Convert Image Format using n8n action

PDF4me Convert Image Format transforms images between different file formats through n8n automation workflows. Process images via n8n triggers, binary data, base64 strings, or public URLs to convert between JPG, PNG, GIF, BMP, WEBP, and TIFF formats with preserved image quality, intelligent color space handling, transparency support, and format-specific optimizations. This solution is ideal for web optimization, format standardization, compatibility requirements, social media preparation, print workflows, and automated format conversion that require reliable image transformation with quality preservation and seamless integration.

	GIF	Yes (One Required)	GIF Format - Graphics Interchange Format with limited colors, ideal for simple graphics and animations
	BMP	Yes (One Required)	BMP Format - Bitmap format with uncompressed data, ideal for high-quality archival purposes
	WEBP	Yes (One Required)	WEBP Format - Modern web image format with superior compression and quality, ideal for web optimization
	TIFF	Yes (One Required)	TIFF Format - Tagged Image File Format with lossless compression, ideal for professional printing and archival
Output File Name	String	Yes	PDF4me converted image output filename - Specify the name for the generated converted image file with proper extension (.jpg, .png, .gif, .bmp, .webp, .tiff). PDF4me ensures unique naming and validates file format compliance
Binary Data Output Name	String	Yes	PDF4me binary data mapping - Define the variable name for accessing the generated converted image binary data in your n8n workflow. This binary data can be used as input data in subsequent actions within your workflow
