How to convert an image

  1. 1

    Choose your image

    Drag a JPG, PNG, WebP or AVIF file onto the drop area, or browse for it.

  2. 2

    Pick an output format

    Choose JPG, PNG, WebP or AVIF, then set a quality level and optionally resize.

  3. 3

    Convert and download

    Press Convert image. The result appears with its real size and dimensions, ready to download.

Which format should you pick?

  • JPG — photographs, and anywhere maximum compatibility matters. No transparency.
  • PNG — screenshots, logos, line art and anything needing a transparent background. Lossless, so files are larger.
  • WebP — a good default for the web. Typically 25–35% smaller than JPG at comparable quality, and it supports transparency.
  • AVIF — the smallest of the four at a given quality, but the slowest to encode and the least widely supported by desktop software.

What happens to the original

Nothing. Your file is read into memory, decoded, re-encoded and handed back to you as a download. The original on your disk is untouched, and no copy is kept anywhere.

Because the output is re-encoded from decoded pixels, camera metadata such as EXIF and GPS coordinates is not carried across. That is a deliberate privacy default.

Frequently asked questions

Are my images uploaded to a server?
No. The conversion runs in your browser using WebAssembly and canvas APIs, so the image data never leaves your device. There is no upload endpoint in this application at all — you can watch the network tab while you convert.
Is there a file size or daily limit?
No. There is no quota, because there is no server doing the work — the limit is your device's memory. Very large images may take a few seconds on an older phone.
Will there be a watermark?
No. The output is exactly the image you converted, with no marks added.
Do I need an account?
No. There is no signup, no email, and no login anywhere in this tool.
Which formats can I convert between?
JPG, PNG, WebP and AVIF, in any combination. The tool also reads formats your browser can decode, such as GIF and BMP, and converts them into one of those four.
