Example

Example: two iPhone HEIC photos and a WebP turned into JPGs for an insurance claim

A leak from the flat upstairs stained the ceiling and ruined a floor lamp. The insurer’s online claim form takes JPG or PNG only. Tom has two iPhone photos of the ceiling (HEIC, 4032 × 3024) and the lamp’s picture saved from the shop’s website (WebP, 1000 × 1000). He adds all three, Convert to: JPG, Quality left at 0.9.

  1. The first HEIC loads a small decoder, because browsers cannot read HEIC by themselves; the WebP is read by the browser.
  2. Each picture is drawn again at its own size and saved as JPG at quality 0.9: IMG_5521.HEIC becomes IMG_5521.jpg, still 4032 × 3024.
  3. Three files is exactly one run on the free plan. Download them one by one or as a ZIP and attach them to the form.

Three JPGs the form accepts, with the same names and pixels. They carry no EXIF data, so the date and place the photos were taken are not in them: if the insurer asks when the damage was photographed, keep the original HEIC files.

How it works

  1. Drop images onto the box or pick them from your device. HEIC, HEIF, WebP, AVIF, SVG, PNG, JPG, GIF and BMP are accepted, and you can mix formats in one run.
  2. Choose the target format. JPG for photos and maximum compatibility, PNG to keep transparency, WebP for the smallest files on the web. AVIF is offered only in a browser that can write it.
  3. Adjust the quality slider for JPG and WebP. 0.9 is near-lossless; 0.75 is a good balance for web use. PNG ignores the slider.
  4. Press Convert images and download the files individually or as a ZIP.

Frequently asked questions

Are my images uploaded?
No. Decoding and encoding happen in a Web Worker in your browser. The files stay on your device, and the tool works with the network off.
How are HEIC files from an iPhone handled?
Browsers cannot decode HEIC natively, so a small WebAssembly decoder is loaded the first time you convert one. After that, conversion is fully local and works offline.
Why is there no AVIF choice in my browser?
The pictures are written by the browser’s own encoder, and Chrome, Edge, Firefox and Safari currently have none for AVIF: asked for one, Chrome hands back a PNG. So the AVIF choice only appears in a browser that can write it. Reading AVIF works in Chrome, Firefox and Safari 16 or later, so AVIF to JPG or PNG works there; for small web pictures, choose WebP.
What happens to transparency?
PNG and WebP keep transparent areas. JPG has no alpha channel, so transparent pixels are filled with white.
Do converted pictures keep their date and location?
No. Each picture is drawn on a canvas and saved fresh, which writes no EXIF: the camera, the date taken and any GPS position are left behind. That is handy before posting a photo, but keep the original when the date it was taken matters.
Does converting a JPG to PNG improve the quality?
No. PNG stores the pixels exactly as they are, so a JPG turned into PNG keeps whatever the JPG had already lost, and the file usually gets several times bigger. Convert to PNG for transparency or for a program that asks for PNG, not for quality.
What are the free limits?
The free plan allows 3 files per run, 20 MB per file and 5 runs per day. Pro removes these limits.
