8 (Indexed) | Up to 256 | Binary only | Smallest | Simple graphics, icons, flat illustrations, diagrams. Similar to GIF but with better compression. |
| PNG-24 (Truecolor) | 16.7 million | No | Large | Full-color images without transparency. Photos, complex gradients, detailed artwork. |
| PNG-32 (Truecolor + Alpha) | 16.7 million | Full alpha | Largest | Images needing semi-transparency: logos on varying backgrounds, UI elements, overlays, stickers. |
| Grayscale | 256 shades | Optional | Small | Black-and-white images, X-rays, document scans. 8-bit or 16-bit per channel. |
| 16-bit (Deep color) | 281 trillion | Full alpha | Very large | HDR photography, medical imaging, scientific data. 48-bit color + 16-bit alpha = 64 bits/pixel. |
Rule of thumb: Use PNG-8 for simple graphics with flat colors (icons, logos, diagrams). Use PNG-32 when you need transparency with full color. For photos without transparency needs, consider JPG instead — it will be 5–10x smaller.
Transparency in PNG
Transparency is PNG's killer feature. While JPG has no transparency and GIF only supports binary (fully transparent or fully opaque), PNG supports a full 8-bit alpha channel with 256 levels of opacity:
| Format | Transparency Type | Levels | How It Works |
|---|---|---|---|
| JPG | None | — | No transparency support. Transparent areas are filled with a solid color (usually white) when converting to JPG. |
| GIF | Binary | 2 | Each pixel is either fully transparent or fully opaque. Causes jagged edges on curved shapes ("halo effect"). |
| PNG | Full alpha channel | 256 | Each pixel has an independent opacity value (0–255). Enables smooth anti-aliased edges, drop shadows, glass effects, and gradual fade-outs. |
| WebP | Full alpha channel | 256 | Same quality as PNG with 25–30% smaller file size. Growing browser support (97%+ in 2026). |
Common transparency uses: Logos on any background, product photos with removed backgrounds (ecommerce), UI components (buttons, icons, overlays), watermarks, stickers, app icons, and game sprites. Always save as PNG-32 (truecolor + alpha) for transparency.
PNG vs Other Image Formats
How does PNG compare to other popular image formats? Here is a side-by-side comparison for the same 12-megapixel photo:
| Format | Type | 12 MP Size | Transparency | Animation | Best For |
|---|---|---|---|---|---|
| PNG | Lossless | ~22 MB | Full alpha | APNG | Screenshots, graphics, logos, icons, transparency, pixel-perfect quality |
| JPG | Lossy | ~3 MB (Q85) | No | No | Photos, universal compatibility, web, email, print |
| WebP | Both | ~1.8 MB | Full alpha | Yes | Modern websites (25–35% smaller, transparency + lossy) |
| AVIF | Both | ~1.2 MB | Full alpha | Yes | Next-gen web (50% smaller than JPG, growing support) |
| SVG | Vector | N/A | Yes | SMIL/CSS | Logos, icons, illustrations that scale to any size without pixelation |
| TIFF | Lossless | ~37 MB | Yes | No | Professional print, archival, medical imaging, GIS |
| GIF | Lossless | N/A (256 colors) | Binary only | Yes | Simple animations, memes (not for photos or transparency) |
| BMP | Uncompressed | ~37 MB | No | No | Legacy Windows apps, raw pixel data (mostly obsolete) |
Bottom line: PNG is the standard lossless image format with transparency. For photos, JPG or WebP produce much smaller files. For web transparency with smaller size, WebP is the modern choice. For pixel-perfect screenshots, graphics, and anything requiring exact color preservation, PNG remains the gold standard.
What Is PNG?
PNG (Portable Network Graphics) was created in 1996 as a patent-free replacement for GIF. It has since become the standard lossless image format on the web, used for screenshots, graphics, logos, icons, and any image that needs transparency or exact pixel preservation.
PNG compression works by applying predictive filters (Sub, Up, Average, Paeth) to each row of pixels, then compressing the filtered data with DEFLATE (the same algorithm used in ZIP files). This is completely lossless — the decompressed output is identical to the original, bit for bit.
Key technical facts:
- Standard: ISO/IEC 15948 (W3C Recommendation)
- File extension:
.png - Color depth: 1, 2, 4, 8, 16 bits per channel (up to 48-bit color + 16-bit alpha)
- Color spaces: Grayscale, Indexed (palette), Truecolor (RGB), Truecolor + Alpha (RGBA)
- Max dimensions: 2,147,483,647 × 2,147,483,647 pixels (2^31 − 1)
- Compression: Lossless (DEFLATE), compression level 0–9
- Transparency: Full 8-bit alpha channel (256 levels per pixel)
- Animation: APNG extension (supported in all modern browsers)
- Metadata: tEXt, iTXt, zTXt chunks, ICC color profiles, gamma correction
PNG is universally supported across every operating system, browser, and image editor. While WebP and AVIF offer better compression, PNG remains the go-to format when lossless quality and transparency are required.
