PDF tools
04 toolsTrueScalers publishes four PDF tools: merge, split, compress, and image-to-PDF conversion. Every one runs on the pdf-lib library inside the browser, so a contract, payslip or passport scan is parsed and rebuilt on the visitor’s own device and never uploaded to a server, which is what separates these from the upload-based PDF sites.
Merging, splitting, compressing and building PDFs. Unlike every upload-based PDF site, your document is opened and rewritten inside this page — it never reaches a server, so there is nothing to leak and nothing to delete.
Merge PDF
Combine two or more PDF files into one document in your browser. No upload, no account, no watermark and no page limit.

Split PDF
Extract pages from a PDF, split it into fixed-size parts, or separate every page into its own file. Runs in your browser.

Compress PDF
Shrink a PDF by lowering render resolution and image quality. Control DPI and JPEG quality directly. Nothing is uploaded.

Images to PDF
Turn JPG, PNG and WebP images into a single PDF. Choose A4, Letter or fit-to-image page size. Runs entirely in your browser.
