Why Use This Image Converter?

  • Completely private – all processing happens inside your browser using the HTML5 Canvas API. Your photos are never sent to any server.
  • Batch conversion – upload dozens of images at once and convert them all in one go.
  • Multiple output formats – save as WebP for the smallest file sizes, JPEG for universal compatibility, or PNG for lossless quality.
  • HEIC support – iPhone HEIC/HEIF photos are automatically decoded before conversion.
  • Per-image settings – each photo can have its own format and quality, or lock a setting across the whole batch with Apply to all.
  • Free & unlimited – no sign-up, no watermarks, no limits.

Choosing the Right Output Format

Not sure which format to pick? Here's a quick guide:

  • WebP – best overall file size. Typically 25–35% smaller than JPEG at the same visual quality. Supported by all modern browsers and most social platforms. Ideal for web use.
  • JPEG – universally compatible with every device, app, and platform. Great for photos with lots of colour gradients. Quality 75–85 is a good sweet spot between size and clarity.
  • PNG – lossless encoding. Larger files than JPEG/WebP but pixel-perfect — ideal for screenshots, logos, and images with flat colours or transparency.

Frequently Asked Questions

Yes, 100% free with no usage limits. No account or payment information is required.
No. All conversion happens entirely inside your browser. Your images are never sent anywhere, so your privacy is fully protected.
There is no hard limit. You can add as many photos as you like and convert them all in a single session. Very large batches may take a few moments depending on your device's processing power.
Yes. HEIC and HEIF files are automatically decoded in your browser before conversion. A progress indicator is shown during the decoding step.
For most photos, a quality of 80–90 gives an excellent balance between visual sharpness and file size. Use higher values (90–100) when you need the best possible quality, and lower values (50–75) to minimise file size. The quality slider is disabled for PNG because PNG uses lossless encoding.
WebP typically produces files 25–35% smaller than equivalent JPEG files at the same visual quality. All modern browsers support WebP, making it ideal for websites where page load speed matters.
Yes. Tick the Apply to all checkbox next to the format dropdown or the quality slider and any change you make will be applied to every image in the batch instantly.
