What does Convert Image do?

Convert Image changes the format of your pictures: PNG to JPG, JPG to PNG, WebP to JPG, HEIC to JPG, GIF or BMP to PNG, and any of them to modern WebP or AVIF. Drop as many files as you like, choose the target format once and download the results individually or in a single ZIP.

Which format should I choose?

  • JPG is the universal format for photographs: every device, program and website opens it. It does not support transparency, so transparent areas are filled with the background colour you pick (white by default).
  • PNG is lossless and supports transparency. Use it for logos, screenshots, diagrams and images with text. For photos it produces much larger files than JPG.
  • WebP combines small files with transparency and is supported by all current browsers. It is the best default for websites.
  • AVIF is the most efficient format today, often half the size of JPG, but creating it requires a recent Chrome, Edge or Firefox. The tool warns you if your browser cannot write it.

For JPG, WebP and AVIF you can set the quality; 85–90% keeps photos virtually identical to the original. Animated GIFs are converted using their first frame.

About HEIC photos from iPhone

iPhones save photos as HEIC by default. Safari can decode HEIC, so on a Mac or iPhone you can convert those photos to JPG directly here. Chrome and Firefox on Windows or Android cannot open HEIC yet; in that case the tool tells you so, and you can set your iPhone to share photos as JPG (Settings → Camera → Formats → Most Compatible).

Private by design

The conversion is performed by your browser's own image decoders and encoders. Your files are never uploaded and the results are created on your device, which is ideal for personal photos and client work.

Frequently asked questions

Does converting improve quality?

No. Converting a low-quality JPG to PNG makes the file bigger but cannot restore lost detail.

Are metadata and colour profiles kept?

The pixels are re-encoded, so EXIF data is dropped. Colours are converted to standard sRGB, which is what screens and the web expect.
