PRODUCT / PDF TOOLBOX
A better next step
for every PDF.
Assemble documents, prepare searchable archives, fill forms, and extract useful data. Each operation has a dedicated endpoint and an implementation guide.
PDF redaction API
Send a PDF URL, base64 file, or private uploaded fileId. Text matching uses the existing text layer; choose page areas for scans. Output is image-only and loses selectable text, forms, links, and signatures. Every requested text must match or the job fails. Review the rendered result before sharing.
EXPLORE THE OPERATIONSearchable PDF OCR API
English language data is installed by default. Supported native uploads accept up to 100 MiB, with a maximum of 500 PDF pages and a 32 MiB returned-output limit.
EXPLORE THE OPERATIONPDF/A conversion API
Validate the generated file against your archival requirements. Supported native uploads accept up to 100 MiB and 500 PDF pages, subject to output limits.
EXPLORE THE OPERATIONMerge PDFs
Merge between 2 and 20 PDF inputs from URLs or base64 file payloads.
EXPLORE THE OPERATIONExtract PDF pages
Select pages using string ranges like 1-3,5 or explicit integer arrays.
EXPLORE THE OPERATIONProtect PDFs
Set userPassword and optional ownerPassword. Output remains standard PDF.
EXPLORE THE OPERATIONRaster PDF pages
Default is page 1. Multiple pages return a zip of images.
EXPLORE THE OPERATIONStamp a PDF
Exactly one of text or image. Position defaults to center.
EXPLORE THE OPERATIONImages to PDF
Each image becomes one page. 1–20 PNG/JPEG inputs.
EXPLORE THE OPERATIONFill PDF forms
POST /v1/pdf/form/fields to inspect, then POST /v1/pdf/form/fill. Flatten is on by default.
EXPLORE THE OPERATIONExtract PDF data
PDF + optional JSON Schema → structured JSON. Omit schema for Markdown. Failed extracts are not billed.
EXPLORE THE OPERATIONMORE IN THE TOOLBOX
Finish the document workflow.
PDF redaction
Remove literal text or page areas and return an image-only PDF without original text objects, attachments, or metadata.
Assemble & arrange pages
Merge, extract, rotate, delete, crop, and resize pages. Add bookmarks or combine images into a PDF.
Forms & protection
Inspect AcroForm fields, fill and flatten them, add watermarks, or password-protect and unlock documents.
Compress & repair
Optimize PDF structure, choose a compression preset, and normalize recoverable files. Lossy compression can alter forms, annotations, and tags.
Preview & package
Rasterize PDF pages into images and bundle files into a ZIP for the final handoff.
Searchable OCR
Add a text layer to scanned PDFs while retaining existing text. English language data is installed by default.
Structured data extraction
Extract JSON fields using your schema, or get Markdown without a schema. All selected pages are processed within documented limits.
Text & metadata
Read the existing text layer and inspect page count and document metadata. Text extraction itself does not add OCR.
Embedded assets
Extract embedded images or attachments into a ZIP. Embedded-image extraction differs from rendering whole pages.
Basic tools use per-operation pricing; native processing and AI extraction use their applicable rates. See pricing. Input, page, and output limits depend on the endpoint.
