Every one of these runs in your browser, on your device. There are no accounts, no file size limits, no watermarks, no queue and no paid tier — because there is no server doing the work and therefore nothing to charge for. Open your network tab and watch while you use any of them.
Privacy score out of 100, a plain-English list of what your file reveals — location, names, tracked changes, hidden sheets — and a verified clean copy. Photos, HEIC, PDFs, Office files and ZIP archives.
Check a file →OpenCombine PDFs and images into one document. JPG, PNG and HEIC photographs become pages, reorder them as you like, and nothing is re-rendered or uploaded.
Merge PDF files →OpenAdd text, drop in an image or signature, then rotate, reorder or delete pages. Existing text stays selectable.
Edit a PDF →OpenReduce PDF file size without blurring the text. Images are re-encoded at a quality you choose; text and vector graphics stay untouched.
Compress a PDF →OpenExtract any pages or ranges into a new document — type 1,4,7-12. Free, no signup, no watermark.
Split a PDF →OpenJPG, PNG and HEIC into a PDF. Photos are turned upright automatically, copied in without re-compression, and can be rotated by hand.
Convert JPG to PDF →OpenRecover the photographs embedded in a document at their original quality, exactly as they went in.
Extract images →OpenBatch compress JPG, PNG, WebP and HEIC. Choose the quality and size, and see before and after on every file.
Compress images →OpenCheck a page against WCAG 2.2 — contrast, labels, headings and the new 24-pixel target size rule — with the exact change needed for each failure.
Check a page →The files people most want to convert are the files they should be most careful with: a scan of a passport, a signed contract, a payslip, a medical letter. The mainstream tools for these tasks require you to upload the document to a company you know nothing about, and then trust a retention policy you cannot verify. Doing the work in the browser removes the question entirely. Nothing is transmitted, so nothing can be retained, logged, or leaked.
There is a trade. A browser cannot do everything a server can — rendering PDF pages as images and converting Office documents both need engines too large to ship to a page. Where that is the case it is said plainly on the tool rather than worked around.
