PDF & Image

3 free tools

Convert, compress and merge PDFs and images.

PDF and image tools that keep your files private

Most online PDF tools upload your documents to a server, process them there and ask you to download the result. Logicox does the work inside your browser instead. Your bank statement, ID card or exam form is read by your own device and never sent anywhere, so there is nothing to delete afterwards and no waiting for an upload on a slow connection.

Which tool do you need?

  • Merge PDF joins several PDF files into one. Drag them into the order you want before you save.
  • JPG to PDF turns photos of documents into a single PDF, one photo per page, the right way up.
  • Image Compressor reduces a photo to a target size such as 50 KB or 100 KB, which many online application forms require.

Common jobs

For a job or university application that wants one PDF with all your documents, photograph each page, combine the photos with JPG to PDF, then add any PDFs you already have with Merge PDF. If a form rejects your photo or signature for being too large, run it through the Image Compressor and pick the size limit the form asks for.

All three tools work on Android and iPhone as well as on a computer.

Frequently asked questions

Are my files uploaded to Logicox?

No. The PDF and image tools run in your browser, so your files are processed on your own device and are never sent to our server.

Is there a file size or page limit?

There is no fixed limit. Because the work happens on your device, very large files depend on how much memory your phone or computer has. Files of 50 MB or more usually work fine on a recent device.

Do these tools work on a phone?

Yes. They are built for phones first and work in Chrome, Safari and other modern browsers on Android and iPhone.

Will the tools add a watermark?

No. The files you save have no watermark and no extra pages.
