How does image format conversion work?

When you convert an image, ConvertIMG reads the pixel data from your original file and re-encodes it in the new format. For lossy formats like JPG and WebP, you can adjust the quality level to control the balance between file size and image quality. For lossless formats like PNG, every pixel is preserved exactly. The conversion process also handles metadata. You can choose to keep your EXIF data (camera info, GPS coordinates) or strip it for privacy. ConvertIMG handles all the technical details automatically — just upload, choose your format, and download.

When should you use which format?

Choosing the right format depends on your use case: For photos and sharing: JPG is the universal choice. Nearly every device and platform supports it. For websites: WebP offers the best balance of quality and file size. It loads faster than JPG or PNG. For graphics and transparency: PNG preserves every detail and supports transparent backgrounds. For maximum compatibility: JPG works everywhere. Convert HEIC, AVIF, or WebP to JPG when you need broad support. For smallest file size: WebP or AVIF provide the best compression with good quality.

Why would you want to convert image formats?

Different platforms and devices require different image formats. For example, iPhones save photos as HEIC files, but many websites, apps, and email services don't support HEIC. Converting HEIC to JPG or PNG makes your photos compatible with everything. Similarly, converting PNG images to WebP can dramatically reduce file sizes for faster web loading.

Format conversion is also essential for professional work. Designers and photographers often need to deliver images in specific formats. Print projects may require TIFF or PNG, while web projects benefit from WebP or optimized JPG. With ConvertIMG, switching between formats takes just a few clicks.
