## What it does

Drop in any images your browser can read — PNG, JPEG, WebP, GIF, BMP, SVG, AVIF — pick a target format, and download the results one by one or as a zip. The quality slider re-converts on the fly and shows the new file size immediately, so you can tune the size/quality trade-off until it's right instead of guessing.

Everything runs locally in a Web Worker: no upload, no queue, no server ever sees your files. Re-encoding also strips EXIF metadata (GPS position, camera model, timestamps), which makes this a quick way to clean images before publishing them.

## Limits

Does not edit, crop or resize beyond the format change, and does not convert RAW camera files or PDF pages.

## FAQ

### Are my images uploaded anywhere?

No. Conversion happens inside your browser using the canvas API and a Web Worker — files never leave your device. There is no upload step, no queue and no file size limit beyond your machine's memory.

### Is EXIF metadata kept in the converted image?

No — and that's a feature. Re-encoding through the canvas strips all metadata: GPS location, camera model, timestamps and color profiles. The output contains pixels only, which is usually what you want before sharing an image publicly.

### Can I convert many images at once?

Yes. Drop or paste any number of files; each is converted in the background with its own progress and download button, and you can grab everything at once as a .zip archive.

### Will converting lower my image quality?

It depends on the target. The converter always decodes to raw pixels and re-encodes, whichever formats are involved, which is also how metadata gets stripped. For lossless targets (PNG, and GIF within its 256-color limit) the pixels stay identical to what was decoded; for JPEG, WebP and AVIF the quality slider controls the trade-off, and converting a file that is already lossy adds one more generation of loss.
