Image File Formats: Choosing Between PNG, JPEG, WebP, ICO, and More

Every image format makes different trade-offs between file size, quality, features, and compatibility. Understanding these trade-offs helps you choose the right format for every situation. JPEG excels at photographs with its lossy compression achieving 10:1 or better ratios while maintaining visual quality. PNG excels at graphics, screenshots, and images requiring transparency with its lossless compression. WebP combines the best of both — lossy and lossless modes, transparency support, and 25–35% better compression than JPEG.

Transparency support is a critical differentiator. JPEG does not support transparency at all — transparent areas become solid white. PNG supports full 8-bit alpha transparency (256 levels of opacity per pixel), enabling smooth edges and semi-transparent effects. WebP also supports alpha transparency. GIF supports only 1-bit transparency (fully transparent or fully opaque, nothing in between). SVG, being vector-based, handles transparency natively through its compositing model.

ICO format is specifically designed for website favicons and Windows application icons. An ICO file can contain multiple image sizes (16×16, 32×32, 48×48, 256×256) in a single file, allowing the operating system or browser to display the most appropriate size. Modern browsers also accept PNG favicons, but ICO remains the most universally compatible choice. Converting PNG to ICO is one of the most common image conversion tasks for web developers.

BMP and TIFF are older formats still encountered in specific workflows. BMP (Bitmap) is Windows' native uncompressed format, sometimes used in legacy enterprise applications. TIFF supports multiple pages, layers, and high bit-depth color, making it the standard in print production and medical imaging. HEIC is Apple's modern format using HEVC compression — iPhones save photos in HEIC by default since iOS 11, but support outside Apple's ecosystem remains limited, making HEIC-to-JPG conversion a frequent necessity.

How to Convert Images Between Any Format

Select your image

Upload JPG, PNG, WebP, BMP, TIFF, HEIC, SVG, ICO, or GIF files. The tool detects the source format automatically and displays resolution and file size.

Pick the target format

Choose your desired output format. Each option shows which features it supports (transparency, lossless compression, animation) to help you decide.

Adjust format-specific settings

For JPEG: set quality (1–100). For PNG: choose compression level. For WebP: select lossy or lossless mode. For ICO: choose which icon sizes to include.

Convert and save

The conversion runs instantly in your browser. Download the converted file. Color profiles and image orientation are preserved through the conversion.

Key Features

Universal Format Support

Convert between 12+ image formats including JPG, PNG, WebP, BMP, TIFF, HEIC, SVG, ICO, GIF, and AVIF.

Transparency Handling

Intelligently handles transparency when converting between formats. Transparent PNGs get a white background when converting to JPEG, and retain transparency when converting to WebP.

Color Profile Preservation

Maintains color accuracy by preserving ICC color profiles through conversions when supported by the target format.

Instant Browser Processing

Conversions happen in your browser using Canvas API and WebAssembly — no server uploads, no queue wait times, instant results.

Frequently Asked Questions

Which format produces the smallest file for photographs?

WebP lossy produces the smallest file for photographs at equivalent quality — approximately 25–35% smaller than JPEG and 80–90% smaller than PNG. If WebP compatibility is not sufficient for your audience, JPEG at quality 80 is the best universal choice.

When should I use PNG instead of JPEG?

Use PNG for images that need transparency, screenshots with text, logos, icons, diagrams, and any image with sharp edges or solid colors. PNG's lossless compression preserves sharp edges perfectly, while JPEG's lossy compression causes visible blurring around text and edges.

Why are my iPhone photos in HEIC format?

Since iOS 11 (2017), iPhones save photos in HEIC format by default because it produces files approximately 50% smaller than JPEG at equivalent quality. However, HEIC has limited support outside Apple devices. You can change this in Settings > Camera > Formats > "Most Compatible" to save as JPEG, or convert individual HEIC files using this tool.

How do I convert a PNG logo to ICO for my website favicon?

Upload your PNG logo and select ICO as the output format. For favicons, ensure your source image is square (1:1 aspect ratio). The tool generates an ICO file containing multiple standard sizes (16×16, 32×32, 48×48). Place the resulting favicon.ico file in your website's root directory.
