Images are processed locally when browser capabilities and current limits allow. Otherwise, the tool uses server processing when available. Supports JPG, WebP, GIF, SVG, AVIF, BMP, HEIC/HEIF, and PNG input. Batch conversion and transparency controls are available within current limits; animated inputs become still PNG files.
Why Use FastImageTools
Local-First Processing
Images are converted in your browser when supported. Files outside local capabilities or limits use server processing when available.
Instant Results
Review your settings and estimated file size before converting. No signup or email is required.

No signup or watermarks. Available file and batch limits depend on the current plan and processing route.

Local processing can preserve detected alpha or flatten it to a chosen background. Advanced color settings depend on the processing route.

Supported Input Formats
JPG / JPEG
Photographs and web images. PNG encoding does not restore detail already lost in a lossy source or add transparency.
WebP
Modern web format with lossy or lossless compression. Convert to PNG for broader compatibility.
GIF
Simple animations and graphics. Only the first frame of animated GIFs is converted.
SVG
Scalable vector graphics. SVG input is rasterized using its decoded dimensions.
AVIF
Modern compressed images. Convert to PNG when a PNG workflow or decoder compatibility is needed.
BMP
Bitmap images. PNG uses lossless encoding, but output size can vary.
