For photographs on a website, WebP gives the best size-to-quality ratio and is supported by every modern browser. AVIF compresses even harder but encodes more slowly. Use PNG when you need transparency or crisp screenshots and logos. Stick with JPG when a system or printer specifically demands it — it is the most universally accepted.
Yes, drop up to 20 files and they convert in parallel, four at a time, so a batch finishes quickly without overloading the engine. Each file appears in the list with its own status, and you can download them individually or grab everything as a single ZIP once the batch completes.
PNG, WebP and AVIF all support transparency, so converting between them keeps it intact. JPG has no alpha channel, so any transparent area becomes solid white. If your image has a see-through background you want to keep, avoid JPG and choose WebP for the best combination of transparency and small file size.
Yes, Image Format Converter is completely free. No signup, no account, and no watermark on outputs. A Pro tier is available for 100 AI ops/day and larger file sizes.
Image Format Converter uploads your file over an encrypted connection to our own processing server, converts it, and returns the result. The file is deleted immediately after processing and is never used for anything else. It is not sent to any third party, and we keep no copies.

This free online image converter converts images between JPEG, PNG, WebP, and AVIF — including HEIC from iPhone. Files are processed on our secure engine and deleted immediately after.
Which format should I choose? Use WebP for web images — 25–35% smaller than JPEG at the same quality. Use AVIF for the best compression — up to 50% smaller than JPEG. Use PNG for lossless quality or transparency. Use JPEG for maximum compatibility.
Batch conversion: Convert up to 20 images at once and download them as a single ZIP file — great for bulk converting photo libraries or web assets.
Quality & privacy: Conversion runs on the sharp / libvips engine for best-in-class encode quality. Uploads are sent over an encrypted connection and deleted immediately — never stored, no account, no watermarks.
