Are my PDFs uploaded anywhere?

No. The files are read and processed by your browser and the result is created on your device, so the document is never sent to a server. That is why these tools have no daily limits and no sign-up.

How do I make a PDF small enough for an upload limit?

Start with the PDF Compressor, which removes redundant data and metadata without touching quality. If a form insists on a hard limit such as 200 KB, use the size-specific compress pages, which aim for that limit and show the size you got. Splitting a long document into parts is another way to stay under a limit.

Why did my PDF barely shrink?

Lossless compression can only remove redundancy inside the file, such as unused data and metadata. A scan, or a document full of photographs, is mostly image data, and the only way to make that much smaller is to store the images at lower quality. For those files, a size-targeted compress page will do more than the lossless tool.

Can I merge PDFs and choose the order?

Yes. The PDF Merger lets you add several files, drag them into the order you want and download one combined document. Image files can be turned into pages first with the Image to PDF tool.

Is there a file size limit?

There is no server limit because nothing is uploaded. Very large PDFs depend on your device's memory and processor, so a file of many megabytes may take a while on an older phone.

Free PDF Tools

PDF tools for the small jobs that every form, application and email attachment seems to need: merging several files into one, splitting out a few pages, rotating a scan that came in sideways, adding page numbers or a watermark, turning photos into a PDF, and making a file smaller. They run in your browser with open-source PDF libraries, so the document is read from your device and the result is built there too. Nothing is uploaded.

That matters for payslips, ID scans, contracts and bank statements, which you may not want to hand to a stranger's server. The trade-off is that very large files depend on your device's memory, and a password-protected PDF has to be unlocked before it can be changed here.
