Need to edit a photo without uploading it to a server? The Wivrix Image Converter & Compressor is free, works in your browser, and takes seconds to use.
What this tool does
Convert images between PNG, JPEG, WebP and AVIF, resize them with aspect ratio lock, batch convert multiple files and download as ZIP. Free, private, runs entirely in your browser.
Why use Wivrix?
Many online tools ask you to sign up, add a watermark, or upload your files to a server you cannot see. Wivrix is different:
- Private by design — Everything runs in your browser. Your files and input stay on your device — nothing is uploaded to Wivrix.
- Free — no account, no paywall, no file-size tricks
- Fast — open the page and start working
Step-by-step guide
- Upload one or more images (drag & drop or click). PNG, JPG, WebP, GIF, BMP and AVIF are supported.
- Pick an output format: JPEG, PNG, WebP or AVIF .
- Adjust the quality slider for lossy formats. Lower quality means smaller files.
- Optionally resize — the 🔒 lock maintains aspect ratio automatically as you type width or height.
