Frequently asked
Are my images uploaded anywhere?+
No. Conversion runs entirely inside your browser using the Canvas API. Your files never touch our servers.
Which formats are supported?+
PNG, JPG, WebP, and AVIF as both input and output. HEIC/HEIF (iPhone photos), GIF, and BMP are accepted as input — they're decoded and converted to one of the four output formats. PSD, TIFF, ICO, and SVG aren't supported yet.
How does HEIC conversion work?+
HEIC (the format iPhones use) isn't supported natively by browsers, so the first time you convert one, the page lazy-loads a small WebAssembly decoder. After that, everything runs locally — your photos never leave your device.
Why is the AVIF output sometimes missing?+
AVIF encoding is supported in Chrome and Edge but not in current Safari or Firefox versions. If your browser can't encode AVIF, you'll see an error — try WebP, which is supported everywhere.
What's the difference between quality 60 and 95?+
Quality controls how aggressively the image is compressed (JPG, WebP, AVIF only). Lower values mean smaller files but more visible artifacts. 80–90% is a good default for photos.
Is there a file-size limit?+
Each file can be up to 50 MB. The browser holds the file in memory while converting, so very large images may be slow on low-RAM devices.
