Image Format Converter
Convert your images between JPEG, PNG, WebP, and HEIC formats instantly. Adjust quality, handle iPhone HEIC photos, and download the result — all without uploading anything.
Image Formats Explained
JPEG
The universal standard for photos. JPEG uses lossy compression to keep file sizes small at the cost of some detail. Supported by every device, browser, and application. Best for photographs where small file size matters more than pixel-perfect accuracy.
PNG
Lossless format that preserves every pixel exactly. Supports transparency (alpha channel), making it ideal for logos, icons, UI screenshots, and design assets. Files are larger than JPEG, especially for photographs.
WebP
Google's modern web format. Delivers 25–34% smaller files than JPEG at equivalent visual quality, and also supports transparency like PNG. Near-universal browser support as of 2024. The best choice for images displayed on websites.
HEIC
Apple's default photo format on iPhones and iPads since iOS 11. HEIC stores photos at roughly half the file size of JPEG with the same visual quality. The catch: limited support outside Apple's ecosystem. Windows and Android often require conversion before you can share or edit HEIC files.
When to Convert Image Formats
Choosing the right format depends on your use case. Converting between formats always involves a trade-off between file size, quality, and compatibility.
- Sharing with Windows or Android users. Convert HEIC photos to JPEG first. Most Windows applications and Android devices cannot open HEIC files natively.
- Uploading images to a website. Convert to WebP for the best balance of quality and file size. Smaller images mean faster page loads and better Core Web Vitals scores.
- Working with design tools. Convert to PNG when you need transparency, or when your tool requires lossless input for editing layers and compositing.
- Maximum compatibility. Use JPEG. Every device, browser, email client, and application handles JPEG without issues. When in doubt, JPEG is the safe choice.
HEIC to JPEG Conversion
Apple introduced HEIC (High Efficiency Image Container) with iOS 11 to reduce photo storage on iPhones. A HEIC photo typically takes up half the space of the same image saved as a JPEG, which is why Apple made it the default.
The problem is that HEIC is an Apple-centric format. Windows 10 and 11 cannot open HEIC files without installing additional codecs — the required HEVC Video Extensions codec costs $0.99 on the Microsoft Store. Most Android phones, web services, and image editors either ignore HEIC or return an error. Many social media platforms and stock photo sites also reject HEIC uploads.
Converting to JPEG solves all of these compatibility issues. This tool handles the HEIC decoding entirely in your browser — no software to install, no file upload, no cloud service required.
Common Use Cases
iPhone Users
Convert HEIC photos to JPEG before emailing to friends, submitting to online forms, or uploading to services that don't support HEIC. No app installation needed.
Web Developers
Convert images to WebP to reduce page weight and improve Lighthouse scores. Smaller images load faster, reducing bounce rates and improving user experience.
Designers
Convert between PNG and JPEG depending on what your deliverable requires. Export transparent assets as PNG, and compress opaque photos to JPEG or WebP for handoff.
Cross-Platform Sharing
Convert to JPEG or PNG before sharing images across different operating systems, devices, and applications. JPEG in particular opens everywhere without any additional software.
