How to use this tool

  1. Add files or drag them into the workspace. Nothing is uploaded; processing happens in your browser.
  2. Choose an output format — and for images and audio, a quality level — for each file. Nothing is preselected on this page.
  3. Start the conversion, then download individual results or the completed batch.

Quality and format notes

PNG is the safe, lossless choice for screenshots, line art and images needing transparency. Pick a conversion below to preselect its formats: to WebP or AVIF when web performance matters, to JPG when a form only accepts photos, or into PNG from WebP, JPG, HEIC, SVG or PDF pages.

Lossless PNG files are usually larger than lossy outputs. If a converted PNG must stay small, run it through the image compressor or choose JPG/WebP instead.

Frequently asked questions

Is PNG lossless?

Yes. PNG stores every pixel exactly, which is why it is preferred for screenshots, diagrams and any image that must not degrade — and why files are larger than lossy formats.

When should I not use PNG?

For photographs destined for sharing or the web, JPG or WebP give far smaller files with no visible difference. PNG shines on sharp edges, text and transparency.

Are these conversions really free?

Yes. Every tool linked here is free, requires no account, and processes files in your browser rather than on a server.
