PDF tools
05 toolsTrueScalers publishes five PDF tools: an editor that changes text and applies signatures, plus 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.
Editing, signing, 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.
PDF editor
Edit text in a PDF, add text boxes, draw or upload a signature, then save a real PDF. Runs entirely in your browser — no upload, no account.

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.
