Compress PDF in Go

Using our powerful Go API, developers can compress PDF documents to optimize content and output file size. Reducing PDF size occurs by cleaning up unused data and resources. You can also compress images inside PDF to make the output file size even smaller.

The result of content optimization and compression can be saved in the original PDF or any available save format – DOCX, DOC, RTF, HTML and many others. For example, compress PDF and save the output as Word.

Reduce PDF file size in Go

As mentioned, our Go SDK allows you to programmatically reduce PDF size. And now you can try our powerful functionality and evaluate how to compress PDF in Go with the following example:

Upload a file you want to optimize/compress
Run code
Select the target format from the list
import (

config, _ := models.NewConfiguration("config.json")
wordsApi, ctx, _ := api.CreateWordsApi(config)

requestDocument, _ := os.Open("Input.pdf")
requestCompressOptions := models.CompressOptions{
    ImagesQuality: ToInt32Pointer(int32(75)),
    ImagesReduceSizeFactor: ToInt32Pointer(int32(1)),
compressDocumentOnlineOptions := map[string]interface{}{}
compressDocumentRequest := &models.CompressDocumentOnlineRequest{
    Document: requestDocument,
    CompressOptions: &requestCompressOptions,
    Optionals: compressDocumentOnlineOptions,
compressDocument = wordsApi.CompressDocumentOnline(ctx, compressDocumentRequest)

convertDocumentOptions := map[string]interface{}{}
convertDocument := &models.ConvertDocumentRequest{
    Document: compressDocument.Document.Values[0],
    Format: ToStringPointer("pdf"),
    Optionals: convertDocumentOptions,
_, _ = wordsApi.ConvertDocument(ctx, convertDocument)
Run code
Copy Go code to the clipboard
