Image Converter

What is this tool?

Image Converter is a client-side tool that reads an image — including HEIC/HEIF photos from an iPhone — and re-encodes it as PNG, JPEG, WebP, GIF, BMP, TIFF, ICO, EPS, PDF or SVG (AVIF and HEIC output depend on your browser), using your browser's own image processing. It's designed for quick conversions without installing desktop software.

When to use it

  • Converting a PNG with transparency into a JPG for smaller file size
  • Turning a photo into WebP for faster-loading web pages
  • Converting an old BMP or GIF file into a modern format
  • Preparing an image in the specific format a website or platform requires
  • Opening an iPhone HEIC photo as a JPEG or PNG that any app can read

How to use it

  1. 1Open the Image Converter and upload your image.
  2. 2Choose the target format (PNG, JPEG, WebP, GIF, BMP, TIFF, ICO, EPS, PDF or SVG; AVIF and HEIC where your browser can encode them).
  3. 3Adjust quality settings if the target format supports them.
  4. 4Preview the converted image.
  5. 5Download the file in its new format.

Frequently asked questions

Can I convert a PNG with a transparent background to JPG?

Yes, though JPG doesn't support transparency, so the transparent areas will be filled with a background color during conversion.

Does converting to WebP or AVIF reduce quality?

These are typically more efficient formats, and quality depends on the compression setting you choose; the tool lets you preview the result before downloading. AVIF encoding depends on your browser — where it can't, the tool saves a PNG instead and says so.

Can I convert an animated GIF?

Not as an animation. The tool converts a single frame, so an animated GIF is converted as its first frame, and GIF output isn't animated either.

Is my image uploaded anywhere during conversion?

No, all conversion happens locally in your browser using its built-in image processing capabilities.

What formats are supported?

Output: PNG, JPEG, WebP, GIF, BMP, TIFF, ICO, EPS, PDF and SVG, plus AVIF and HEIC in browsers that can encode them (otherwise a PNG is saved). Input: any image your browser can open, including HEIC/HEIF photos from an iPhone. SVG output wraps your image as raster data inside an SVG file — it does not trace the picture into vector shapes.
