Supported Image Formats
Transfonic's AI image upscaler works with all major image formats — no pre-conversion needed:
JPEG, JPG — Most common photo format, perfect for upscaling product and portrait photos
PNG — Lossless format with transparency support, great for logos and illustrations
WebP — Modern web format, upscale without losing the compression benefits
BMP, TIFF, TIF — High-quality formats used in professional photography and print
GIF — Supported for static image upscaling

After upscaling, you can also convert your image to WebP format to reduce file size while keeping the enhanced quality — perfect for faster website loading.
Why Use Transfonic AI Image Upscaler?
Transfonic features advanced AI technology to analyze your image pixel by pixel and intelligently relayer detail on enlargement — as opposed to the regular upscalers that only stretch pixels and create blurs. The difference is plain: Edges remain sharp, textures look natural, and colors are accurate even after 5x enlargement.
It is Totally Free to use, with no file limits, no watermarks & no premium plan. It works completely in your browser on any device — Windows, Mac, Android, or iOS — and requires no installation. All images uploaded are processed over 256-bit SSL encryption and deleted from our servers as soon as the conversion is completed. Photos are never saved, shared, or accessed by anyone.
If you need to make further adjustments after upscaling, you can convert your image to another format like PNG, WebP, or TIFF for the best compatibility across different platforms and use cases.
