About This Tool
Unified image conversion endpoint. Fetches a remote image and streams back a converted file in the target format. Supports PNG, JPEG, WebP, GIF, BMP, TIFF, and AVIF where available.
For inline base64 workflows, use [Image Convert](/convert/tools/image-convert).
Why Use This Tool
- WebP delivery — Convert PNGs/JPEGs to WebP for smaller on-the-wire payloads
- Legacy compatibility — Convert modern formats back to PNG/JPEG for older clients
- Pipeline integration — One-URL image format conversion in shell scripts
- Content migration — Normalize mixed image libraries
Frequently Asked Questions
What source formats are supported?
PNG, JPEG, WebP, GIF, BMP, TIFF, HEIC, and most raster formats supported by Pillow.
Is transparency preserved?
When both source and target support it. Converting to JPEG flattens transparency to the configured background (white by default).
Can I resize during conversion?
Not via this endpoint — use the image toolkit's resize endpoints before conversion.
