Choosing the Right Image Format
The major formats explained
Each image format was designed for a different job. PNG is lossless and supports transparency, making it ideal for logos, icons, and screenshots. JPG is built for photographs and offers small files at the cost of transparency. WebP and AVIF are modern formats that compress far better than both, while HEIC is the high-efficiency format used by recent iPhones.
Converting between them lets you use the best tool for each situation — for example, turning a heavy PNG photo into a compact WebP for the web, or converting an iPhone HEIC into a universally compatible JPG.
When to convert and why
Convert to WebP or AVIF when you want the smallest possible files for a fast-loading website. Convert to JPG when you need something that opens everywhere, from old software to email clients. Convert to PNG when you need crisp edges or transparency, such as a logo placed over a colored background.
HEIC files are a common pain point because many apps and websites cannot open them; converting HEIC to JPG or PNG solves compatibility issues in one step.
Quality, transparency, and metadata
Converting from a lossy format (like JPG) to a lossless one (like PNG) will not restore detail that was already discarded — it only changes the container. Converting the other way, or between lossy formats, re-encodes the image, so choosing a sensible quality matters. Picovert preserves transparency when both formats support it and drops it gracefully when the target does not.
Every conversion runs locally in your browser. Your images are never uploaded, which keeps private photos and sensitive documents entirely on your device.
