How it works

ConvertCabin draws your image onto a canvas inside this browser tab and re-encodes it in the new format — entirely on your device. The file is never uploaded, so there's no queue, no daily cap, and no account.

Most converters that rank for these searches upload your image to a server first. Because ConvertCabin does the work locally, it stays genuinely free, unlimited and private — and keeps working offline once the page has loaded.

Choosing a format

PNG is lossless with transparency — best for graphics and screenshots. JPG is the smallest, most compatible choice for photos. WebP is a modern web format that beats both on size. AVIF is the newest and smallest, but support for saving it varies by browser.

Frequently asked questions

Which format should I choose?
PNG for graphics or anything needing transparency, JPG for the most compatible photos, WebP for smaller web images, and AVIF when you want the smallest file and your browser supports saving it.
Why didn’t AVIF (or WebP) export work?
Saving AVIF and WebP depends on your browser. Recent Chrome and Edge handle them well; if a format fails, try PNG or JPG, or update your browser.
Is anything uploaded?
No. Every conversion happens on your device, so your images never leave your machine.
