PDF to WebP API Overview
Convert PDF documents to modern WebP images to reduce file sizes while preserving visual fidelity. Handle password‑protected files and restrict processing to specific page ranges. Control output with image resolution (DPI), scale proportions with explicit width/height to match UI or storage constraints, and apply anti‑aliasing for crisp rendering. Choose lossless or lossy compression and adjust quality to balance clarity and size, and optionally map a color to transparency for predictable results. Ideal for web and mobile delivery, batch optimization, and CDN pipelines where small, faithful images are required.

File
File Supported formats: .pdfFile to be converted. Value can be URL or file content.
Password
StringSets the password to open protected documents.
PageRange
String Default: 1-2000Set page range. Example 1-10 or 1,2,5.
ImageResolution
Integer Default: 200Set output image resolution in dpi.
Range: 10 .. 800ScaleProportions
Bool Default: TrueIf set to true, the barcode will be generated using recommended proportions based on the larger dimension.
ImageHeight
IntegerImage height in pixels.
Range: 10 .. 10000ImageWidth
IntegerImage width in pixels.
Range: 10 .. 10000ImageAntialiasing
Integer Default: 8Control the use of text and graphics subsample antialiasing. The subsampling box size should be 8 bits for optimum text antialiasing, but smaller values can be used for faster rendering.
Range: 0 .. 8Rotate
IntegerRotate image by angle.
Range: -360 .. 360TransparentColor
ColorAdd alpha channel to image, setting pixels matching color to transparent. Values accepted are RGBA, CMYK hex string, color name or RGB format like this 255,255,255 (RED=255, GREEN=255, BLUE=255) or 255,255,255,150 with alpha chanel.
ImageQuality
Integer Default: 75Set output image quality.
Range: 10 .. 100StoreFile
Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
