A free collection of tools for batch converting and processing PDF files · completely free · 100% local processing, nothing uploaded
Merge a batch of images into a single PDF, one page per image — crop, compress, or watermark them first if you like.
Turn every page of a PDF into an image — the resulting images can be cropped, compressed, or watermarked like any other photo.
Combine multiple PDF files into one, in whatever order you choose — a purely structural operation, nothing re-rendered, quality identical to the originals.
Split a PDF by page range into multiple files, or split every page into its own file with one click — same structural operation, no quality impact.
Shrink a PDF's file size for easier sending and uploading — re-encodes embedded JPEG images, never touches the text layer, so text stays selectable and searchable.
Add a text watermark (CONFIDENTIAL, DRAFT, your company name) to every page, English and Chinese supported, with adjustable opacity, angle, and tiled or centered placement.
Rotate every page by 90°/180°/270° to fix a document scanned or photographed sideways — same structural operation, no quality impact.
Extract plain text from a PDF and export as a .txt file — use this first for any PDF: pages with a real text layer come back instantly and fully accurate, and pages without one automatically fall back to OCR, no need to figure out which is which.
Recognize text in photos or screenshots, English and Chinese supported — this one's for images. Got a PDF instead? Use PDF to Text on the left, which already handles scanned PDFs automatically; this tool runs every PDF page through OCR regardless, which is slower and less accurate than direct extraction.
