How it works
Three quiet steps.
- 01
Drop your files
Drag images into the converter or pick them from your device. Any number, any size.
- 02
Choose a format
Pick a target format, adjust quality, resize if needed. Keep the aspect ratio locked.
- 03
Convert & download
Everything happens locally. Download images individually or as a ZIP.
Privacy
Your files never leave the browser.
FormatFlip has no server. Images are decoded by your browser, redrawn on a local canvas, and re-encoded into the format you chose — all in memory. We can't see them because nothing is sent anywhere.
- No uploads. Not even for analytics.
- No account, no email, no cookies.
- Works offline once the page is loaded.
- Close the tab and every trace is gone.
FAQ
Good to know.
Are my images uploaded anywhere?+
No. Conversion happens entirely in your browser using the Canvas API. Files never touch a server.
Which formats are supported?+
PNG, JPEG, WebP, AVIF, BMP and GIF as output. Any image your browser can decode works as input.
Why is AVIF sometimes disabled?+
AVIF encoding depends on the browser. FormatFlip detects support automatically and hides the option when it isn't available.
Is there a file size limit?+
Only your device's memory. Very large images may take a moment to decode and redraw.
Does resizing keep quality?+
We use the browser's high-quality image smoothing when resizing. For photographic content, WebP or AVIF give the best size-to-quality ratio.
Can I convert GIFs while keeping animation?+
FormatFlip converts the first frame — Canvas doesn't preserve animation. For animated output, use a specialised encoder.
