Konvizi’s “GIF to PNG” tool is free, with no sign-up, no watermark and no file limit. All the processing happens in your browser, on your device: your files are never uploaded to a server, which makes it suitable for personal and confidential documents.
Drag your GIF files into the area above or click “Choose files”. You can add several at once.
Each file is converted to PNG by your browser. Nothing is sent over the internet.
Download your PNG files one by one, or all together with “Download all”.
GIF is an old format, limited to 256 colors, best known for its short looping animations.
For a still image, it is outdated: limited colors, rough transparency. Konvizi extracts the first frame of your GIF.
PNG saves images with no loss of quality and supports transparency. It is the format of screenshots, logos and illustrations with crisp edges.
It is ideal when you want to keep every pixel intact, keep a transparent background, or edit the image later without degrading it.
Your photos stay on your phone or computer: family pictures, photographed ID documents and screenshots are never sent online. The image is redrawn by your browser, so the output file does not carry the original’s EXIF metadata, including GPS location: handy before sharing a photo. And since nothing is uploaded, dozens of images convert in seconds.
Your files never leave your device. No upload, no storage.
No upload and no queue: the conversion starts right away.
As many files as you like, with no imposed size limit.
No sign-up, no watermark, no subscription.

Yes, completely. No sign-up, no watermark, no maximum number of files: you can convert as many files as you like.
No. Everything happens in your browser, on your device. Your files are never sent over the internet: nobody but you can see them.
No. PNG is a lossless format: the image is saved exactly as it is displayed, transparency included. In return, the resulting file is often larger than the original.
Only the first frame of the animation is converted. You get a still image, with its transparency if the GIF had any.
Open your browser’s developer tools (F12 key), go to the “Network” tab and run a conversion: no request carries your file. The site also enforces a security rule (Content-Security-Policy) that forbids the browser from contacting any site other than konvizi.com, and konvizi.com is a static site with no service able to receive files.
Yes. Konvizi works in the browser of your phone or tablet (Safari, Chrome…) just like on a computer, with no app to install. Very large files are processed faster on a computer, which has more memory.
