About Bind

Bind is a free browser utility for one hinge: raster images become a multipage PDF, and PDF pages become raster images. It is not a cloud converter. pdf-lib writes the PDF, pdf.js reads pages, Canvas paints pixels, JSZip packs downloads. Those libraries run in your tab. Close the tab and the documents are gone from Bind, because Bind never held them.

The product is the converter you see on the home page, plus the pages that explain how to use it: how-to, use cases, FAQ, contact. Ads may appear after Google approves the site. Auto-open popups are not part of the design. Advertising partners never receive the files you convert.

In scope

• JPEG, PNG, WebP, BMP, static GIF → PDF with A4 / Letter / Legal / square, margins, Contain / Cover / Stretch.
• PDF → PNG, JPEG or WebP at 1×–3×, all pages or a typed range, single download or ZIP.
• Reorder, iOS Safari, filename sanitization, in-tab memory warnings.

Out of scope

• HEIC decode (use a HEIC converter first).
• Merge, split, compress, OCR, e-sign, form fill, PDF/A, CMYK.
• Accounts, cloud storage, “history of your files”.

Bind is built by Ultimatum. Questions and copyright notices: ultaultimatum@gmail.com. The tool is provided as-is; browser memory is the real limit, not a fake quota.
